摘要
用IDS法处理樟子松（PinusSylvestrisvar,mongolica）种子，发现死种子较活种子拥有较高的含水率．干燥过程中，死种子水分散失速度比活种子快，在干燥到8～10h进行分离可清除27％左右的种粒，使下沉种子的发芽率和活力指数分别从75％和4．39提高到91％和5．85，并且拥有较高的抗低温损伤和高温老化能力。
After IDS treatment moisture contents of dead seeds of Pinus Sylvestris Var. mongolica higher than did Liveseeds. When desication proceeded of 25℃, the dead seeds lost imbieed water at a much faster rate than did Liveseeds. The seeds of 27 % were separted after 8 to 10 hour of drying,the germination percentage and vigor index ofthe bottom seeds rose foom 75% and 4. 39(Control) to as high as about 91 % and 5. 85,the surface fraction (deadand dying seeds) usually had a significantly higher index of ageing and chilling injury percent.
