Abstract
The effects of different ratios of Red [R,(658±20) nm]/Far-red [Fr,(715±20) nm] and Red/Blue [B,(460±20) nm] generated by light emitting diodes (LED) on growth of chrysanthemum (Dendranthema morifolium) plantlets in vitro were studied. As the results showed,red LED promoted the growth of chrysanthemum plant-lets and increased root length,contrary to far-red LED and blue LED. Carotenoid content was negatively related to R/Fr ratios. The contents of chlorophyll a,chlorophyll b,chlorophyll (a+b) and carotenoid were also nega-tively related to R/B ratios. Chlorophyll a/b ratios were correlated with R/B and R/Fr ratios positively. Red LED promoted the accumulation of soluble sugar and starch,but decreased pigment contents. On the contrary,blue LED enhanced the synthesis of pigment contents and soluble proteins. Both the contents of soluble sugar,starch in leaves and the root activity were higher under the complex light of red and blue LED than those under the fluorescent light. Especially,the plantlets grew more stronger and the highest survival rate of transplanted plantlets were observed under the light of high R/B ratio.
