Effect of Substrate Water Content on Survival Rate,Growth and Electrophysiological of Camellia olei f era Seedlings
摘要
Abstract
To study the effect of substrate water content on seedlings survival rate and growth physiology ,one-year-old seedlings of Camelliaoleifera (Fengyang No .1) were chosen as experimental materials ,which were grown in six substrates of different water content by weigh-ting method (CK ,T1 ,T2 ,T3 ,T4 and T5) .The results showed that :When the substrate water content less than 81% ,the survival rate of seedlings began to decline ,and with the increase of drought stress time ,the survival rate was also decreased .When substrate water content was 90%-81% ,the growth of shoots and new leaves ,leaf size were the largest and the value were 5 . 21cm ,4 .89 ,4 .23cm × 2 .43cm respectively .By contrast ,the biomass were largest (fresh weight was 7 .92g and dry weight was 3 .44g) ,and the ratio of root/shoot was the smallest (fresh ratio was 0 .4 and dry ratio was 0 .47) .We could knew that substrate resistance is mainly determined by the leaf water content was 100%-91% .from the stepwise regression analysis result .The re-sistance of the various parts were minimum (new leaves> old leaves> substrate) and the water content of leaf was the largest (68 .5% ) .关键词
