摘　　要：辣椒的生长发育过程对水分的需求较高,为研究干旱对辣椒生长发育的影响,设计了正常水分(CK)、轻度胁迫(A处理)、中度胁迫(B处理)和重度胁迫(C处理)4个处理,分析不同干旱胁迫程度对辣椒生长发育及光合效应的影响。结果显示,随着干旱程度的加深,辣椒的生长及其产量各指标显著下降。其中,株高、株幅、果实纵径、果实横径、单果鲜质量和单株产量由高到低依次为CK>A处理>B处理>C处理。此外,叶绿素含量及净光合速率也呈现相似的下降趋势,4个处理的叶绿素a含量、叶绿素b含量、类胡萝卜素含量和净光合速率由高到低分别为CK>A处理>B处理>C处理。结果表明,干旱胁迫对辣椒生长发育和光合作用呈显著负效应,建议在干旱季节采取适当的灌溉措施以保障产量和品质。In order to study the effects of drought on the growth and development of Capsicum annuum,four treatments were designed to analyze the effects of different drought stress levels on the growth and development of Capsicum annuum and photosynthesis.The results showed that the growth and yield of Capsicum annuum decreased significantly with the deepening of drought.The results showed that drought stress had a significant negative effect on the growth and photosynthesis of Capsicum annuum.It was suggested that appropriate irrigation measures should be taken in the dry season to ensure the yield and quality.
