Abstract
The effects of different light qualities generated by light emitting diodes(LED) on growth and physiological characteristics of cucumber seedlings were studied.Eight treatments were designed with red LED(R),blue LED(B) and the complex light of red and blue LED(R/B=9∶1,8∶2,7∶3,6∶4,5∶5),compared to the treatment of white fluorescent light(CK).The results showed that the cucumber seedlings had a bad growth status under only red or blue LED.The growth under the complex light of red and blue LED was better.Red LED promoted the accumulation of soluble sugar.On the contrary,blue LED enhanced the synthesis of soluble proteins.The specific leaf weight,chlorophyll contents reached the highest in R/B=7∶3 LED,which were significantly higher than that of the control.It was suggested that R/B=7∶3 LED was suitable for the growth of cucumber seedlings.
