摘要:

以发光二级管(LED)为光源研究不同光质对姜黄生理特性的影响。结果表明:红光、蓝光和红蓝组合光处理均提高了姜黄素含量;红光有利于提高叶绿素a和总叶绿素含量、可溶性糖含量,蓝光有利于提高类胡萝卜素含量、SOD和POD活性、蛋白质含量,绿光有利于提高类胡萝卜素含量和蛋白质含量,黄光有利于提高蛋白质含量。红光/蓝光=7:3时姜黄的总叶绿素含量、类胡萝卜素含量、SOD活性、Fv/Fo和姜黄素含量分别比对照显著提高14.23%、23.60%、18.18%、22.60%和66.65%;说明红光/蓝光=7∶3时最适合于姜黄的生长和姜黄素的生成。

Abstract: The effects of different light qualities generated by light emitting diodes (LED) on the photosynthetic characteristics of Curcuma longa L. were studied. The results showed that red light, blue light, and combined red + blue light all increased the curcumin content. In addition, red light increased the contents of chlorophyll a, total chlorophyll and soluble sugar. The blue light benefited the contents of caroteoids and protein, the activities of superoxide dismutase (SOD) and peroxidase (POD). The green light improved the contents of caroteoids and protein, while yellow light promoted the accumulation of protein. The chlorophyll and carotenoid concentrations, SOD activities and the ratio of FvFo significantly increased by 14.23%, 23.60%, 18.18%, 22.60% and 66.65% respectively under the red/blue light=7:3 treatment, suggesting that the ratio of 7:3 was optimum for the growth and curcumin accumulation of C. longa.
