| 摘 要： | 以大田栽植的燕红、燕山短枝等5个板栗品种4a生树为试材，在土壤干旱条件下测定了净光合速率、蒸腾速率、WUE等指标。结果表明，5个品种净光合速率、蒸腾速率等7个指标的日变化规律有所不同，日平均值有明显差异；依据光合相关指标的差异性，分析了各品种的耐旱力，结果表明，燕红、燕山短枝、后84-3耐旱性强，达1-3耐旱能力较差，燕昌极不耐旱。

| Abstract: | Five chestnut varieties (4 - year - old) were taken as the research materials. And their net photo-synthetic rate (Pn) , water using efficiency ( WUE ) , etc, were determined. The results showed that the daily variation patterns of seven photosynthetic indices such as Pn of the varieties were different, and their daily means were significantly different. Thereafter, drought resistance of the five varieties were analysed. It is concluded that the varieties of Yanhong, Hou84 - 3, Yanshanduanzhi performed highly resistant to drought followed by Dal - 3 and Yanchang. |
