干旱胁迫对西克刺桐花芽分化的生理特性影响OA
Physiological Characteristics of Flower Bud Differentiation in Erythrina sykesii under Drought Stress
为了研究干旱胁迫诱导西克刺桐Erythrina sykesii花芽分化的生理特性,以其 8 年生植株为材料,测定干旱胁迫下叶片光合色素、可溶性糖、丙二醛、内源激素含量和超氧化物歧化酶、过氧化物酶活性等生理指标,分析西克刺桐对干旱胁迫的生理响应及其成花诱导特性.结果表明,随着干旱胁迫程度增加,西克刺桐叶片光合色素、抗氧化酶活性和内源激素含量均呈先增后降的变化趋势;轻度干旱胁迫时叶片叶绿素和类胡萝卜素、淀粉、可溶性糖、IAA、GA3和ZR含量达到最大…查看全部>>
In order to explore the physiological characteristics of drought stress-induced flower bud differentiation in Erythrina sykesii,the physiological response of E.sykesii to drought stress and its flowering induction characteristics were analyzed.The physiological indicators such as the contents of photosynthetic pigments,soluble sugar,malondialdehyde and endogenous hormones,and the activities of superoxide dismutase(SOD)and peroxidase(POD)in the leaves of 8-ye…查看全部>>
