- 摘要:
- 采用随机区组试验设计,用生根粉药剂对层积处理后经过催芽处理的北五味子种子进行浸泡处理,播种后对北五味子幼苗行测量调查。结果表明:经过生根粉药剂处理后的北五味子种子长出的幼苗在根、茎、叶等各项生理特征均优于CK,其中根长比CK增加了30.30%,侧根数目增加了50%,主根直径增加了22.5%,芽的数目平均增加了2.8个;幼苗植株叶绿素含量第5、6、7叶位比CK分别高19.22%、39.23%和19.07%,并且提前达到了一定的高度,进入有机物的积累时期,为第2年的良好生长提供了保证。
- Abstract:
- An investigation was conducted to measure the seedlings of Schisandra chinensis (Turcz.) Baill. after planting the seeds,which were soaked in ABT after stratification and accelerated germination with the application of randomized block experimental design.The results showed that the physiological characteristics of the seedlings of Schisandra chinensis(Turcz.) Baill. was better than those under conventional cultivation (CK) in the respects of root,stem,and leaf after the seeds were soaked in ABT,among them the roots,compared with those under conventional cultivation (CK),increased 30.30%,the number of taproots 22.5%,and the number of sprouts 28 on average.The contents of chlorophyll of seedlings at the fifth,sixth and seventh leaf positions risen 19.22%,39.23% and 19.07 respectively and reached certain heights earlier to enter the accumulation stage,which provided a guarantee for the healthy growth in the next year.
