光质对三七生长、光合特性及有效成分积累的影响

为了揭示光质对三七生长、光合特性及有效成分积累的影响，该研究采用7种光质（红、橙、黄、绿、青、紫、蓝），进行盆栽试验，测定三七生长过程中其生长指标、光合特性及有效成分的含量。结果表明，光质对三七生长、光合特性及有效成分均有显著影响，其中红光有利于三七的株高生长，青、黄、紫、蓝光均有利于三七地下部分生物量的积累，蓝、黄光有利三七光合作用，青光有利于人参皂苷Rd的积累，黄、青光有利于单株三七有效成分总量的增加。

Effect of light quality on growth, photosynthesis and effective components of Panax notoginseng

In order to discover light quality's effects on growth, photosynthesis and effective components content of Panax notoginseng, a pot experiment using 7 light qualities (red, orange, yellow, green, cyan, violet, and blue) was conducted. The growth, photosynthesis and content change of effective components were measured during plant growth. The results showed that light qualities had significant effect on plant growth, red light increased the plant height, while cyan, yellow, violet, and blue lights promoted accumulation of biomass underground, blue and yellow lights increased the photosynthesis, cyan light increased accumulation of ginsenoside Rd, yellow and cyan lights increased total effective components of individual plant.
