Measurement on Brix and Juice Extraction Rate of Local Sweet Sorghum Varieties in Changshu City
摘要
Abstract
Brix and juice extraction rate are important economic traits of sweet sorghum.Identifying local sweet sorghum germplasm resources,exploring the dynamic variation patterns of brix and juice extraction rate in different internodes of the same plant at different growth stages,and simultaneously screening elite local varieties will boost the development of the sweet sorghum industry.In this study,five local sweet sorghum varieties from Changshu City,Jiangsu Province were used as experimental materials to conduct spatiotemporal analyses of their brix and juice extraction rate.Highly significant differences in brix were observed among different stem nodes of the same plant for each sweet sorghum variety,and both brix and juice extraction rate showed a trend of being high in the middle and low at both ends.The correlation coefficients between brix and juice extraction rate of the same stem node were 0.691 for Zhitang Luji and 0.895 for Dongbang Tianlu,both reaching significant levels(P<0.05).Highly significant differences were detected in single-plant stem weight,juice yield,juice extraction rate and brix among different varieties(P<0.01).Zhitang Shiyue Lu exhibited the highest per-plant stem biomass,juice yield and juice extraction rate,but the lowest brix.The whole-plant brix of Dongbang Tianlu reached 16.4%,ranking the highest among all varieties.One month after physiological maturity,the juice extraction rate of all five local varieties decreased extremely significantly(P<0.01).The brix of Dongbang Tianlu declined extremely significantly(P<0.01),while the brix of Zhitang Shiyue Lu and Meili Luji increased significantly(P<0.05)and extremely significantly(P<0.01),respectively.关键词
