Abstract:

This article used Shuijing and Shenhong mature Chinese bayberry trees as test materials,and set up different laser spectra (660 nm red light and 450 nm blue light) with red to blue light quality ratios of 9∶0,9∶3,and 0∶9 for supplementary lighting. The fruit quality and nutrient composition indicators of the two varieties under different treatments are determined with no supplementary lighting as the control. The results showed that red light treatment significantly (p<0.05) increased the contents of soluble solids,total anthocyanins,and amino acids in the fruits of two varieties,and significantly reduced the content of malic acid in Shenhong Chinese bayberry fruit during the color transition period. The red blue mixed light treatment (9∶3) significantly increased the total flavonoid and total phenolic content of Shenhong Chinese bayberry fruit,but had no significant effect on Shuijing Chinese bayberry fruit. In summary,laser supplementary lighting can effectively improve fruit quality of Chinese bayberry and is a technology worth researching and promoting to improve the quality of Chinese bayberry. However,different light qualities have variety dependence,and in actual production,it is necessary to adjust the light quality ratio reasonably and accurately for supplementary lighting.

Key words: Chinese bayberry, variety, laser supplementary lighting, fruit quality, red to blue light quality ratio
