摘要: 以‘弗雷’和‘金手指’葡萄为试材进行喷施钛肥试验,了解钛肥对其生理和光合特性的影响以及钛肥适宜的施用浓度。结果表明:喷施钛肥能够显著提高葡萄叶片中的淀粉含量、POD活性、色素含量、净光合速率(Pn)、蒸腾速率(E)和气孔导度(C)。‘弗雷’和‘金手指’2个品种在可溶性糖、淀粉含量、色素含量、抗氧化酶活性及光合特性等指标上存在显著差异,且对不同浓度钛肥处理的响应不一致。综合各指标以及隶属函数分析认为,喷施钛肥有利于改善葡萄的生理及光合特性,‘弗雷’品种适宜喷施的浓度为2 200倍液,‘金手指’为700倍液。

Abstract: ‘Frey’ and ‘Golden Finger’ grapes were sprayed with titanium fertilizer in the experiment to test effects of the fertilizer on physiological and photosynthetic characteristics of the grapes, and to find out appropriate concentration of titanium fertilizer applied for the grapes. The results showed that starch content, POD activity, pigment content, net photosynthetic rate (Pn), transpiration rate (E) and stomatal conductance (C) of the leaves were increased significantly.There were significant differences between ‘Frey’ and ‘Golden Finger’ in aspect of soluble sugar, starch content, pigment content, antioxidant enzyme activities and photosynthetic characteristics. The two cultivars didn’ t have the same response to the treatment of titanium fertilizer with different concentrations. The comprehensive analysis of the indexes and the membership function showed that the application of titanium fertilizer was beneficial to improve physiological and photosynthetic characteristics of the grapes, and dilution with water in 2 200 times was the suitable concentration of the fertilizer for ‘Frey’ and that in 700 times for ‘Golden Finger’ .
