Following X-ray treatment of seeds ofTrigonella foenum-graecum(subject to doses of 25000, 50000 and 75000 R units besides control) plants were grown to maturity and resultant pollen grains studied. Little pollen morphological variation regarding apertural condition, shape and surface pattern have been noticed. Variations in size of pollen grains were found, viz. up to the level of 50000 R a gradual decrease in the mean polar axis and equatorial diameter of pollen grains was noted, but 75 000 R had no further effect and the dose of 100000 R proved lethal for the seeds.
