Abstract
Changes in oil, protein, carbohydrate, fiber, ash and gossypol contents of cottonseed during germination were studied. Highest reduction in kernel dry weight and highest oil, protein and carbohydrate consumptions occurred after the 8th day. Percentage carbohydrate consumption was always higher than oil or protein consumptions. Only little changes in fatty acid composition of oil was detected even during most rapid loss from kernels. The rate of losses of the three major fatty acids from kernels were in the following order: linoleic>oleic>palmitic. There was a continuous increase in the percentage total phospholipids as germination proceeds. The lecithinβcephalin ratio was 1:1.5 up to 10 days germination, after which the ratio was lowered. The data indicate significant changes in the fatty acid constitution of the phospholipids throughout the germination period.

## Abstract The processes associated with pollen germination were studied in vitro for two tree species, __Salix caprea__ and __Fraxinus excelsior__ under different nutrient conditions. The results provide evidence of changes in chemical composition of the pollen grains during germination. From the
