摘要: 为探索野韭菜(Allium tuberosum)对干旱环境的响应特征,以秦岭野韭菜为试验材料,研究了干旱胁迫及复水对叶绿素相对含量和氮含量的影响。结果表明,随着土壤干旱胁迫时间的延长,秦岭野韭菜叶绿素相对含量及氮含量均呈下降低趋势,水分胁迫指数呈上升趋势。21 d干旱秦岭野韭菜叶绿素相对含量和氮含量下降幅度达到最大,较对照分别下降39.47%和30.99%。复水处理后,野韭菜叶片的叶绿素相对含量与氮含量均逐渐得到恢复。随着干旱胁迫后复水时间的延长,秦岭野韭菜叶绿素相对含量和氮含量的恢复情况有所不同,复水14 d后秦岭野韭菜叶绿素相对含量恢复到对照水平,复水5 d后秦岭野韭菜的氮含量恢复到对照水平,复水激发了秦岭野韭菜的生理补偿作用。

Abstract: Aiming to explore the response characteristics of Allium tuberosum(wild chives) to drought environment, taking Qinling wild chives as the experimental material, the study investigated the effects of drought stress and rehydration on its relative chlorophyll content and nitrogen content. The results showed that, with the extension of soil drought stress time, both the relative chlorophyll content and nitrogen content of wild chives showed a decreasing trend, while the water stress index showed an increasing trend. After 21 days of drought treatment, compared with the control group, the wild chives experienced the maximum decrease in relative chlorophyll content and nitrogen content, which decreased by 39.47% and 30.99%, respectively. After rehydration treatment, the relative chlorophyll content and nitrogen content of wild chives gradually recovered. With the extension of rehydration time after drought stress, the recovery of relative chlorophyll content and nitrogen content in wild chives was different. After 14 days of rehydration, the relative chlorophyll content of Qinling wild chives returned to the control level, and after five days of rehydration, the nitrogen content of Qinling wild chives returned to the control level. Rehydration stimulated the physiological compensation effect of wild chives.
