A Preliminary Note on Pollen in Teak in Relation to Fruit-set

The pollen grains of Teak from Pune, Nagpur, Chikhalda, Hadapsar, Padve-Mazgaon and Chanda were examined. The pollen morphology was studied. There were no significant differenee in size of pollen grains of one location to other location. The percentage of sterile pollen grains in those ecotypes range from 1.94 to 16.50. 18 to 16 per cent of the pollen grains inside the sathers were found to be germinated in Teak of Pune origin. Since the proportion of the Sterile and germinated pollen grains is low, these may not be the factors contributing to the poor fruit set in Teak. Investigations on pollen viability and stigmatic receptivity are suggested to uoderstand the floral biology aDd fruit-set.
