title: Studies on the physiology of pollen and pollen tube growth. 1. pinus roxburghii.
abstract: Pollen grains and pollen tubes of Pinus roxburghii were subjected to histochemical technique with a view to determining the distributional pattern of reserve substances (ascorbic acid, proteins starch, polysaccharides, nucleic acids) and some enzymes (acid phosphatase, glucose-6-phosphatase, peroxidase, esterase, cytochrome oxidase, succinate dehydrogenase). An attempt is made to correlate the activity of different enzymes in relation to pollen tube growth.
