LED红光处理对牡丹试管苗生根及其酶活性的影响
The effect of LED red light on rooting and related enzyme activity of Paeonia suffruticosa plantlet in vitro
摘要
Abstract
The effect of different treating time of LED red light on rooting and related enzyme activity of Paeonia suffruticosa plantlet in vitro with cultivar of “Tai ping hong” was studied, and the different treating time of LED red light were6 ( Ⅰ ), 9 (Ⅱ), 12 (Ⅲ), 15 (Ⅳ) days. The results showed that, the tendency of the index of the peony tube seedlings including rooting rate, rooting index, the average root length increased then decreased, along with the increase of treating time of the LED red light. And the index of the peony tube seedlings of Ⅱ including rooting rate, rooting index, the average root length was the best. The rooting rate of the CK reached minimum. After a span of treatment under the LED red light, it was found that the activity of POD decreased then increased, the activity of PPO decreased, increased then decreased, and the activity of IAAO increased then decreased. While,the activity of POD increased, decreased then increased, the activity of PPO decreased, and the activity of IAAO increased in control. The tendency of these enzyme activities was significantly different from the control.关键词
