Abstract

Eichhornia crassipes (Mart.) Solms is an aquatic invasive weed throughout the tropical and subtropical regions of the world. The plant rarely produces any fruit under natural condition In order to understand the causes of failure of seed set in this plant various aspect of pollen biology were studied. Pollen fertility and pollen viability was assessed using Muntzing's mixture and in acetic orcein and TTZ, while pollen germination was assessed with different concentrations of sucrose supplemented with boric acid and Ca and Mg salts. The aim of the present study was to find out the cause of sexual incompatibility of Eichhornia crassipes (Mart.) Solms. In spite of high pollen fertility, pollen viability and pollen germination the species show hardly any fruit set under natural condition. The abnormal pollen germination like curling of pollen tubes, shrinkage of pollen tube tips and bending of pollen tube might be reasons for sexual incompatibility of this species. It is observed that the taxa required comparatively low sucrose concentration (5%) for their optimal in vitro pollen germination (54.08%). Boric acid to a certain extent also influences the in vitro pollen germination (56.2%). In the present investigation, the nature of substrate in association with the effect of Boric acid, CaCO3, MgSO4 on the in vitro pollen germination of Eichhornia crassipes is also worked out. However, the tested salts show no significant effect on pollen germination in the present study.
