Study on Effects of New Fungal Activator Protein on Physiological Characteristics of Pea Seedlings

摘要

摘要: 为探讨真菌源激活蛋白在促进植物生长和增产方面的作用机理,研究了不同浓度激活蛋白处理对豌豆幼苗生理特性的影响。结果表明,经1、2、5μg/mL激活蛋白处理后第7d,豌豆幼苗根系活力比对照分别增加了46.0%、58.5%和21.0%,硝酸还原酶活性比对照分别增加64.38%、140.62%和35.31%;处理后第15d,植物叶片叶绿素含量比对照分别增加了13.69%、18.49%和6.16%,可溶性糖含量比对照分别增加20.68%、32.03%和17.28%,可溶性蛋白含量比对照分别增加18.59%、32.05%和22.10%。不同浓度激活蛋白均能促进与植物生长相关的生理指标的提高,其中以2μg/mL的作用效果最好。

Abstract: In order to approach the mechanism of enhancing plant growth by new fungal activator protein,the influence of activator protein with different concentration on physiological characteristics of pea seedlings was studied.Compared with control after 7 d treatment with 1,2 and 5 μg/mL activator protein,root activity of pea seedlings was increased by 46.0%,58.5%and 21.0%,and nitrate reductase activity was increased by 64.38%,140.62%and 35.31%,respectively.Compared with control after(15 d) treatment with 1,2 and 5 μg/mL activator protein,the content of chlorophyll in leaves was increased by 13.69%,18.49%and 6.16%,the content of soluble sugar was increased by(20.68%),(32.03%) and 17.28%,and the content of soluble protein was increased by 18.59%,32.05%and(22.10%),respectively. In conclusion,after plants were treated with activator protein of different concentration,the physiological indexes related to plant growth were all enhanced in different degree,and the effect of 2 μg/mL activator protein was of best efficiency to the plant.
