TAILIEUCHUNG - Study of flower morphology, pollen viability, germination and their effect on fruit set in different cultivars of litchi

Litchi (Litchi chinensis sonn) is the most important fruit of the Sapindaceae family. It originated in China and is widely distributed in the tropics and subtropics (Knight, 1980). Litchi is an important sub-tropical evergreen fruit crop. Therefore, the present investigation entitled “Study of flower morphology, pollen viability, germination and their effect on fruit set in different cultivars of litchi” was carried out during 2017-18 in the Department of Horticulture (Fruit and Fruit Technology), BAC, Sabour,. For this experiment four litchi cultivars viz.,Purbi, Bedana, Shahi and China were chosen for the present study. On the basis of data recorded on date of panicle it can be concluded that the litchi cultivar Purbi having the maximum number of duration of panicle initiation (25days) and cv. China having minimum number of duration of panicle initiation (18 days). The flowering characteristics like duration of flowering, and date of anthesis has been the maximum duration of flowering in cv. Purbi (18 days) and earlier anthesis was observed in cv. Bedana 05-03-2018 and whereas minimum duration was observed in cv. China (10 days) and late anthesis in China 22-03-2018. The panicle length differed significantly among the litchi cultivars. The data clearly indicated that among all the cultivars studied, Purbi produced the maximum panicle length ( cm) which was at par with Shahi ( cm), while the minimum panicle length was found in China ( cm). The maximum panicle width was found significantly in Purbi ( cm) followed by at par Shahi ( cm), while the minimum width was observed in China ( cm). It was observed that three types of flowers emerged in all the four cultivars of litchi ., M1 male, Functional female and pseudo-hermaphrodite flowers. | Study of flower morphology, pollen viability, germination and their effect on fruit set in different cultivars of litchi
