Relevance and methodology. Lychnis coronaria is a perennial herbaceous plant with high decorative properties, with prolonged flowering in the second or third year of vegetation. The pubescent leaves form beautiful rosettes. The plant is undemanding to the growing conditions. The research material was the varietal population of Lychnis coronaria. The study was carried out in the open ground of the Moscow region (2014- 2021) on experimental plots of the flower crops sector of the FSBSI FSVC.Results. The most aligned form according to decorative features was identified – LC 1-21 with high seed productivity of inflorescences, decorative and winter hardiness. A variety testing and preliminary reproduction of a promising cultivar of Lychnis coronaria was carried out. This variety was transferred to the FSBI "State Export Commission" in 2021 under the name “Malinovy Rassvet”. Such signs as "plant height", "bush diameter", "number of ornamental shoots", "flower diameter" had a low or average variation value, which characterizes this sample as the most aligned. Thus, the cv. “Malinovy Rassvet” of Lychnis coronaria is recommended for cultivation and use for decorative purposes. The leaves and the bright color of the flowers provide a contrast to the perennial borders and flower beds. It looks good both in single and group plantings, as well as in cutting. It is grown as a short-lived perennial. The main advantages of the variety are the color fastness of flowers when burned out in the sun, resistance to diseases and pests, high seed productivity.

An important element of climate change is to assess changes in agro-climatic growing conditions of crops and the impact of these changes on their performance. Agriculture is the most vulnerable sector of  Ukraine's economy to fluctuations and climate change. Given the inertial nature of agriculture and the dependence of the efficiency on the weather, now need to make timely and adequate solutions to complex problems caused by climate change. Due to the expected increase in air temperature of the Northern Hemisphere food security Ukraine will largely depend on how effectively adapting agriculture to future climate change. This includes advance assessment of the impact of the expected climate change on agro-climatic conditions for growing crops. Potatoes - perennial, herbaceous, plant, but in nature is treated as an annual plant, so that the life cycle, beginning with germination and ending with the formation of bubbles and the formation of mature tubers, is one growing season. Potato is one of the most important crops grown and diversified use in almost all parts of our country. But the main focus areas of potatoes in Polesie and Forest-steppe. We consider the relative performance of the photosynthetic productivity of potato and agro-climatic conditions for growing potatoes for the period 1986 to 2005, and expected their changes calculated by the climate change scenarios A1B and A2 for the period 2011 to 2050 in Eastern and Western Forest-Steppe. We consider the agrometeorological and agro-climatic conditions in which there may be a maximum performance of potato.

The main parameter of the breeding work with alfalfa in the ARC “Donskoy” is the improvement of fodder and seed productivity. Through the years the breeding work was carried out with 500–860 collection samples of alfalfa, alfalfa hybrids and alfalfa lines of the local origin. The main method of the breeding work was poly-crossing. It’s characterized with a multiple repetition of selections of the best plants from the populations, their self-pollination and crossing by free pollination in the plots of poly-crossing. It resulted in accumulation and concentration of favourable traits in the population. The selection promoted systematic improvement of synthetic populations according to economic-valuable traits, especially fodder and seed productivity. During the research, productivity of green mass of the standard variety ‘Rostovskaya 90’ was 28.2 t/ha in the first cutting and 19.0 t/ha in the second one on average. The varieties ‘Lyutsiya’ and ‘Selaynka’ produced 30.6 t/ha, 19.8 t/ha and 32.1 t/ha, 20.4 t/ha respectively. The sum of the harvested green mass of the standard variety was 47.2 t/ha, while ‘Lyutsiya’ produced 50.5 t/ha and ‘Selaynka’ 53.1 t/ha, that is on 7.0% and 12.5% larger than the standard. The similar result was obtained in productivity of dry matter. The total quantity of dry matter produced by the standard variety was 11.6 t/ha (two cuttings), the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 12.6 t/ha and 12.8 t/ha that is on 8.6% and 10.3% more than the standard. The estimation of the breeding work with alfalfa in the preliminary and competitive variety testing allowed to identify the new alfalfa variety ‘Golubka’ and to send it to the State Variety Testing. In the competitive variety testing (2012–2016) the variety produced larger yields that the standard variety (productivity of all five 1-st cutting). With its average productivity of green mass (31.9 t/ha) it exceeded the standard on 13.1%. In the 2-d cutting its green mass productivity was 20.9 t/ha that is on 10.9% more that the standard.  With the average productivity of green mass the variety ‘Golubka’ produced 8.0 t/ha in the 1-st cutting and 4.9 t/ha in the 2-d, that is on 12.7% and 8.9% lager that that of the standard.  The variety ‘Golubka’ produced 52.8 t/ha green mass for two cuttings and 12.8 t/ha dry matter that is on 11.9% and 10.3% larger than the standard variety ‘Rostovskaya 90’. Seed productivity of the standard variety was 0.23 t/ha on average, the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 0.25 t/ha, the new variety ‘Golubka’ produced 0.29 t/ha, that is on 8.7 and on 26.1% more than the standard.

AbstractIris germanica L. is a perennial herbaceous plant that has been widely cultivated worldwide and is popular for its elegant and vibrantly colorful flowers. Selection of appropriate reference genes is the prerequisite for accurate normalization of target gene expression by quantitative real-time PCR. However, to date, the most suitable reference genes for flowering stages have not been elucidated in I. germanica. In this study, eight candidate reference genes were examined for the normalization of RT-qPCR in three I. germanica cultivars, and their stability were evaluated by four different algorithms (GeNorm, NormFinder, BestKeeper, and Ref-finder). The results revealed that IgUBC and IgGAPDH were the most stable reference genes in ‘00246’ and ‘Elizabeth’, and IgTUB and IgUBC showed stable expression in ‘2010200’. IgUBC and IgGAPDH were the most stable in all samples, while IgUBQ showed the least stability. Finally, to validate the reliability of the selected reference genes, the expression patterns of IgFT (Flowering Locus T gene) was analyzed and emphasized the importance of appropriate reference gene selection. This work presented the first systematic study of reference genes selection during flower bud development and provided guidance to research of the molecular mechanisms of flowering stages in I. germanica.

Relevance. The specifics of the fresh cut flowers market in the Russian Federation is such, that 85-100% of the total volume of flowers sold is imported. The most popular flowers among Russian consumers are roses (up to 60% in the total share of fresh flowers), chrysanthemums and carnations, all of which require certain growing conditions. Recently, the market of local seasonal flowers has begun to develop, the main players in which are small farms or household plots. Material and methods. This article presents the data about market analysis of fresh cut flowers in Russia for the last five years (2015-2020). For this analysis were used the methods applied in economics. The main information database of this research includes data from official state statistics; open data from analytical centers; federal and regional regulations; data from the Federal agency for technical regulation and Metrology; reference materials of specialized data on research field; data from industry-specific portals; sites; articles and reviews written by producers of fresh cut flowers in Russia and worldwide. Results. Russia is one of the top six importers of fresh cut flowers in the world. The most popular flower among Russian consumers is a rose. There is not much suitable soil and climatic conditions in Russia for growing it on a commercial scale in the open ground. In 2018-2019 according to Rosstat data the number of flowers, grown for cutting in Russia, was estimated 263,3 billion pieces. However, now Russian flower producers are not able to meet domestic demand for fresh flowers, so there is no almost export.

Daylily (Hemerocallis) is a perennial herbaceous plant widely used in landscape gardening. Daylilies are prized for their long term flowering mainly in late summer and low maintenance cultivation. According to flower spike height, the varieties are divided into runt, medium-growing and tall. The article contains the results of the study of 21 medium-growing daylily varieties’ terms of flowering in the botanic garden of the Volga region State University of Technology (Yoshkar-Ola, the Republic of Mari El). The research was conducted in 2015 - 2017. The calendar dates were converted into a continuous series. All varieties were classified as early, medium or late according to the terms of the beginning and the end of flowering and its duration. During three years of research, the earliest beginning of the phenological phase was registered in 2016, and the latest one  - in 2017. The early beginning and ending of flowering were typical for the varieties “Dr Regel” and “Royal Sovereign”. The late beginning of flowering was registered for the “Country Club” variety, and the late ending - for “Sandalwood”. Other varieties were classified as medium-term. The varieties “Royal Sovereign”, “Tejas”, and “Sugar Candy” are characterized by a short flowering period, while “Sandalwood” and “Derby Bound” - with a long one. It was established that the late-flowering varieties are characterized with a longer flowering period.

Atractylodes macrocephala is a perennial herbaceous plant (family Asteraceae) native to China. The biennial root, Largehead Atractylodes Rhizome (LAR), is the most commonly used Chinese herbal medicine to prevent early pregnancy loss due to miscarriage. From summer 2010 to spring 2012, symptoms of root rot were observed on LAR in Xianfeng county, Enshi city, Hubei Province, China. White mold on the root of LAR could be observed at an early growth stage in the field and the white mold spread over the entire plant after 10 days, which differs from root rot of LAR caused by Fusarium oxysporum and Rhizoctonia solani, neither of which are characterized as having mycelium spreading over the whole plant (4). Where root rot symptoms were present, rhizome yield was reduced by 15% on average, with up to 40% yield loss in some fields. Under humid conditions in mid-June, the disease in the field spread quickly and the rhizomes of LAR were completely rotted. After rainfall and increasing temperature from 16 to 35°C, white mycelium appeared and plants withered within a few weeks. In April 2011 and 2012, a fungus was consistently recovered from symptomatic rhizome samples after they were surface sterilized with 0.1% mercuric chloride solution and plated onto potato dextrose agar (PDA). Pale gray colonies with short aerial mycelia and brown sclerotia formed on PDA after 7 days incubation at 28°C. Binucleate cells were observed using light microscopy and the characteristics were matched with morphological characteristics of a Ceratobasidium sp (3). Genomic DNA of the culture was extracted, and the rDNA-internal transcribed spacer sequence (GenBank Accession No. JQ926741) showed 99% identity to Ceratobasidium sp (GenBank No. H269825.1). Mycelial plugs of the culture taken from PDA were inoculated onto 40 rhizomes of 1-year-old seedlings and plants were incubated with a 16-h photoperiod at 28°C and 90% relative humidity in an artificial climate chamber where they developed typical disease symptoms after 2 days. Ten rhizomes of 1-year-old seedlings and were treated with PDA plugs only. All seedlings inoculated with the pathogen were withered and the rhizomes were completely covered with gray mycelium 2 days after inoculation, which was similar to the symptoms observed in the field. After 7 days, the symptoms were more severe than those observed in the field, with seedlings rotted completely. The main stalk of all inoculated plants was covered with gray mycelia in 4 days, and the stalk became withered, which was similar to the symptoms observed in the field. No symptoms were observed on control seedlings and plants. Koch's postulates were fulfilled by successful reisolation of Ceratobasidium sp. from diseased seedlings. The pathogenicity tests were carried out twice. Ceratobasidium sp. has been reported to cause root rot of canola in Washington (2). It has also been observed on Rehmannia in China (1). To our knowledge, this is the first report of Ceratobasidium sp. causing root rot on LAR. References: (1) B. B. Chen et al. Chin. J. Chin. Material Medica (In Chinese) 9:1137, 2011. (2) K. L.

Baphicacanthus cusia is a perennial herbaceous plant in the family Acanthaceae that is native to China, where it grows in warm temperate mountainous or hilly regions. It is commonly used as a Chinese herbal medicine. In March 2012, symptoms of leaf spot were observed on leaves of B. cusia in Long'an County, Guangxi, China, where this plant is extensively cultivated. Symptoms were initially small brown dots which developed into irregular to circular leaf spots. These spots enlarged and overlapped, extending until the 7- to 9-cm-long and 3- to 4-cm-wide leaves withered entirely, mostly within 2 months. On potato dextrose agar (PDA), the same fungus was cultured from 92% of 75 symptomatic leaf samples that had been surface sterilized in a 45-second dip in 0.1% mercuric chloride. Fungal structures were observed on diseased leaves: conidiophores (85 to 460 × 4 to 8 μm) were erect, brown, single or in clusters, and conidia (36 to 90 × 5 to 16 μm) were single or in chains of two to four, brown, cylindrical or obclavate, straight or slightly curved, with 3 to 18 pseudosepta and a conspicuous hilum. Three single-spore isolates were identified as Corynespora cassiicola (Berk & Curt.) Wei based on morphological and cultural characteristics (1). The rDNA internal transcribed spacer (ITS) region of one isolate, ZY-1, was sequenced (GenBank Accession No. JX908713), and it showed 100% identity to C. cassiicola, GenBank FJ852716, an isolate from Micronesia cultured from Ipomoea batatas (2). Pathogenicity tests were performed with each of the three isolates by spraying conidial suspensions (5 × 104 conidia/ml) containing 0.1% Tween 20 onto the surfaces of leaves of 60-day-old, 20-cm tall plants. For each isolate, 30 leaves from five replicate plants were treated. Control plants were treated with sterilized water containing 0.1% Tween 20. All plants were incubated for 36 h at 25°C and 90% relative humidity in an artificial climate chamber, and then moved into a greenhouse. Seven days after inoculation, dark brown spots typical of field symptoms were observed on all inoculated leaves, but no symptoms were seen on water-treated control plants. Koch's postulates were fulfilled by reisolation of C. cassiicola from diseased leaves. To our knowledge, this is the first report of C. cassiicola infecting B. cusia worldwide. References: (1) M. B.

Lily (Lilium longiflorum) is a perennial herbaceous plant with white trumpet-shaped flowers, fragrant and bulbous. In vitro culture through bulbs is one of way propagation of lily plants, but it requires a long time and only produces limited plants. In vitro propagation is a very promising technique for plant propagation because it can produce a lot of plant seeds in a short time. Bulbs are one of the fastest explants for growing shoots in lilies, but it is not known for certain which cuts of explants from bulb scales are best for multiplying in vitro. This study aims to determine the effect of lily bulb explants and the concentration of NAA and BAP growth regulators on the growth of lily bulb explants. The best results were obtained on the base and middle cuts explant of bulb scales compared to the tip cuts explant ones. The best results of the growing percentage, the number of shoots and the best growing time are shown in the combination treatment of growth regulator 1 mg L−1 NAA and 1 mg L−1 BAP. The optimum results on the number of micro bulbs were found in the treatment of growth regulators 0.5 mg L−1 NAA and 1 mg L−1 BAP. The best results of the average time formed micro bulb was in the treatment of 1 mg L−1 NAA and BAP with middle explant cuts, and treatment concentrations of 0.5 mg L−1 NAA and BAP in the base explant section. The base and middle bulb explants are able to regenerate or grow higher shoots. This is caused by the presence of endogenous natural auxin and the spread of auxin in plant parts not in the same amount. Therefore when added to the exogenous growth regulator such as auxin or cytokines to culture media will further trigger the formation of micro tubers more quickly,. It can increase the concentration of endogenous growth regulators in cells, help growing process and developing tissue.   Keywords: Bulb, lily, micro bulbs, in vitro, shoots
