摘要
采用1∶500,1∶1 000,1∶2 000的烟水和干馏液处理栝楼种子,研究其对栝楼种子萌发和幼苗生长的影响。研究结果表明,不同浓度烟水和干馏液处理后,栝楼种子萌发率、萌发势和萌发指数这3项指标均显著增加,且1∶2 000浓度处理增加幅度较大。随烟水和干馏液处理浓度的降低,栝楼种子α-淀粉酶活性升高;SOD活性无显著性变化;1∶2 000浓度烟水和干馏液处理后,POD活性显著升高;CAT活性表现出显著的低浓度升高而高浓度降低的趋势;1∶1 000和1∶2 000浓度的烟水和干馏液处理显著促进栝楼幼苗的生长;随着烟水和干馏液浓度增加,叶绿素含量逐渐降低,但仍旧高于对照组。研究结果证实1∶2 000浓度的烟水和干馏液可以促进栝楼种子萌发和幼苗生长,这为探索栝楼种子催芽技术提供了参考资料。
Smoke water and distillation liquid were used to treat the seeds of Trichosathes kirilowii and to study the effects of smoke water and distillation liquid on the seed germination and seedling growth of T. kirilowii. The results showed that germination rate,germination index and germination vigor of T. kirilowii all were significantly improved with the treatment of SW and DL treatment. The activity of α-amylase were significantly increased with the treatment of SW and DL at 1∶ 2 000. SW and DL treatment showed no significant effects on the activity of SOD. The activity of POD were markedly enhanced under the treatment of SW（ 1 ∶ 000） and DL（ 1∶ 2 000）. CAT activity were increased with the treatment of SW and DL at 1∶ 2 000 while were inhibited by SW and DL at 1∶ 500.Seedling height and root length were increased with the treatment of SW and DL（ 1∶ 1 000,1∶ 2 000）. SW and DL treaments improved the content of chlorophyll,and moreover with the concentration of SW and DL,the stimulatory were also increased. This work demonstrated that smoke water and diatillation liquid at 1∶ 2 000 could stimulate the seed germination and seedling growth of T. kirilowii,and it provided the references for the study of seed germination technology.
