| 摘 要： | 研究了温室内不同品种山茶(Camellia japonica L.) 的光合特性。结果表明不同品种山茶的光合特性相似: 光补偿点在6. 7～8. 4μmol·m-2·s -1 之间; 光饱和光强300μmol·m-2·s-1左右; 最大光饱和光合速率4. 1～4. 8μmol·m-2·s -1 ; 表观量子效率0. 055～0. 075 ; 羧化效率0. 03～0. 04 ; 光合作用的适宜温度在15～25 ℃。据此推测山茶不喜强光, 也不耐高温, 认为山茶正常生长所需要的光照强度应控制在300μmol·m-2·s -1 左右, 温度应控制在15～25 ℃之间。

| Abstract: | Photosynthetic characteristics , including chlorophyll content , soluble protein content and carboxylation efficiency , in different cultivars of Camellia japonica , and the influences of light intensity and temperature on photosynthesis of the cultivars were studied. The results showed that photosynthesis in differentcultivars of Camellia japonica were similar : Light compensation point is between 6. 7 - 8. 4μmol·m-2·s -1 , light saturation point is arroud 300μmol·m-2·s -1, maximal light saturation photosynthetic rate is between 4. 1-4. 8μmol·m-2·s-1 , apparent quantity yield is between 0. 055 - 0. 075 CO2/ photon, Carboxylation efficiency is between 0. 03 - 0. 04 μmol·m-2·s -1 , proper temperature was between 15 - 25 ℃. Therefore , they were susceptible to higher light intensity and temperature. For that , during the cultivation and attendance to Camellia japonica L , both light intensity and temperature should be proper to meet with the needs of growth and development of different cultivars of Camellia japonica. |
