Abstract
With an EARS--Plant photosynthesis meter we determined gross photosynthesis (P) of leaves of 'Cat Hoa Loc' mango on 4 years old trees planted in the Fruit Tree Experiment and Production Station, Campus 2, Department of Crop Science, College of Agriculture, Can Tho University in the rainy season of the year 2000. The same experiment was conducted on 'Nam Roi' pummelo on a farm located in the Binh Minh district, Vinh Long province. In the rainy season the calculated gross photosynthesis of 'Cat Hoa Loc' mango leaves at flowering stage was higher than that at the vegetative stage. However, the photosynthetically active radiation and quantum yield of 'Cat Hoa Loc' mango leaves in both stages did not reach the light saturation point when compared with values from estimated equation of photosynthetic light curve. The same holds true for 'Nam Roi' pummelo in the vegetative stage.
‘Cat Hoa Loc’芒果(Mangifera indica L.)和‘Nam Roi’柚(Citrus grandis (L.))叶片光合作用的研究奥斯贝克)在雨季。
在2000年雨季，我们用ear -植物光合作用计测定了芹托大学农学院作物科学系第二校区果树试验生产站种植的4年树龄“猫和洛”芒果叶片的光合作用(P)。在永隆省平明区的一个农场对“南莱”柚进行了同样的实验。在雨季，开花期芒果叶片的总光合作用计算值高于营养期。然而，与光合光曲线方程估算值相比，两个生育期‘Cat Hoa Loc’芒果叶片的光合有效辐射和量子产量均未达到光饱和点。这同样适用于营养阶段的“南莱”柚子。
