不同外源根系挥发物对杉木响应低磷胁迫的影响机理
1 Regulation mechanism of different exogenous root exudates on response of Chinese fir to low phosphorus stress
[目的]为深入探究植物根系挥发性有机化合物对植物响应胁迫的影响,明确不同外源根系挥发物对杉木响应低磷胁迫的影响机理。[方法]本研究以耐低磷M25号杉木无性系为材料,进行不同磷浓度下不同外源挥发物(丁香酸和 1-丁烯)处理,并对处理后杉木幼苗根系总长度、表面积、体积、直径、SOD、POD 等指标进行检测,同时对幼苗地上部分叶绿素、Fv:Fm等光合指标进行检测,并对地上部分和地下部分磷含量、磷累积量以及磷利用效率进行分析,利用蛋白组学方法对不同处理中…查看全部>>
[Objective]In order to investigate the effects of volatile organic compounds in plant roots on plant response to stress,the regulatory mechanism of different exogenous root volatiles on Chinese fir's response to low phosphorus stress was clarified.[Methods]In this study,the clones of M25 Chinese fir with low phosphorus tolerance were treated with different exogenous volatiles(syringic acid and 1-butene)at different phosphorus concentrations.The total root le…查看全部>>
