dc.description.abstractThe present investigation was carried out to study the floral biology and breeding behaviour in kalmegh (Andrographis paniculata) and safed musli (Chlorophytum borivilianum). The research work was conducted during May 2006-Jan 2007 at CCS Haryana Agricultural University, Hisar. In Andrographis paniculata studies on floral biology showed that, flowering was at low rate initially during October, gradually increased to peak in November followed by cessation during mid December. Inflorescence is racemes lax. Floral formula is:. The flower bud from visible stage to come to full bloom took 11-12 days with a flowering duration of about 95 days. More than 74 per cent floral buds opened between 8.00-10.00 a.m. anther dehiscence occurred in synchronization with flower opening. Pollen viability at the time of flower opening by acetocarmine test was found to vary from 79-83 per cent. Pollination experiments revealed the self-pollination or self-compatibility breeding system in Andrographis paniculata, However possibility of cross-pollination to a certain extent could not be ruled out. In Chlorophytum borivilianum studies on floral biology and breeding behaviour showed that the inflorescence was raceme. The floral formula is:. The flower opening was asynchronous. The flower bud took 7-8 days to come to bloom with the flowering duration of about 21 days. More than 64 per cent of the flower buds opened between 9.00-10.00 a.m. Pollen viability by acetocarmine test at the time of flower opening was found vary from 84-88 per cent. It could be established by pollination experiments that safed musli is a cross fertilizing species.en_US
