通过β-氨基丁酸激发效应增强烟草对干旱和低温胁迫的耐受能力
Priming effect of β-aminobutyric acid in alleviating drought and low-temperature stress in tobacco
摘要
Abstract
In order to study the effect of exogenous BABA (β-aminobutyric acid) on alleviating low temperature and drought stress,tobacco seedlings were treated with different concentrations of BABA by spraying leaves and filling roots,and followed by drought and low temperature stress.After that,the survival rate of the tobacco seedlings was measured.The results showed that the survival rate of the tobacco seedlings was significantly increased when spraying the leaf with 5 mmol·L-1 and irrigating the root with 10 mmol.L-1 exogenous BABA,respectively,regardless of drought stress or low temperature stress.The results demonstrated that exogenous BABA can effectively improve the tolerance of tobacco seedlings to drought and low temperature stress.关键词
