Pollen grains of Phoenix dactylifera were exposed to different doses of gamma radiation (250,500,1000 rad and 1 M rad). To access the effect of radiation on the external morphology of the pollen grains, they were examined with SEM after each treatment. In addition the differential thermal analysis technique was used to elucidate the stability of the chemical composition of the pollen wall to gamma radiation. A portion of the treated pollen was- used to pollinate different inflorescences of two female palm trees. The pollen grains that were exposed to y -radiation doses of 250,500 rad were morphologically similar, but showed differences in thermal behaviour. Poll...
