Abstract

Abstract:

Seeds of Picea asperata were dried from 82 g·kg^-1 to 64，52，41 and 29 g·kg^-1 moisture content in a desiccator with silica gel. After the desiccation, seed vigor and physiological indices, including seed germination energy, germination percentage, germination index, relative conductivity, dehydrogenase activity and isocitrate lyase activity were measured. The results showed that the seeds had high desiccation tolerance.When dried to 41 g·kg^-1，the seeds still had stable viability，the relatively integral cell membrane structure，the high dehydrogenase and isocitrate lyase activities.To some extent, the seed kept genetic stability by artificial aging test.

Key words: Picea asperata, seeds, ultra-drying storage, physiological and biochemical characteristics
