大麦种质资源苗期抗旱性评价
Evaluation of Drought Resistance in Barley Germplasm Resources at Seedling Stage
摘要
Abstract
Drought is a significant abiotic stress factor affecting the growth and development of barley.As a critical stage in barley growth,drought stress at the seedling stage directly impacts later growth.This paper utilized 302 cultivated barley varieties as materials,identifying drought resistance at the seedling stage,clarifying drought resistance indicators,and screening germplasm resources with excellent comprehensive drought resistance performance.The results indicate that root length,root-shoot ratio,leaf area,dry matter content,plant height,relative leaf water content and chlorophyll content can all serve as drought resistance evaluation indicators for barley seedlings.Among these,root length has high reliability as a single indicator for assessing drought resistance at seedling stage.Through comprehensive drought resistance evaluation,16 highly drought-resistant varieties were selected,including P5,P240,P162,P74,P238,P87,P226,P144,P20,P29,P64,P287,P80,P95,P81 and P114.关键词
