摘  要:
用不同浓度的2-(3,4-二氯苯氧基)-乙基-二乙胺(DCPTA)对四季豆浸种,研究DCPTA对四季豆苗期生长的影响。结果表明,DCPTA促进了四季豆幼苗的植株生长,株高和根长都比对照明显提高,在DCPTA处理浓度为0.6 mL/L时均达到最大值,株高比对照提高15.78%,根长比对照提高18.30%。同时,DCPTA浸种提高了四季豆幼苗的叶绿素含量和根系活力,降低了四季豆幼苗的丙二醛(MDA)含量,当处理浓度为0.6mL/L时,四季豆幼苗中叶绿素含量比对照提高了19.65%,根系活力比对照提高了11.78%,MDA含量比对照降低了26.53%。DCPTA浸种处理能够促进四季豆幼苗的生长,且在浓度为0.6 mL/L时最合适。

摘  要:
The effects of DCPTA on the seedling growth of kidney bean were studied by soaking the seeds in different concentration solutions of DCPTA.Significant effects were observed when the concentration of DCPTA was 0.6 mL/L.Compared with the control,the content of chlorophyll in seedling leaves of kidney bean increased by 19.65%;the plant height,root length and root vitality increased by 15.78%,18.30% and 11.78% respectively,while the content of MDA decreased by the rate of 26.53%.In conclusion,it would promote the seedling growth if soaking the kidney bean seeds with DCPTA,and the most suitable concentration was 0.6 mL/L.
