Quantification and Comparative Analysis of the Phenotypic and Mechanical Characteristics of Rice Straw from Diversified Varieties

Year: 2026

Type: preprint

Abstract: A total of 368 rice straw samples featuring different subspecies (indica and japonica), growing seasons (early, middle, and late seasons), and growing locations (paddy land and upland) were collected and subjected to determine phenotypic (diameter, thickness, and area) and mechanical characteristics (shear, bending, and tensile). The principal component analysis and correlations analysis of these characteristics were examined. Results showed that the phenotypic and mechanical characteristics were inversely related to each other. The samples with superior mechanical characteristics were selected based on their interquartile ranges to further study the genetic differences. The characteristics quantified in this study can help to provide suggestions on the improvement of lodging resistance and rice cultivation.
