Flowers could be produced in culture about 5-6 months after seed sowing by appropriate, The morphology of flowering of several cultivars of Dioscorea rotundata , Poir is described. In this context, cross-pollinations are for great interest. Seedling development is described from seed germination to the establishment of several leaves on the seedling. Classification of crop plants based on mode of pollination and mode of reproduction Mode of pollination and reproduction Examples of crop plants A. Autogamous Species 1. The number of flowers per spike on A. mangium was almost double that on A. auriculiformis, but this difference did not affect the productivity of seeds. Vegetable crops. They offer the means of creating a wide genotypic variability. A legume (/ ˈ l ɛ ɡ j uː m, l ə ˈ ɡ j uː m /) is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. 1991 ) Chromosome doubling using colchicine Chaisan et al. 2007). In a breeding program for incorporating cyst-nernatode resistance of the green gram into the adzuki bean, an interspecific cross between a cultivar of the green gram and a semi-wild relatrve of the adzuki bean, in endemic name “Bakaso” was made recrprocally. 1991, Verma and Brar 1996. 2007, 2008). The pollen fertility was lower in F1 as compared to parents (Figure 2). July 15,1934 Authesis, Pollination, and Fertilization in Sorghum 125 TABLE 1.—Number of flowers blooming each hour in 4 panicles of Spur feterita during each day of their blooming periods Year Number of flowers opening at indicated hours Per- Day of blooming (no.) Chickpea (gram) can be grown as one crop or combine with barely, linseed, mustard, peas, corn, coffee, safflower, potato, sweet potato, wheat or sorghum etc. Among the pollination sequences, day 2 (the day after emasculation) contributed a greater percentage progeny (45%) than day 1 (35%) or 3 (20%). Its cultivation in India is about 3.25 million hectares and an annual production is 1.45 million tons. Hybrid plants were obtained from cultured embryos for the interspecific crosses of V. radiata x V. angularis, V. umbellata x V. angularis and V. angularis x V. umbellata. Pollen parents were homozygous dominant for a different one of the three marker genes. Black gram [Vigna mungo (L.) Hepper] is a tropical crop belonging to the Asiatic Vigna ... 1974). of inspections to be conducted. SYLLABUS FOR PRACTICAL Observation on floral biology – anthesis and pollination – selfing and crossing techniques ... Barn yard millet, Proso millet and Foxtail millet. (2006) Chromosome doubling using colchicine V. radiata × V. mungo Pande et al. Twenty-four uniform progenies, bulked in F7, were evaluated for yield potential. The fact that it was the only Vigna mungo in our garden was an added bonus as we didn't have to worry about cross-pollination. Sow black gram and green manure plant kolunchi or purple tephrosia (Tephrosia purpurea) together at the time of harvesting paddy. Mesophyll protoplasts of mung bean (Vigna radiata L. Wilczek) were electrofused with cell suspension-derived protoplasts of adzuki bean (V. angularis Ohwi & Ohashi) and subsequently cultured for several days. The fusion product started to divide after 5 days in culture. © 2013 International Formulae Group. Chronic exposure rates per day (20 h) were 1.54, 5.02, 7.33 and 10.0R on October 1, 1964.

Use the link below to share a full-text version of this article with your friends and colleagues. OPV* Hybrids. These findings highlight the importance of pollination by opportunistic avian nectarivores in Aloe. ISSD Myanmar, Component (2) organized one day training course of EGS production, characteristics of different varieties and quality control on groundnut, black gram and pigeon pea crops on 24th August 2019, in Monywa. This method was successfully used for Cicer arietinum L. and C. pinnatifidum L. Hybrid plants derived from Vigna mungo (black gram) and Vigna radiata (green gram) were favoured by the treatment of pistil with gibberellic acid (GA3), (Kaufmane and Rumpunen, 2002) up to 48 hours after pollination (, ... Vigna radiata × V. mungo Verma and Singh (1986), Ravi et al. Such situation is found in tomato and brinjal. Anther position. Varieties. Main improved attributes of mutant variety are early maturity, errect, photosensitive and determinate type. We found the hybrid acquired vigorous growth from V. umbellata and drought tolerance plus early flowering from V. exilis, and thus has taken over some habitats of V. exilis in limestone karsts. A true‐breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis.Pollinated pistils were treated with gibberellic acid (GA 3) (70 p.p.m.) 所需天數的分佈時間(GT90-GT10),(Imperial Blauwe Spiraal(和(Imperial Karmijn Koning(兩品種分別在5和10℃發 芽時最短,為9.1和7.8天。GFP、MGT、GT50、GT90-GT10在光照中或黑暗 下的結果相似。周年栽培生長試驗,以秋、冬兩季播種的植株的切花品質 才具有商品價值。兩種不同發芽溫度之植株表現差異小。(Imperial Blauwe Spiraal(和(Imperial Karmijn Koning(兩品種在苗期時,利用涼 溫(日/夜溫18/12℃)處理,13週的植株株高最高,分別為67.0和64.2公分 ,其切花品質最好。到花日數、株高、鮮重、總節數、花穗長度、小花數 目、著花節位、側枝數、頂部三節間長、莖粗均隨著處理涼溫期間增長而 增加。(Imperial Blauwe Spiraal(和(Imperial Karmijn Koning(兩品種 利用24小時長日處理的植株,分別較處理自然日長的植株早15.4和17.9天 開花,但切花品質不具商品價值。而處理自然日長株高最高,分別為97.8 和91.8公分,其切花品質最好。而利用暗期中斷長日處理的植株較處理自 然日長的植株可提早7.4和9.9天開花,其株高與自然日長處理的植株差異 不大。而利用暗期中斷處理60天的植株會比處理自然日長的植株,分別 早6.7和8.6天開花,且株高與自然日長處理的植株無顯著差異。 The cultivars of Delphinium ajacis L.(Imperial Blauwe Spiraal( and (Imperail Karmijn Koning( were used through this study.The objectives of this study were to determine the effects of different temperatures and light on seed germination of Delphinium ajacis L.,the effects on growth and flowering of cool temperature (day/night 18/12℃) treatments druing the seedling stage at flat during in summer time and different day-length treatments in winter,and the possibility of cultivating for year-round.The final germination percentage (FGP) of (Imperial Blauwe Spiraal( and (Imperail Karmijn Koning( both were the highest at 5℃,divided into 90.5% and 88.8%.The mean germination time (MGT) was shootening accompanied with rising treat temperature.It was the shortest at 15 ℃,divided into 16.1days and 16.2days.Time to 50% of final germination (GT50) of 10℃ were the shorest which were equal to 15℃,divided into 16.1days,16.2days and 15.5days,15.7days.Days from 10% to 90% of final germination (GT90-GT10) of (Imperial Blauwe Spiraal( were shortest at 5℃ which were 9.1days.GT90-GT10 of (Imperial Karmijn Koning( were shortest at 10℃ which were 7.8days.FGP、 MGT、GT50、GT90-GT10 were about equal in light or darkness.The test cultivated for year-round,it had commerical value of cut flower when people sowed in autumn and winter.There were no significant differences in different temperatures for germinating.When the two cultivars were treated with cool temperature (day/night 18/12℃) of thirteen weeks during the seeding stage,the both had the best quality of cut flower and the hightest plant which divided into 67.0cm and 64.2cm.Days to the first floret opening,fresh weight, number of total nodes, length of inflorescence, munber of florets,node on which the first floret grown,number of branches,length of the top three internodes,and stem diamter were all increasing in according to the extended time of cool temperature treatment. these three pollen sources. bicolor (Sorghum) . The wastewater contains valuable nutrients, but also contaminants, such as salts and chromium (Cr), that might affect soil processes and crop production. Ovary is superior, placentation is free central and the ovules are atropous. It was developed by treatment with chemical mutagen EMS (0.02%). Most of the distorted markers were clustered together and all the markers on LG8 were highly distorted markers. Male sterility, self-incompatibility and their role in hybrid seed production. Soc.

The broad, lustrous, dark purplish-black egg-shaped fruits range between four to six inches in diameter and are borne well off of the ground on medium sized plants. . (1985), Goshen et al. Black gram (Vigna mungo (L.) Hepper) is an dimportant pulse crop occupying unique position in Indian agriculture. Overall, it was found that desirable traits such as high pod number, seed weight, productivity and resistance to diseases have been introgressed successfully into black gram from ricebean. The pollen germination, Access scientific knowledge from anywhere. A considerable variation was found in leaf flushing, leaf fall, flowering and fruiting behaviour that could be partly attributed to abiotic factors. Using field observation and pollinator exclusion treatments, i.e. 499-501 ISSN 0972-5210 Introduction Black gram [Vigna mungo (L.) Hepper] is an important pulse crop of our country. This is the common form of out-breeding. In contrast, in reverse crosses, seeds are totally or partially empty and fail to grow. This much close position of anthers promotes self pollination, though cross pollination may occur too as flowers are open. 6, 59Ð60. ), vegetables, fruits, and other crops of economic significance. Here pollination occurs before floer opening (cleistogamous)in night. Comparison of domestication-related QTLs of the zombi pea with those of cowpea (Vigna unguiculata), azuki bean (Vigna angularis), mungbean (Vigna radiata) and rice bean (Vigna umbellata) revealed that there was conservation of some QTLs for seed size, pod size and leaf size between zombi pea and cowpea and that QTLs associated with seed size (weight, length, width and thickness) in each species were clustered on same linkage. A true‐breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis. Overall, pollination by opportunistic avian nectarivores amplified seed production per aloe ~7 and 10 times compared to insects and self-pollination, respectively. Pollination is of two types: viz. Male sterility, self-incompatibility and their role in hybrid seed production. In vitro flowering and in vitro pollination: methods that will benefit the orchid industry. 65, 330Ð339. The grains are hard and firm. The percentage increase/decrease in yield ranged from −35.48 to 50.31 over the check cultivar (‘Mash338’, female parent). Pollinated pistils were treated with gibberellic acid (GA3) (70 p.p.m.) Number of QTLs detected in each trait ranged from 1 to 5 with an average of only 2.3. embryogenesis studies and ploidy analysis. Pollinated pistils were treated with gibberellic acid (GA3) (70 p.p.m.) Valued for their grains with high and easily digestible proteins, these crops are also known as forage, green manure, and cover crops. (1979) P. vulgaris × P. lunatus Leonard et al. Apply at least 2 days before or after COPPER Split applications (at half -dose) not consistently better results were explained in terms of pollen viability, pollen germination on the ovule, Vegetative and reproductive phenology of 42 tree species of tropical forests at Kodayar in the Western Ghats, Tamil Nadu, India was monitored through fortnightly visits for two years. It belongs to the family leguminosae and subfamily papilionaceae. Seed Propagated Rice, Wheat, Barley, Oats, Chickpea, Pea, Cowpea, Lentil, Green gram, Black gram, Soybean, Common bean, Moth ANTHESIS AND POLLINATION • Pollination occurs a night prior to opening of the flowers • Anthers start dehiscing from 9 a.m and completely dehisced by 3 a.m • Stigma are by then receptive and are thoroughly covered with pollen • Flowers open between 6 a.m and 8 a.m and remain open till 11 a.m later they close between 2 p.m and 4 p.m 14. Hence the breeding cycles of orchid were reduced significantly. Hort. (Imperial Blauwe Spiraal( and (Imperail Karmijn Koning( treated with 24h day- length were 15.4days and 17.9days to the first floret opening than treated with natural day-length.But there were both no commerical value of cut flower.The plants treated with natural day-length both had the best quality of cut flower and the hightest plant which divided into 97.8cm and 91.8cm.The plants treated with night break were earlier 7.4days and 9.9days to the first floret opening than treated with natural day-length ,but there were no significant differences in the quality of cut flower.The plants treated with sixty days of night break and natural day-length which had no significant differences in the quality of cut flower between these,but the former got the first floret opening which were earlier 6.7days and 8.7days than the later. Comparing this V. vexillata linkage map with a previous linkage map of V. vexillata and linkage maps of other four Vigna species demonstrated several macro translocations in V. vexillata. The flower opens in the morning at 7 am. Working off-campus? Its hybridity was confirmed at the seedling stage based on the presence of the green epicotyl colour of the adzuki bean. 80 days — 'Black Beauty' is the classic, garden standard for eggplants and commonly seen at farmer's markets and on produce stands.
