Effects of Different Soil Moisture Conditions on Growth and Photosynthetic Physiological Characteristics of Cinnamomum camphora Ganning No.1
摘要
Abstract
To investigate the effects of different soil moisture levels on the growth and photosynthetic physiological charac-teristics of Cinnamomum camphora Ganning No.1(a citral-type camphor tree cultivar),three year old cuttings were used as materials.Four field capacity gradients were set:W1:(85±5)%,W2:(65±5)%,W3:(45±5)%,and W4:(15±5)%.The photosynthetic physiological characteristics and chlorophyll fluorescence parameters under different treatments were ana-lyzed.The results showed that the W2 treatment was the optimal moisture condition.Under this treatment,the increments of tree height and ground diameter,as well as the photosynthetic rate,photochemical quenching coefficient,and actual quan-tum efficiency,were the highest and significantly different from those under other treatments,while the non-photochemical quenching coefficient was the lowest.As soil moisture decreased,leaf thickness decreased,malondialdehyde content in-creased,and cell membrane damage intensified.In conclusion,(65±5)%field capacity was the suitable moisture condi-tion for maintaining efficient photosynthesis,promoting growth,and preserving membrane stability in Ganning No.1 seed-lings.This finding provides a theoretical basis for water management during the seedling stage of this cultivar.关键词
