Обоснование. Изучение жизненности индивидуумов и виталитетной структуры популяций является одним из актуальных подходов в оценке состояния редких видов растений, к которым относится объект исследования. Цель. Определение структуры морфологической изменчивости и виталитетной структуры ценопопуляций Tulipa gesneriana L. на Ергенинской возвышенности. Материалы и методы. Исследования проводили в течение двух вегетационных сезонов в трех ценопопуляциях из разных растительных сообществ. Уровень изменчивости 12 морфологических признаков растений оценивали по С.А. Мамаеву. В структуре изменчивости выделяли группы системных индикаторов. Для оценки пластичности признака использовали индекс фитоценотической пластичности, виталитетного спектра популяций – методику Ю.А. Злобина, виталитетной структуры популяции – индекс виталитета, виталитетного типа – критерий Q, степени процветания или депрессивности ценопопуляций – индекс IQ. Результаты. Большинство изученных признаков растений T. gesneriana в первый год исследования имели большие значения, чем в следующем году, варьируя при этом преимущественно среднем и повышенном уровне. В следующем году уровень варьирования признаков возрос. Структуру изменчивости морфологических признаков T. gesneriana в первый год исследования слагали группы эколого-биологических и биологических системных индикаторов, в следующем году наряду с данными двумя группами появилась группа экологических системных индикаторов. Оценка жизненности ценопопуляций T. gesneriana выявила, что они относятся к типу «процветающие». Степень процветания ценопопуляций колебалась по годам. Заключение. Таким образом, ценопопуляции T. gesneriana относились к виталитетному типу «процветающие». Во второй год исследования в ценопопуляциях T. gesneriana, показатели жизненности ухудшались.

AbstractThrips hawaiiensis is a common thrips pest that damages the flowers of various plants. The differing population sizes of T. hawaiiensis among host plants suggest its preference and performance vary among host plants. In this study, the host fitness of T. hawaiiensis for different flowers was assessed through field investigation. The behavioral responses of T. hawaiiensis to the color and volatiles of flowers eliciting different apparent fitness levels and their development and survival on the plants were also studied. Adults and larvae of T. hawaiiensis were found in the flowers of 21 species, which were classified into four fitness levels for this thrips species. T. hawaiiensis showed significantly different visual responses to the color and olfactory responses to the volatiles of four tested flowers (each representing one of the four fitness levels), with the rankings of visual preferences for Dianthus caryophyllus > Tulipa gesneriana > Hydrangea macrophylla > Rosa rugosa, and olfactory preferences for H. macrophylla ≥ T. gesneriana > D. caryophyllus > R. rugosa. Plant species had significant influences on the development and survival of T. hawaiiensis, with developmental times from egg to adult of 9.58 d, 9.92 d, 10.35 d and 10.75 d on H. macrophylla, T. gesneriana, D. caryophyllus and R. rugosa, respectively, and corresponding survival rates of 76.33%, 71.33%, 64.00% and 59.00%. In summary, this study shows that olfactory preferences were consistent with the field performance of T. hawaiiensis on the four flower plants tested. Further, fitness levels of host plant flowers are correlated with development rate and survivorship of T. hawaiiensis. Our study adds to the understanding of the mechanism of host selection by thrips and provides basic information to underpin the management of T. hawaiiensis on horticultural plants.

Objective: To study the effect of Ce applied in a nutrient solution during the productive cycle, on the duration of the phases of the phenological cycle of tulip cv. Jan van Nes. Design/Methodology/Approach: Commercial bulbs (caliber 12+) were planted under shade cloth conditions during the autumn-winter period. The levels of Ce used were 5, 15 and 15 µM from CeCl3 7H2O; Ce was applied in the nutrient solution from the first day of the sowing, apart from the control without its application. Results: The different concentrations of Ce bulb sprouting. The low concentration of Ce (5 ?M) promoted the early formation of floral buds and their coloration. Hence, the application of 5 ?M Ce advances flowering of the tulip without exhibiting changes in the period of time to reach senescence. When 25 ?M Ce were applied, the opposite effects were observed. The duration of the flower was not significantly affected by the treatments. Study Limitations/Implications: This study was made only in one cultivar of tulip. Findings/Conclusions: The application of 5 µM of Ce had a positive effect in the tulip cycle, by stimulating bulb sprouting, the formation of the floral bud, the coloration, and the advance of the flowering cycle

This article presents results on the seed productivity of populations of Tulipa gesneriana L. in the Ergeninskaya Upland (within the boundaries of the Republic of Kalmykia). This species is listed in the Red Data Books of several regions of Russia, including Kalmykia. The research objects were 4 populations of T. gesneriana growing on the Ergeninskaya Upland, which extends across the Republic territory from north to southwest on light chestnut soils of solonetzicity. The potential seed productivity of these T. gesneriana plants was 161.8-181.5 pcs. seeds per plant; the actual seed productivity was 161.8-181.5 pcs. seeds per plant; and the formation of seeds was 34.4-75.6%. All indicators of seed productivity showed significant interpopulation differences when moving from the northern part of the Upland to its southern part. A potential reserve of mature seeds per 1 meter2 , formed during the growing season, in the coenopopulations of T. gesneriana was 253.2 - 3212.8 pcs. in 2018 and 368.0 - 1121.2 pcs. in 2017 on the Ergeninskaya Upland. Keywords: Tulipa gesneriana, coenopopulation, seed productivity, seed reserve

The study focused on the determination of phenolic acids, flavonoids and organic acids in five tulip cultivars ‘Barcelona’, ‘Columbus’, ‘Strong Gold’, ‘Super Parrot’ and ‘Tropicana’. The cultivars grown in field and in a greenhouse were exposed after cutting to different times of storage (0, 3 and 6 days). The phenolic profile contained 4-hydroxybenzoic, 2,5-dihydroxybenzoic, gallic, vanillic, syringic, salicylic, protocatechuic, trans-cinnamic, p-coumaric, caffeic, ferulic, chlorogenic and sinapic acids, as well as quercetin, rutin, luteonin, catechin and vitexin. The mean phenolic acid content was in the following order: ‘Columbus’ and ‘Tropicana’ > ’Barcelona’ > ’Strong Gold’ > ’Super Parrot’, while the levels of flavonoids were as follows: ‘Strong Gold’ > ’Barcelona’ > ’Tropicana’ > ’Columbus’ > ’Super Parrot’. The highest content of phenolic acids was confirmed for Columbus and Tropicana, while the lowest was for Super Parrot. However total phenolic content was very similar, observed between the place of cultivation, time of storage and cultivars. Malonic, succinic, acetic and citric acids were the major organic acid components in tulip petals. More organic acids (except malonic) were accumulated in tulip petals from fields than those from the greenhouse, while changes during storage were strictly correlated with cultivars.

Abstract We tested two sources of lanthanum (La), LaCl3 and La(NO3)3 × 6H2O at a concentration of 40 µM each, in the treatment solution of cut flowers of 15 tulip (Tulipa gesneriana L.) cultivars. Ascorbic acid (AsA; 0.2 g/L) was used as a reference solution, while distilled water was evaluated as an absolute control. With both La sources, bud length and diameter, and stem length were increased; as a result, stem curvature was also significantly increased with La treatments. The cultivars Laura Fygi and Rosario registered the highest relative stem elongation. Lalibela and Acropolis displayed the greatest stem curvature on the last day in vase. At 3, 5, 7, 9 and 11 days after cutting, the highest solution uptake was recorded in flower stems treated with LaCl3, surpassing the control by 5, 11, 15, 18 and 24%, respectively. The relative stem elongations observed were 21.3, 27.4, 35.2 and 35.5% in the control, AsA, LaCl3 and La(NO3)3, respectively. The mean solution uptake per gram of stem fresh biomass weight was 1.44, 1.44, 1.71 and 1.54 mL in the control, AsA, LaCl3 and La(NO3)3, respectively. LaCl3 significantly increased the bud length and solution uptake of flower stems, while La(NO3)3 × 6H2O increased stem fresh weight.

AbstractThis study was aimed to explore the composition and diurnal variation analyses of floral scent emission from Rosa rugosa Thunb. and Tulipa gesneriana L. The floral scent from the fresh flower were collected at different time points (9:00, 12:00, 15:00, 18:00, and 21:00) using dynamic headspace collection and were analyzed using autothermal desorber-gas chromatography/mass spectrometry (ATD-GC/MS). The results showed that a total of 62 volatile flavor compounds were detected from Rosa rugosa Thunb and a total of 70 volatile flavor compounds were detected from Tulipa gesneriana L. They were identified with eight functional categories: alcohols, fatty hydrocarbons, terpenes, aldehydes, ketones, esters, and other substances. The total release amount first decreased, and then increased with time, and arrived at the lowest at 15:00. The release amounts of different categories present distinct change patterns. Among the components, phenylethyl alcohol, citronellol, methylene chloride, hexane, and acetone showed relatively higher release amounts and were thought as the main components in floral scent of Rosa rugosa Thunb. Alpha-Farnesene, ethanol, pentadecane, beta-ocimene, longifolene, caryophyllene, and acetone showed relatively higher release amounts and were thought as the main components in floral scent of Tulipa gesneriana L. Research of roses and tulips in aromatic in the garden provides a theoretical basis and research and improvement of the aroma components of aroma.
