外源激素对红锥叶片生理特性的影响
Effects of Exogenous Hormones on Physiological Characteristics of Castanopsis hystrix Leaves
摘要
Abstract
In order to investigate effects of exogenous hormones on physiological characteristics of Castanopsis hystrix leaves and to provide theoretical basis for hormonal regulation of flower bud differentiation in C.hystrix,taking three-year-old C.hystrix grafted seedlings as experimental materials,L9(3)⁴ orthogonal experimental de-sign was applied to implement foliar spray experiment with different concentration combinations of four exoge-nous hormones(6-BA,GA3,ABA and IAA).During flower bud differentiation period(from October 2022 to February 2023),leaf physiological and mineral element indexes were determined.Results showed that exoge-nous hormones exerted stage-specific regulatory effects on physiological indexes and mineral element accumu-lation in C.hystrix leaves.Most indexes showed regular changing trends.ABA and 6-BA were dominant factors affecting physiological indexes of C.hystrix leaves,and combination of 100 mg/L ABA and 200 mg/L 6-BA ex-hibited optimal promoting effect on these physiological indexes.关键词
