Abstract
Comparative study with fluorescence microscopy revealed that the polle n tubes of the self-pollinated rice variety BR-9 reached the ovary wit hin 75 min after pollination. In P. coarctata it took 150 min. In the cross between P. coarctata and BR-9, pollen tubes reached the ovary in 165 min but seed setting was not observed. In the cross between BR-9 and P. coarctata, small and deformed pollen tubes were formed and they failed to grow through the stylodium.
