STUDIES ON FLORAL PHENOLOGY IN PONGAMIA PINNATA L., A BIODIESEL PLANT
Pongamia pinnata seed oil could be as a source of biofuel from which enormous potential of high seed oil can be produced. The collection of pods with higher seed quality characters is much important for production of elite seedlings at nursery and hence studies related to seed maturation were initiated as matured seed is the basic character of quality seed. To study the steps in obtaining quality seed from the tree, studies were initiated on floral phenology. Randomly selected trees from 23 accessions of Pongamia planted in August, 2005 were selected for the studies conducted in two consecutive years, i.e. 2012-13 and 2013-14. The results revealed that in Pongamia accessions studied, the racemes per branch ranged from 13 to 112, buds per racemes ranged from 25 to 80 and 0-64 total number of flowers opened in a day in the year 2012-13. In the year 2013-14, the racemes per branch ranged from 8 to 246, buds per racemes ranged from 0 to 76 and 14-67 total number of flowers opened in a day. On an average 6.57g and 2.14g fresh and dry biomass, respectively was obtained. These studies will help in further investigation of pod and seed studies.
