摘 要：
本文在对12种植物耐荫性研究的基础上,选择3类不同耐荫性植物紫娇花(Tulbaghia violacea)、白绢草(Tradescantia sillamontana)和金粟兰(Chloranthus spicatus)为试验材料,对其在不同光照条件下形态和光合指标的变化进行了研究,结果表明:紫娇花在透光率50%条件下生长最好,白绢草在透光率35%条件下生长最好,金粟兰在透光率15%条件下生长最好,并且3类植物都是在适度遮荫条件下净光合速率和表观量子效率值高,遮荫有利于提高阴生植物生长势和光合性能。根据3类植物在不同光照条件下形态及光合指标的相应变化,得出紫娇花耐荫性弱,较喜光,白绢草耐荫性中等,金粟兰耐荫性极强。

摘 要：
On the basis of shade-tolerance research of 12 plant species, taking3 shade-tolerance plant species(Tulbaghia violacea Harv., Tradescantia sillamontana Matuda and Chloranthus spicatus(Thunb.) Makino) as the experimental materials, a research has been carried out into the characteristics of morphology and photosynthesis under different sun-shading treatments, the results show that Tulbaghia violacea under 50% sun-shading treatment, Tradescantia sillamontana under 35% sun-shading treatment, Chloranthus spicatus under 15% sun-shading treatment grow well, and their net photosynthetic rates and apparent quantum yields reach the peak data under the moderate sun-shading treatment. The moderate shading is favorable to improve the growth and photosynthesis of shade plants. According to their changes of morphological and photosynthetic characteristics under different sun-shading treatments, Tulbaghia violacea is a low shade-tolerant plant species, and can grow well under a little shading, Tradescantia sillamontana is an intermediate shade-tolerant plant species, and Tradescantia spicatus is a strong shadetolerant plant species.
