Partially degraded pollen of Arenga pinnata, Borassus flabellifer and Caryota urens were studied with an object to observe the morphological changes. Degradation was achieved in the three sets of experiments. In the first experiment pollen were treated with 2-aminoethanol for a period(s) of 1, 2 and 3 days. This treatment was followed by oxidation of pollen with the help of 1% dil. KMnO^j for a period of 24 hours. This constituted the second experiment. In the third experiment pollen grains treated with 2-aminoethanol were kept in merkaptoethanol for 24 hours. Pollen were treated with 50% glycerine for 30 days to study the nature of exine, intine and protoplasmic contents. Based on the features observed after these experiments, four groups were identified in the studied pollen grains. These are: A - unchanged monosulcate pollen grains, B - open pollen grains with endexine and protoplasm contained within the pollen, C - open pollen with ectexine and without endexine and protoplasm and D - the endexine and protoplasm without the ectexine. Statistical data of pollen constituting each group has been represented in the Text-fig. 10.1. Alteration and variation in morphology of the studied pollen have been discussed.
