The effect of different light conditions on the Cyclobalanopsis blakei(Skan)Schott. container seedling growth and physiology
Abstract：Cyclobalanopsis blakei (Skan) Schott.is an evergreen tree, a more limited distribution, are extremely endangered species, and because of the artificial destruction has drastically declined. As a evergreen species, hard materials, better contraction, a wide range of applications. In this paper, Cyclobalanopsis blakei(Skan)Schott. container seedlings for the study, research different light conditions on the container seedling growth and physiological impact. After preliminary research, Cyclobalanopsis blakei(Skan)Schott. container seedlings different lighting conditions will appear different reactions, light intensity, the stronger, the faster the speed of its container seedlings under the light of the growth of seedlings height, stem diameter, leaf span is greater than under the shade of seedlings; leaf water content determination found that, under normal light leaf water content percentage is significantly higher than under shade conditions leaves, and leaf area and leaf dry weight measured by calculating the ratio leaf weight more important than leaf blades under normal light significantly greater than the shade leaf Weight; Determination of chlorophyll content, leaf chlorophyll content analysis of shade container seedlings chlorophyll content lower than normal lighting conditions, indicating light stronger, the higher the content of chlorophyll; electron transfer rate will increase with the increase of the light intensity, and the maximum electron transfer rate of the normal lighting container seedlings electron transport rate should be higher than the shade. The results of this study is to further develop the growth of physiological experiments of Cyclobalanopsis blakei(Skan)Schott. container seedlings, seedling cultivation and ex-situ conservation has laid the foundation for further protect seedlings and introduction and domestication of expansion, beech, oak sub provenance characteristics provides a theoretical foundation.
