1. Morphological condition, carbohydrate metabolism, and germinative capacity of the beech nuts before and during storage are monitored methodically.

2. The germinative response of the coat-depleted spores to adenosine and several analogues thereof was found qualitatively similar to that obtained with intact spores.

3. In general, Binucleate pollen, in which the germinative cell has not divided into sperm when the pollen is shed, is less active metabolically during dispersal and remains viable longer than
