通过大田栽培试验,探讨生育后期不同遮荫处理(遮荫率0、30%、50%和70%)对罗汉果净光合速率和罗汉果品质的影响。经过遮荫处理,罗汉果净光合速率日变化曲线由对照组(遮荫率为0)的双峰型转变为单峰型,曲线峰值出现在中午12:00时。遮荫率50%处理的曲线峰值、罗汉果苷Ⅴ含量和干果重比其它遮荫处理和对照组的高。结果表明,在桂南种植的罗汉果,生育后期给予遮荫率50%的处理对增加罗汉果的净光合速率,提高罗汉果苷Ⅴ含量和干果重较为有利。
通過大田栽培試驗,探討生育後期不同遮蔭處理(遮蔭率0、30%、50%和70%)對囉漢果淨光閤速率和囉漢果品質的影響。經過遮蔭處理,囉漢果淨光閤速率日變化麯線由對照組(遮蔭率為0)的雙峰型轉變為單峰型,麯線峰值齣現在中午12:00時。遮蔭率50%處理的麯線峰值、囉漢果苷Ⅴ含量和榦果重比其它遮蔭處理和對照組的高。結果錶明,在桂南種植的囉漢果,生育後期給予遮蔭率50%的處理對增加囉漢果的淨光閤速率,提高囉漢果苷Ⅴ含量和榦果重較為有利。

Different shading treatments(shading rate 0,30%,50% and 70%)were used to study the influence on net photosynthetic rate and quality of Siraitia grosvenorii at the late growth stage through the field conditions.The diur-nal variation of net photosynthetic rate varied from a bimodal curve under control group(shading rate 0)to a unimodal one under shading condition and curve peak value appeared at 12:00 noon.Curve peak value,the content of mogrosideⅤand dried fruit weight under the treatment of 50% shading rate were higher than those under the treatments of other shading rates .The results showed that at the late growth stage of S.grosvenorii cultivated in south Guangxi, the treatment of 50%shading rate increased net photosynthetic rate,and it was good for dried fruit weight and impro-ving the content of mogrosideⅤ.
