Variations Analysis of Sugarcane Stalk Fiber Components and Mechanical Properties in Progeny of Saccharum robustum Reciprocal Crosses
摘要
Abstract
In order to explore the relationship between sugarcane fiber components and sugarcane stem mechanics,24 sugarcane germplasms derived from reciprocal crosses of Saccharum robustum were used as materials.The contents of cellulose,hemicellulose and lignin were determined using high-performance liquid chromatography(HPLC)and ultraviolet spectrophotometry,respectively.Meanwhile,the stalk-breaking force near the ground end was measured using a stalk strength tester,followed by variance analysis and correlation analysis.The results of variance analysis revealed significant differences in cellulose,hemicellulose,and lignin contents among the 24 sugarcane germplasms,as well as significant variations in the stalk-breaking force near the ground end.The contents of cellulose,hemicellulose and lignin ranged from 27.50%-43.51%,13.14%-23.62%and 12.38%-25.02%,respectively.Correlation analysis revealed that the stalk-breaking force exhibited a highly significant positive correlation with cellulose and hemicellulose contents,while showing a positive correlation with both acid-soluble lignin and acid-insoluble lignin contents.The mechanical properties of the tested germplasms stalks near the ground end were primarily determined by the cellulose and hemicellulose contents.Screening S.robustum germplasms with high fiber components could provide an excellent germplasm foundation for developing breakthrough sugarcane varieties with enhanced lodging resistance and pest resistance.关键词
