摘要
利用电子光合测定仪，对设施栽培条件下“乍娜”、“凤凰５１”品种的光合特性进行研究，结果表明葡萄光合日变化呈现明显的双峰型，两品种光合峰值及光合低谷期长短有明显不同。在华北地区，影响设施内葡萄光合效率的主要生态因素是ＣＯ２浓度和水分状况，尤其是设施内相对湿度和光合效率有明显相关。
Study on Photosynthesis Characteristics of grape varieties“ZhaNa”and “FengHuang 51”cultivated in control installations condition was performed with electron Photosynthesis detector,the results shows that there are double peak in the daily variation of grape Photosynthesis and the photosynthesis crest value and the length of the trough period are obvious different between the two varieties. In north China area,the major ecological factors affecting the efficiency of grape Photosynthesis are CO 2 and moisture contents,especially,the relative humidity has a direct bearing on the efficiency of photosynthesis.
