Effects of Different Molecular-weight Glycosaminoglycan on Yield and Quality of Watermelon
摘要
Abstract
The effects of different molecular -weight glycosaminoglycan on the yield and quality of watermelon variety “Jianian-hua 2” were studied .The results showed that different molecular -weight glycosaminoglycan significantly affected the growth charac-ters, quality and yield of watermelon , and the glycosaminoglycan with middle molecular weight (100000~500000) had the most obvious effects .As compared with the control , the middle molecular-weight glycosaminoglycan significantly increased the leaf are-a, stem width and leaf chlorophyll content of watermelon plants by 3.5%, 11.4%and 19.4%respectively, enhanced the contents of soluble sugar, VC and lycopene by 20.6%, 20.6%and 10.5%separately, decreased the content of titratable acid by 16.3%, and raised the single-melon weight by 6.6%.The watermelon yield in the treatment of middle molecular -weight glycosaminogly-can reached 45858.6 kg/hm2 , which was significantly higher than that in other treatments .The treatment of 0.2%acetic acid had no significant influence on the growth , quality and yield of watermelon .Therefore, the application of middle molecular -weight gly-cosaminoglycan could increase watermelon yield significantly , improve its quality , and had good application value .关键词
