Abstract
The effects of light spectral energy distribution of light emitting diode(LED)on the growth and quality of Helianthus annuus sprouts were studied.Fluorescent light was used as the control.The results showed that,on the condition of light intensity 23 μmol·m-2·s-1,photoperiod 14 h·d-1,and temperature(25±2)℃,red light could significantly increase the cotyledon area,the hypocotyl diameter,the starch content and the chlorophyll to carotenoid ratio of sunflower sprouts.Besides,compared with other treatments,red light could improve the content of chlorophyll a,total chlorophyll and carotenoid remarkably.Blue light obviously increased the accumulated amount of dry weight,soluble protein and the activity of POD,CAT.Yellow light could inhibit the elongation of roots,and promote the accumulation of free amino acid.Under the light of ultraviolet B,hypocotyl length and the activity of SOD,CAT were improved significantly.Overall,red light was more beneficial for the culture of sunflower sprouts.
