Abstract

 

Cucumber (Cucumis sativus cv Delstar) was grown in greenhouse under different light-emitting diode (LEDs) to investigate the effects of different light waves on yield forms. Three treatments (red, Blue, and White) were conduct from 4 March 2008 to 24 June 2008. Results showed that, Blue light treatment got highest marketable production and marketable fruit ratio per plant, the value was 2309 g and 0.81 per plant, respectively. White treatment got lowest marketable production and marketable fruit ratio, with the value 1898 g and 0.12 per plant, respectively. However, White light treatment got highest single fruit weight with the value 166.99 g per fruit. From the above result, it may be of a good choice to use supplemental Blue light to increase cucumber production.

 

Key words: Cucumber, different light-emitting diode (LEDs), greenhouse, yield.
