POLLEN FERTILITY IN GYNANDROPSIS GYNANDRA (LINN.)

In this research a local species, Gynandropsis gynandra was investigated cytologically with respect to its pollen fertility. The researchers analyses one thousand and fifty pollen grains out of which 325 were found to be morphologically sterile (31.0%) and 725 (69.0%) were morphologically fertile. Although the study reveals a high percentage of fertile pollen, not all the pollens may be viable as other studies have earlier revealed that nearly half of the morphologically fertile pollens were non viable. Hence the need for further research on pollen viability to establish the degree of fertility of the plant in question.
