Mode of pollination and seed setting in Egyptian clover

Summary The average cross-pollination in Egyptian clover under caged and uncaged conditions was 0.51% and 1.44% respectively. The low percentage of cross-pollination under caged conditions was due to the absence of honey bees, calm atmosphere and reduced photosynthesis whereas higher outcrossing under uncaged conditions was both by wind and honey bees activities. Per cent seed set was higher under uncaged conditions (53.0%) compared with that of seeds set under caged conditions (26.3%) and uncaged + hand tripping (52.3%). The honey bees have been found to increase seed set in Egyptian clover by tripping mechanism.
