中文摘要 | 本研究的目的在於探討不同整枝處理(水平整枝與V型整枝)對茄子葉片光合成能力之影響。試驗結果顯示茄子冠層的透光率,以V型整枝處理的株冠層較薄,葉層排列緊密,對光截取能力較佳。不同葉位的光合成速率,不同處理間均以盛花下第一片葉的光合成速率最高,其次依序為盛花上第一片葉、盛花下第三、五及七片葉。不同時期單葉光合成速率則以在5月27日生育初期之V型整枝處理可達17.48 µmol CO2/m2/s,而對照之水平整枝處理僅為16.48 µmol CO2/m2/s;但在8月27日生育中期,V型整枝處理因棚架遮蔭效應之故,僅為15.90 µmol CO2/m2/s,而以水平整枝處理18.37 µmol CO2/m2/s的表現較佳。不同整枝處理間,日變化情形均以上午9~11 點為一日中光合成速率的最高峰。 |
英文摘要 | The purpose of this research was to assess the influence of different training (H-and V-type)on photosynthetic rate of eggplant leaves. Results indicated that the light transmission of eggplant canopy in V-type training had thinner leaf layer and higher light interception than H-type training. The net photosynthetic rate was the highest at full blooming stage on lower 1 leaf followed by upper 1 leaf, lower 3, 5 and 7 leaf. The net photosynthetic rate of each leaf in H-type training detected at the early growth stage on May 27, was 16.48 µmol CO2/m2/s which is lower than the V-type of 17.48 µmol CO2/m2/s. At the mid growth stage on August 27, the net photosynthesis rate of H-type was 18.37 µmol CO2/m2/s which is higher than that of V-type at 15.90 µmol CO2/m2/s. The highest level of photosynthesis rate appeared at 9~11 AM. in both training treatment. |
