Abstract:

It was carried out to understand the effect of different light spectrum on the growth and quality of Helianthus annuus sprouts in artificial light plant factory.Green light(B+G),red light(B+R),far red light(B+Fr)and ultraviolet light(B+UV)with the same light intensity were added on the basis of blue light with the light intensity of 200 μmol/(m2·s).Blue LED was taken as the control.The results showed that the hypocotyl length of Helianthus annuus sprouts under B+Fr treatment increased significantly compared with the control.B+R treatment greatly improved the hypocotyl diameter,root length and fresh and dry weight of Helianthus annuus sprouts.Light quality treatments also affected the quality indexes of Helianthus annuus sprouts.Compared with the control,the content of soluble sugar,soluble protein and flavonoids of Helianthus annuus sprouts under B+G treatment increased significantly,increased by 28.78%,72.65% and 163.32% respectively.B+UV treatment significantly increased the content of total phenol,vitamin C,chlorophyll a and carotenoid by 25.81%,238.10%,12.50% and 150.00%,respectively.B+Fr treatment was beneficial to increase the content of volatile aromatic substances in Helianthus annuus sprouts,such as C6H10O,C10H16 and C10H14.In conclusion,B+R promotes the growth of Helianthus annuus sprouts,while B+G light improves the quality of Helianthus annuus sprouts.
