再生水对作物种子萌发、幼苗生长及抗氧化系统的影响

以小麦、黄瓜、西红柿为供试材料,研究再生水水培对小麦、黄瓜和西红柿种子萌发、生长发育及其活性氧清除系统的影响.结果表明,再生水对小麦种子发芽率有明显的促进作用,对西红柿种子无显著影响,而黄瓜种子表现出一定的抑制作用;对各物种幼苗生长发育有一定促进作用,再生水灌溉对小麦、黄瓜及西红柿叶片活性氧清除系统均无不利影响;作物各叶绿素及蛋白质含量也显著高于对照.研究结果表明,再生水可以替代自来水进行作物灌溉,但灌溉过程中需采取适当的措施,使再生水利用效果最佳.

Effects of reclaimed water on seed germination, growth and antioxidant system in crops

Researches were conducted to understand the germination, the growth and the physiological characteristics of crops in response to irrigation with reclaimed water, and to assess the feasibility of using the reclaimed water as an alternative irrigation source for crops. Irrigation with reclaimed water had different effects on germinations of different materials but improved seed establishment and growth. There is no negative effect of irrigation with reclaimed water on the balance of antioxidant system of crops, while some measures must be adapt to keeping the effects of reclaimed water irrigation in optimization.
