摘要: 研究在不同光照条件下(光强分别为自然光的8%、15%、35%、42%、50%及75%)生长的茶树扦插苗的光合作用,叶绿素含量和生长情况。结果表明:茶树扦插苗的光合速率(Pn)、最大光合速率(Pnmax)、表观量子效率(AQY)均在自然光强的75%时达到最大值; 叶绿素含量随光强的增加而降低,叶绿素a/b则随光强增加而增加; 新生物量与最大光合速率一致,在自然光强的75%时达到最大值; 其植株生根率、出现愈伤组织的比率、根条比及根生物量比(RMR)随光强的增加而增加,死亡率、SLA及LAR随光强的增加而降低。根据实验结果,适当提高大棚透光率及在阴天对大棚中的茶苗进行加光处理,对快速繁育茶苗有利。

Abstract: The photosynthesis, chlorophyll content and the growth traits of the clone tea seedling grown under different light conditions (8%, 15%, 35%, 42%, 50% and 75% ambient light) under the greenhouse were compared. The photosynthetic rate (Pn), maximum photosynthetic rate (Pnmax), apparent quantum yield (AQY) and new biomass reached their maximum values at 75% ambient light condition. The content of chlorophyll, death rate, specific leaf area (SLA) and leaf area ratio (LAR) decreased with the increase of light intensity, while the ratio of chlorophyll a/b, root emerging rate of the plant, traumatic tissue formation rate, root shoot ratio (R/S) and root mass ratio (RMR) increased as the light intensity increased. 50% and 75% ambient light were beneficial for the fast seedling-breeding to increase the light transmissivity of the green house and improve the light intensity for the seedling in the tents during cloudy days.

Key words: Camellia sinensis, greenhouse seedling-raising, light intensity, photosynthesis, growth analysis
