Cressa cretica L. belonging to family Convolvulaceae, commonly known as Boknu is a erect, small,
dwarf shrub, usually grows in sandy or muddy saline habitats. Brew baker and Kwack's basal
medium was used for germination of pollen grains. At low concentration (5% and 10%) of water
extract of Cressa cretica plant (WEC) reported minimum inhibitory effect i.e., 57.84% 42.78%
respectively on in vitro pollen germination of Cajanus cajan. The maximum reduced pollen
germination was observed under 75% concentration of leaf extract (8.69%) and pollens were no
germinated on 100% of WEC as compared to control (70%) after 15 minutes. The aerial parts of
Cressa cretica L. yielded five flavonoids that were identified.
