不同光环境对胡桃楸幼苗生物量及光合生理的影响
Effect of Different Light Environment on Biomass andPhotosynthetic Physiology of Juglan mandshurica Seedling
摘要
Abstract
In order to study the different light environment on Juglan mandshruica seedling biomass and photosynthetic physiology and analyze the response on different light environment,the growth,biomass and photosynthetic physiology were studied under three light environments(100％,60％,30％ light).The results showed that there were significant differences in the growth of Juglan mandshruica seedling under different light environment,and the ground and underground biomass and photosynthetic physiology were different.Under low light conditions,Juglan mandshruica seedling grew fast,plant height and ground diameter were 1.14 and 1.18 times of full light conditions.There were significant differences in aboveground biomass under three kinds of light conditions,and no significant differences in the underground part.Light response parameters were different under different light conditions,and net photosynthetic rate increased with light intensity.Juglan mandshruica seedling have made adaptive adjustment in growth and physiological aspects to response to different light environment,and appropriate shading is more conducive to the growth of seedlings.关键词
