光照强度对花叶冷水花色素含量和过氧化氢酶活性的影响
Effects of different light intensity on pigments and catalase (CAT) of Pilea cadierei Gagnep
摘要
Abstract
The present experiment was conducted to explore the light intensity factor, which impacts the anthocyanin and chlorophyll contents of Pilea cadierei, to provide theoretical basis for the scientific culturing of Pilea cadierei. [Method]The Pilea cadierei was treated under five different light intensity conditions, including highlight (Illuminance: 15000-20000 lx), normal light (500-1000 lx), shade 1 (250-500 lx), shade 2 (100-300 lx), and dark(0 lx). [ResultJThe total chlorophyll (chl.a+b) contents under shade 1 and shade 2 were higher than those tested under normal light, while the contents tested the lowest under highlight. The Chl.a/Chl.b value, at 1.57, was the lowest under full shade; on the other hand, the value tested under highlight was the highest. Anthocyanin content tested under highlight was significantly higher than that tested under other lights. Furthermore, the anthocyanin content exhibited negative correlation with the Chi. value. The CAT activities of Pilea cadierei increased under the highlight and dark light testing conditions, which exhibited remarkable differences with the CAT activities tested under normal and shade testing conditions, which indicated that the antioxidant system responded well to highlight stress. [Conclusion ]Pilea cadierei displayed strong shade tolerance; therefore, this plant could suitably survive indoor and enclosed environments.关键词
