Fruit and Seed Development of Sorbus pohuashanensis Hedl

Abstract:

Seed development traits of Sorbus pohuashanensis are discussed with special regard to embryo formation. The purpose of this research was to provide additional data for understanding embryo developmental processes and identifying the appropriate developmental stage for seed collection in S. pohuashanensis. A correlation was found between the embryo developmental stages and the time after pollination. The developmental stages cover globular, heart, torpedo and cotyledonary embryo stages within 30 days post-pollination. There were significant differences in embryo length, width and length to width ratio at different development stages. A significant negative correlation between embryo dry weight (DW) and moisture content (MC) was also observed.
