Abstract
This study was performed during a continuous period of two years on young nectarine trees in greenhouse. Trees were trained to central leaders and planted at in-row spacing of 1m with 2m between rows. At the stage Ⅲ(fruit enlargement rapidly), different quantities of potassium fertilizer were applied to the soil as: 0 g/plant(Treatment A as control) and 100 g/plant(Treatment B) and 150 g/plant(Treatment C) and 200 g/plant(Treatment D). The results showed that: as compared with control, ferlizer-applying in three treatments all increased Leaf Intercellular CO_(2) concentration (Ci), Transpiration (Tr), Temperature of leaf (Tleaf) and Photosynthesis (Pn) ( the treatments were 4.80, 3.98, 3.56 #mu#mol/(m~(2)·s), respectively. But control was 2.10#mu#mol/(m~(2)·s) at rhe same time. When correlation coefficients between the quantity of potassium and the above parameters of photosynthesis were analyzed, it was showed that Tleaf and Ci were positively correlated to the quantity of potassium, while leaf CE (Pn/Ci) was negatively related to that. Thus, Leaf Pn was non-significantly distinct among treatment with different quantities of potassium fertilizer.
