PEG-6000模拟干旱胁迫下油用亚麻苗期抗旱指标筛选及抗旱性评价OA
Drought Resistance Indicators Screening and Evaluation in Oil Flax Seedlings under PEG-6000-Induced Drought Stress
为筛选油用亚麻苗期抗旱性评价的关键指标并鉴定品种抗旱性,以 20 个不同来源的油用亚麻品种为材料,设 PEG-6000 溶液模拟干旱胁迫,以蒸馏水为对照,测定种子萌发及幼苗生长指标.通过主成分分析及基于 D 值的聚类分析,筛选出4 个核心抗旱指标:相对萌发指数、相对发芽指数、相对芽伸长、相对干物质转化率.聚类分析将品种分为 3 类:强抗旱型(伊亚 4 号、iran159、Egypt62、1159pi1181058)、中抗旱型(轮选 3 号、Cfresbr21101、伊亚 6 号、坝亚 6 号、Sumper sky 2dar、ty21、伊亚 3 号、JWS、Hungary244、France319、ArtenTine)和干旱敏感型(乌亚 17 号、宁亚21 号、新亚1 号、龙亚8 号、宁亚18 号).该研究为油用亚麻抗旱育种提供科学依据.
To screen key indicators for drought resistance evaluation in oil flax seedlings and identify drought-tolerant varieties,20 oil flax varieties from diverse origins were subjected to PEG-6000 solution(simulating drought stress)and distilled water(control).Seed germination and seedling growth parame-ters were measured.Through principal component analysis and D-value-based cluster analysis,four core drought resistance indicators were identified:relative germination index,relative sprouting index,relative shoot elongation,and relative dry matter transfer rate.Cluster analysis classified the varieties into three categories:strong drought resistance(Yiya 4,iran159,Egypt62,1159pi1181058),moderate drought resistance(Lunxuan 3,Cfresbr21101,Yiya 6,Baya 6,Sumper sky 2dar,ty21,Yiya 3,JWS,Hunga-ry244,France319,ArtenTine),and drought sensitivity(Wuya 17,Ningya 21,Xinya 1,Longya 8,Ningya 18).This study provides a scientific foundation for drought-resistant breeding of oil flax.
