A Study of Blossom Biology in <I>Solanum khasisnum</I> Clarke

Abstract

A study of blossom biology was carried out in two selections, i.e., JRL-28 and JRL-12, of S. khasianum. The development of flowers after the emergence of buds required 20 and 25 days, and blooming period were 120 and 150 days in case of JRL-28 and JRL-12, respectively. The duration of flowering was recorded to be 100 days. The anthesis occurred between 5.00 A.M. And 8.30 A.M., and the flowers fully opened between 7.30 A. M. and 9.45 A. M. The pollen grains were 25.2 - 29.4 μ and 25.2 - 33.6 μ in size, having 95.67% - 97.21% and 91.16% - 96.16% viability in JRL-28 and JRL-12, respectively. The stigma were most receptive at the time of anthesis.
