| 摘 要： | 目的]研究盆栽葡萄的光合特性。方法]以夏黑和绯红盆栽葡萄为试材,在室内阳台对夏黑葡萄光合速率日变化,不同叶位、不同品种、不同叶龄光合速率进行测定,同时测定节间长度和叶面积。结果]不同叶位叶片的净光合速率不相同,中间叶位的光合速率最高,不同节位的节间长度和叶片的净光合速率相关性不大,但叶面积和净光合速率相关度较高,室内盆栽葡萄的净光合速率日变化呈单峰曲线,叶龄不同净光合速率也不一样,叶龄在32 d时净光合速率最高,夏黑和绯红葡萄品种光合速率差异不明显。结论]该研究可为今后盆栽葡萄的高产优质栽培提供理论依据。

| Abstract: | Objective] To study the photosynthetic characteristics of potted grape.Method] Taking Xiahei and Feihong grape varieties as test materials,the diurnal variation of photosynthetic rate,and the photosynthetic rate in different leaf positions,different varieties,and with different leaf age were measured at indoor balcony.The internode length and leaf area were also determined.Result] The photosynthetic rate at different position leaves was not the same,the photosynthetic rate of mid-position leaf was the highest.internode length and photosynthetic rate of different position leaf were not significantly related,but leaf area and photosynthetic rate were highly related,the diurnal variation of photosynthetic rate of the indoor potted grape showed a single peak curve,different leaf age had different photosynthetic rate,leaf age of 32 days had the highest photosynthetic rate,there was no significant difference in photosynthetic rate between Xiahei and Feihong grape varieties.Conclusion] The study provides theoretical basis for the high yield and high quality cultivation of potted grapes. |
