| 摘 要： | 为探索干旱胁迫对辣椒生长的影响,以不同抗旱性的辣椒品种(系)为试验材料,采用盆栽称重控水法,研究不同程度干旱胁迫对辣椒幼苗形态指标的影响.结果表明:随着水分胁迫的加剧,3种辣椒的株高、茎粗、主根长、侧根数、生物量呈下降趋势.抗旱性强的8093号在重度水分胁迫下其茎粗与株高比值大,其他各项指标的下降幅度小.

| Abstract: | The effects of various degrees of drought stress on the morphological indexes were researched by pot experiment in hot pepper seedlings with different drought resistance in the present study.The results showed that the height,stem diameter,root number,root length and biomass decreased with drought stress degree rising.Under severe drought stress,high drought-resistant cultivar(line) had the highest ratio of height to stem diameter,and the decent ranges of these indexes were small. |
