| dc.description.abstract | ABSTRACT The present investigations entitled “Reproductive Biology of Bauhinia vahlii Wight. and Arn.” was carried out in the Department of Tree improvement and Genetic Resources, Dr. Y.S.Parmar University of Horticulture and Forestry Nauni,Solan (HP) during 2016-2017 by studying selected tree climbers of Bauhinia vahlii from two populations namely S1(Jabli) in district Solan and S2 ( Jorhji) in district Sirmour of Himachal Pradesh. The type of inflorescence is terminal corymbose raceme. The flowers are zygomorphic, bisexual, pedicellate with superior ovary. At the flowering stage calyx has three sepals one free and two partially fused which also extend the physical support to the larger petals. Corolla consists of five petals; three being larger and two smaller. Maximum anthesis was recorded as 62.66 per cent and 59.99 percent during 6.00 am to 9.00 am in S1(Jabli) and S2(Jorhji) respectively. Anther dehiscence take place 2 to 3hrs after anthesis. The initiation of stigma receptivity was observed at about 2hrs after anthesis and remain receptive up to 48hour. This species was found to be open pollinated, mostly pollinated by insect vectors. Controlled crosses were made between the trees of two sites and maximum mean pod setting was recorded in S2 (Jorhji).The pollen viability was found to be maximum from the buds, before anthesis. Pollinators were identified to be Apis indica, Apis dorsata and aphids. The individual tree variability was recorded for hundred seed weight. The tree No. S1T1 registered maximummean seed weight(138.85g) for Site1(Jabli) and in case of Site2(Jorhji) maximum mean seed weight (140.54g) was recorded from tree No.S2T4 which was at par with S2T2 and S2T5.The maximum seed germination(82%) was obtained from S1(Jabli), under glasshouse conditions. The Genetic estimates for morphometric and floral traits showed high genetic coefficient of variability and higher heritability for leaf area, pod length, ovary length, and filament length which indicates that the selection for these traits can bring about effective and desirable improvement in the species by using appropriate mating designs. | en_US |
