FLORAL BIOLOGY, POLLINATION MECHANISM AND BREEDING SYSTEM IN BAUHINIA VARIEGATE LINN. | BIONATURE

Bauhinia variegata has a variety of flower colours despite being cytologically stable (2n =28). On the basis of blossom colour, Indian taxa have two varieties: var. candida and var. variegata. These floral variants' breeding mechanism and floral attributes are currently being studied. When the trees are leafless, these types bloom in February and March. Between 12.00-16.00h in var. variegata and 05.00-09.00h in var. candida, flower opening, anther dehiscence, and stigmatic receptivity occur synchronously. A flower's anthers all separate at the same time. Syrphids, beetles, and two bee species (Apis dorsata and A. mellifera) visit the blooms between the hours of 8 a.m. and 14 a.m., when pollen availability is at its highest. During the late evening, a moth (Syntomis cyssea-cramer) visits var. candida, but it does not appear to be an effective pollinator because there is very little pollen accessible. Agamospermy is not found in this species, but autogamy, geitonogamy, and xenogamy do.
