Seed Size Effects on Germination, Survival and Seedling Growth of Castanea sativa Mill.

Emrah Cicek and Fahrettin Tilki
The effects of seed size on seed germination, and seedling survival and growth of Castanea sativa were studied in this study. The seeds were classified into small (< 5 g), medium (5-8 g) and large (> 8 g) classes. Germination parameters were significantly related to seed weight and large seeds germinated early and showed better germination than small seeds under laboratory conditions. Survival percentage and various morphological traits of the seedlings were investigated at the end of first growing season in nursery bed. It was found that seed size significantly affected seedling emergence, seedling survival, shoot height, root collar diameter and seedling dry weight but did not significantly affect shoot/root ratio and the average numbers of roots. Thus, it can be concluded that large seeds in C. sativa have better germination and survival, and the larger the seed, the larger the average seedling would be in seedling diameter, height and dry weight.
