This experiment was conducted to study the effect two types of biochar and nitrogen fertilizers amendment, with different rates on morphological attributed of garland chrysanthemum plant. Two different types of biochar (BT) Eucalyptus biochar (EB), and Salix biochar (SB), four biochar rates- BR (at 0, 1, 2 and 3%), and three rates of nitrogen fertilizer- NR (0, 140 and 280 mg kg-1) with three replications on plant growth were used in this research. The (Chrysanthemum coronarium L.) was used as a test plant to study some morphological characters including: Plant Height (PH) cm, Fresh Weight Per Plant (FWP) g, Number of Leaves Per Plant (NLP), Stem Diameter (SD) cm, Flower Diameter (FD), Number of Flower Per Plant (NFP) and Number of Flower Bud Per Plant (NFBP) cm. The Double Barrel Design was used for making biochar by pyrolysis system. The experiment was conducted in the plastic house condition. The results showed that biochar applications at a rate of 3%, significantly increase PH, FWP, NLP, SD, FD, and NFBP, while NFP increased only at 2% biochar application and decrease at the 3% rate. The application of 280 mg kg-1 of nitrogen significantly increased all of the parameters. The plant grown in the soils amended with the EB were higher than grown in the soils of the SB. In addition, the best value in the study was observed were biochar combined with nitrogen fertilizers.

An investigation was carried out to evaluate the growth and the flowering of some of the commercial annual flower crops as intercrop in coconut ecosystem. Commercial annual flower crops viz., African marigold, French marigold, celosia, gomphrena and China aster were grown as an intercrop in coconut plantation and also under open condition for comparison. The results of the experiment showed that all of the crops performed to its optimum in the coconut shade, but less well than the open condition. The parameters viz., Plant height, internodal length, number of lateral branches, days taken for first flowering, flower diameter and yield were recorded. The yield was relatively higher in the open condition. The morphological characters were higher in the open condition and the earliness to flower bud initiation and flowering were observed in the open condition.

Seeds of marigold cv. ‘Pusa Narangi Gainda’ were treated with different gamma irradiation treatments viz, control, 25 Gy, 50 Gy, 75 Gy, 100 Gy, 125 Gy and 150 Gy and evaluated for various morphological characters. Reduction in survival percentage, plant height, number of branches and plant spread was observed after irradiation and with increase in exposure of gamma rays. Early flower bud initiation and flower opening was observed in lower dose of gamma rays. Flower diameter, number of flowers and length of peduncle was significantly highest at the lowest dose of gamma irradiation. The stimulatory effect of gamma irradiation was observed at 25 Gy in almost all the characters, though the intensity of inhibition increased with increasing exposures of gamma rays. On the basis of present observation, it may be concluded that irradiation of gamma rays of 25 Gy was found to be beneficial for growth and flowering characters in African marigold cv. Pusa Narangi Gainda

SUMMARYJojoba [Simmondsia chinensis (Link) Schneider] is a dioecious plant grown for its seeds, which are the source of liquid wax or jojoba oil. The sex of jojoba plants cannot be determined with morphological characters until the plants reach reproductive maturity at 3 or more years old. This difficulty of early sex determination imposes severe constraints in breeding studies and in the sex allocation of seedlings in seed orchard establishment, and importantly in a priori mating designs to produce superior jojoba individuals. This study reports three new cleavage-amplified polymorphic sequence (CAPS) assays, which identify male and female individuals distinctly. One of the assays could also identify hermaphrodite jojoba plants existing in nature or obtained using mutagenesis studies.

Four heat-tolerant (`Celebration Cherry Red', `Celebration Rose', `Lasting Impressions Shadow', and `Paradise Moorea') and three non-heat-tolerant (`Lasting Impressions Twilight', `Danziger Blues', and `Pure Beauty Prepona') cultivars were identified using a Weighted Base Selection Index. These cultivars were used as parents in a full diallel crossing block with reciprocals and selfs. Progeny from five parents (25 crosses) were evaluated for heat tolerance. Four floral (fl ower number, flower diameter, flower bud number, and floral dry weight) and five vegetative characteristics (visual rating, leaf size rating, vegetative dry weight, branch number, and node number) were evaluated with emphasis placed on continued flowering under long-term heat stress. In addition, progeny from all seven parents (49 crosses) were evaluated for inheritance of adaxial leaf color, abaxial leaf color, vein color, and flower color. Significant differences were found in each data category (P < 0.001) with the exception of node number, which was not significant. Flower number varied from 0 to 2, flower diameter varied from 0 to 41 mm, floral dry weight varied from 14 to 105 mg, bud number varied from 0 to 12, branch number varied from 5 to 15, and vegetative dry weight varied from 220 to 607 mg. General and specific combining abilities of the parents were evaluated as was heritability. It was found that the four heat-tolerant cultivars had higher general combining abilities. Heat tolerance has low heritability and is controlled by many genes.

The study was conducted to determine the effect of duration of night interruption using incandescent bulbs on sustained quality flower production of potted standard Chrysanthemum cv. Kikiobiory. The different night interruption (NI) treatments i.e. control, <5 sec. flash, 30-, 60-, 90- and 120- min. significantly (p<0.05) affected allthe vegetative and floral parameters. The plant height, number of leaves and root suckers per plant increased with the increase duration of NI treatments with maximum at 120- min. NI (90.42 cm, 34.75 and 12.10, respectively). The days taken to flower bud appearance, colour break stage and full bloom were delayed, whereas flower quality with respect to duration of flowering and flower diameter were deteriorated with increase in duration of NI treatments. The days taken to flower bud appearance, colour break stage and full bloom were highest at 120- min. NI (136.84, 183.22 and 202.25 days, respectively) which delayed the flowering by 63.94 days, where full bloom flower appeared in March. There was reduction in duration of flowering and flower diameter with increased NI duration with lowest at 120 min. NI (7.83 days and 15.69 cm). It was observed that increase (120 min.) in night interruption increased the vegetative growth and delayed the flowering; however, flower quality was deteriorated. Thus, it was concluded that 60 min. NI improved flower quality with sustained flower production in potted Chrysanthemum cv. Kikiobiory.

Main Food Source

Keeping quality is an important parameter for evaluation of rose cut flower quality, both in export and domestic markets as fresh cut rose flowers are highly perishable due to limited water uptake and low available energy. Carbohydrate is the main food source to maintain the energy requirement for flowers .An experiment was conducted at Horticulture Laboratory of Institute of Agriculture and Animal Science, Lamjung, Nepal on January 2017 in order to find out best concentration of sucrose that enhances and prolongs the better flower quality and longevity. Experiment was laid out with 10 treatments viz. tap water, tap water + 2% sucrose, tap water + 4% sucrose, tap water + 6% sucrose, tap water + 8% sucrose, distilled water, distilled water + 2% sucrose, distilled water + 4% sucrose, distilled water + 6% sucrose and distilled water + 8% sucrose under completely randomized design with three replications. Rose sticks were harvested at flower bud stage and two sticks were kept in each vase solution. Effect of different concentrations of sucrose solution on water uptake, weight gain or loss, neck bending, flower diameter, days to full bloom and vase life was affected significantly. The rose flower held in distilled water + 6% Sucrose was recorded to have higher value (7.77cm) for flower diameter at 10 days followed by Tap water + 6% Sucrose with value 7.62cm. Similarly, lower flower diameter (2.29cm) was observed in Tap water at Day16 followed by Distilled water with value 3.21cm. Similar pattern was observed in all other parameters having highest vase life (19.5 days) in Distilled water + 6% Sucrose and lowest (15.17 days) in tap water only. Among different concentrations of sucrose solution, distilled water + 6% sucrose was found highly effective for longevity of cultivar.

The ornamentally important genus Adonis L. (Ranunculaceae) consists of about 30 species. In Iran, 8 species are recognized. The new classification system recognizes two subgenera, six sections, and six series for Adonis. The species differentiation within the genus is controversial due to morphological overlaps in different species and extensive morphological variation. Therefore, the aims of present study were: 1- Species delimitation within the Sect. Adonis based on morphological and molecular evidences and, 2- Studying the species relationship based on molecular phylogeny. Multivariate analyses of morphological and molecular (ITS and ISSR) data differentiated the Adonis species. PCA biplot analysis of morphological characters revealed morphological characters such as leaf arrangement; leaf length, flower diameter, petal length and width, calyx length, and pedicel length are of taxonomic implication in Adonis. Bayesian tree of ITS sequences revealed that the sect. Adonis is differentiated from the sect. Adonanthe. Based on ITS data, A. microcarpa showed close affinity to A. scrobiculata, while A. aestivalis, A. icrocarpa and A.dentata were close to each other.

The cut rose, grown as a single-stemmed crop, resembles a potted plant and can be adapted to transportable bench systems. Potentially, this cultivation method could increase control of rose development, flexibility of production and produce, and automation of difficult or laborious cultural operations. Synchronous growth and flowering is considered important. The effects of increased quantum irradiation integral and plant density on shoot growth, fresh biomass production, and bloom quality were studied as single-stemmed rose plants (Rosa hybrida L.) `Kordapa' Lambada, `Tanettahn' Manhattan Blue, `Tanorelav' Red Velvet, and `Sweet Promise' Sonia grown under 20 hours photoperiods at 23 °C average air temperature. Plants were grown in rockwool cubes on ebb and flood benches irrigated with a complete nutrient solution, and were supplied with carbon dioxide at 1000 μmol·mol-1. Increased the daily quantum integral from 17.8 to 21.0 mol·m-2·d-1 increased fresh biomass efficiency, stem diameter, and specific fresh mass while number of nodes, number of five-leaflet-leaves, plastochron value, and stem length at anthesis decreased. Fresh mass at anthesis was not affected by the treatments. Increasing plant population density from 100 to 178 plants/m2 increased stem length at visible flower bud, and reduced both fresh biomass efficiency and specific fresh mass. These effects are suggested to be related to assimilate supply and translocation, and light perception of the roses. High quantum integral slightly reduced flower diameter but in general, quantum integral or plant density did not affect bloom quality or vase life. Use of preservative floral solution generally improved rose flower diameter and vase life. In Lambada increased light quantum integral prolonged vase life, but use of preservative solution did not. The cultivars Sonia and Red Velvet required 19 to 20 days from cutting/planting until onset of bud growth, 29 to 34 days until visible flower bud, and 39 to 49 days until anthesis. Red Velvet roses were ≈60 cm long at anthesis, and had larger stem diameter and growth rate, accumulated more fresh biomass, were most efficient producing fresh biomass, and had higher specific fresh mass among the cultivars. Light quantum integral is suggested to be used as a means to synchronize single-stemmed rose plant development.

The present investigation on Effect of organic and inorganic sources of nutrients on flowering of hybrid gerbera (Gerbera jamesonii B.) cv. Shimmer in open field condition was conducted at Biotechnology cum Tissue Culture Centre, OUAT Bhubaneswar during 2015-16 and 2016-17. The aim of the study was to find out suitable organic and inorganic sources of nutrients for cut flower production of gerbera in open field condition. There were eight treatment combinations consisting of 100% recommended dose of fertilizer (RDF), Vermicompost, 75% RDF, PSB, Azospirillum, Azotobacter and foliar spray of macro and micro elements. Application of 75% RDF (15:10:30 g NPK/10 plants) + Vermicompost (25 g/10 plants) + Azospirillum/ Azotobacter (20 g/10 plants) + PSB (20 g/10 plants) + macro and micro element spray recorded earlier flower bud initiation and flowering. The same treatments conducted to maximum length of flower stalk, thickness of flower stalk, flower diameter, number of flowers/plant and bloom life. It can be concluded that reduced dose of chemical fertilizer (75% RDF) along with application of vermicompost and biofertiizer can improve flower yield of gerbera in open field condition.

Background: Collar rot of lentil caused by Sclerotium rolfsii became a major problem for early sown lentil in North-eastern plain zones of India, as it associated with high yield losses every year. The disease cause huge loss in yield due to which, area under this crop is consistently decreasing. In global perspective, losses of 10-20 million dollars associated with S. rolfsii with yield depletion ranging from 1-60% in fields. The resistance and susceptibility of a potential host plant depends on the virulence of isolates of S.rolfsii. So the objectives of this study is to observe the potentiality of different isolates those were collected from major lentil growing districts of West Bengal and tested their virulence on three popular varieties of lentil. However the pathogenecity of S.rolfsii in this region never been tested before. This information could be a strong background for effective management of pathogen for future research.Methods: Collar rot infected samples were collected from different geographical locations of West Bengal during (Nov-Dec, 2018). And then the collected samples were isolated in Department of Plant Pathology, BCKV, Nadia, W.B. and were confirmed by their morphological characters. Result: The isolates from different geographical locations showed differences in their virulence. Among the all isolates SRC2 considered as most virulent as it causes highest diseases incidence as well as mortality percentage in all selected varieties of lentil. Two varieties, HUL-57 and BM-6 not so much popular among the farmers but can be consider as resistant to collar rot in case of early sowing condition.
