Abstract:

Ultra-drying Chinese-fir, pine and Casuarina equisetifolia seeds had higher vigor after one-year-storage in ambient temperature. When Chinese-fir seed MC was between 4 percent and 5 percent , pine seeds MC was 5 percent and Casuarina equisetifolia seeds MC was 1 percent ,its higher viability and vigor could be retained, its cell membrane integrity remained well and the activity of dehydrogenase, α-Amylase and respiration intensity were highest. So ultra-dry could improve the storability of Chinese-fir, pine and Casuarina equisetifolia seeds.

Key words: Ultra-dry storage, Seeds, Vigor, Physiological characteristic
