摘 要：
通过遮阴处理,研究不同透光率(15%,50%,100%)对14个川山茶品种(花洋红、白洋片、川玛瑙、胭脂鳞、紫金冠、金顶大红、七心红、川牡丹茶、石榴茶、醉杨妃、重庆红、怒春红、茶睡莲和帅旗)幼苗生长发育及生理特性的影响。结果表明,供试14种川山茶品种均有一定的耐阴性,在遮阴环境中生长良好,具有较强的适应能力。适度的遮阴对川山茶幼苗叶片叶绿素的积累具有一定促进作用,使叶片中可溶性糖含量降低,可溶性蛋白含量增加;遮阴处理对不同的川山茶品种叶片的酶活性系统影响不同,可能与川山茶品种对于光照强度的耐受性有关。其中,花洋红、川玛瑙、醉杨妃、重庆红、茶睡莲、帅旗幼苗在全光照条件下长势最佳,可进一步研究其在高温高光环境中的适应性。

摘 要：
The effects of light transmittance degrees(15%,50%,100%) on the growth and physiological traits of Sichuan Camellia such as‘Huayanghong'‘Baiyangpian'‘Chuanmanao'‘Yanzhilin'‘Zijinguan'‘Jindingdahong'‘Qixinhong'‘Chuanmudancha'‘Shiliucha'‘Zuiyangfei'‘Chongqinghong'‘Nuchunhong'‘Chashuilian'and‘Shuaiqi'were examined. The results indicated that all the cultivated varieties had adaptability to shading condition,and they grew well in the shade environment. Moderate shading could promote the accumulation of chlorophyll in the seedling leaves,make the soluble sugar content decrease,the soluble protein content increase; Shading treatments had different effects on the enzyme activities of different varieties,which might be related to their tolerance to light intensity. Among them,such varieties as‘Huayanghong'‘Chuanmanao'‘Zuiyangfei'‘Chongqinghong'‘Chashuilian'and‘Shuaiqi'grew best under full light,and their adaptability in high temperature and high light environment should be further studied.
