从2007—2009年研究了六盘山林区野生濒危植物——桃儿七种子的不同处理方法和播种季节对出苗率的影响,结果表明,种子在冬季沙藏(或雪藏)3个月以上,由于经过了一个较长的休眠期,出苗率较高且整齐;而种子在春季、秋季水浸10 d后,播种的出苗率较低且不整齐.因此,采用冬季沙藏(或雪藏)桃儿七种子的繁育方法可以在本地区大面积推广.
By using 7 different treatments and sowing seasons,the effects on seedling emergence rate of the Sinopodophyllum hexandrum(Royle),a wild endangered species in Liupanshan Mountain,were researched from 2007 to 2009.The results indicated that the emergence rate was high with an even distribution by means of sand storage or snow storage of the seeds for 3 months in winter due to a long dormancy period.Relatively,the emergence rate was low with an uneven distribution by means of water storage for ten days in spr...
