摘要:
以3个品种的茶花(Camellia)为研究对象,经过3个不同的遮阴(全光照,20%,60%)处理后,测定叶绿素含量、可溶性糖、可溶性蛋白以及游离脯氨酸等生理指标。结果表明:遮阴处理后,叶绿素a、叶绿素b以及叶绿素总量含量增加;而可溶性糖则表现为20%遮阴度>60%遮阴度>全光照;可溶性蛋白与游离脯氨酸在3个品系各遮阴处理之间表现不同。综上表现:20%遮阴度下更适合茶花的生长,香茶花的耐阴性强于其他2种茶花。

Effects of the Physiological Indices in Three Varieties of Camellia by Different Shade Treatments
Huang Yongfang
Abstract:
Taking three varieties of Camellia as the research object, the chlorophyll (Chl) content, soluble sugar, soluble protein and free proline were determined under three different shade treatments (CK, 20%, 60%). The results showed that with the increase of shade degree, the contents of Chl a, Chl b and the total Chl were increased. The soluble sugar was 20% shade> 60% shade>CK; The soluble protein and free proline of the varieties of Camellia under the shade treatment had expressed different. The results were that 20% shade was more suitable for the growth of the Camellia, the shade tolerance of the C. incense was stronger than the others
