不同光照对砂仁生长影响的研究进展

Research progress on the effect of different light on the growth of Amomum villosum

摘要: 主要介绍光环境（光照强度、光质和光周期）对砂仁开花、花期、落果等生长方面的影响。光照强度达到400 μmol/(m²·s)后，砂仁光合速率趋于最大值。相对于其他光质，蓝光可以促进砂仁的生长。使用红光或者低比例的红光和远红光对植物体内的赤霉素合成具有调控作用，可为砂仁保果技术提供一个研究的方向。

Abstract: The effects of light environment (light intensity, light quality and photoperiod) on flowering, florescence and fruit drop of Amomum villosum were introduced. When the light intensity reached 400 μmol/(m²·s) , the photosynthetic rate of Amomum villosum tended to be saturated with the increase of light intensity. Compared with other light qualities, blue light promoted the growth of Amomum villosum. Red light or low proportion of red light and far-red light could regulate gibberellin synthesis in plants, which could be a research direction for fruit preservation of Amomum villosum.
