Effect of herbicide on pollen germination and pollen tube length was studied. Glyphosate inhibited the pollen germination and pollen tube growth at higher concentrations. The percentage of pollen germination was decreased from 29.29, 23.74, 11.49, 3.94 and 0.0 at 20, 40, 60, 80 and 100 ppm of glyphosate, respectively. Similarly, the pollen tube length was also declined and which was https://www.biotech-asia.org/vol3no2/effect-of-herbicide-glyphosate-on-pollen-germination-in-vitro-and-pollen-tube-length-of-hibiscus-cannabinus-linn/ Herbicide; Glyphosate; pollen grain; Hibiscus cannabinus Linn
