为了提高罗蜜红(Roumi Red)葡萄(Vitis vinifera L.)的座果率和产量,进行了叶面喷施和土壤灌注PP_333试验。100和250ppm(叶施)及2毫升/株(土施)的处理,对叶绿素和类葫萝卜素含量及浆果的理化特性均无影响。但是,果穗重及每穗的果粒数都有显著增加。1000,1500和2000ppm及4毫升/株的处理,降低了新梢及节间长度,也减少了浆果的含糖量,但增强了浆果的理化性质和芽子的生殖能力,也提高了叶
In order to improve fruit yield and yield of Roumi Red grape (Vitis vinifera L.), foliar application and soil perfusion PP_333 were conducted. The treatments of 100 and 250 ppm (leaf application) and 2 ml / plant (soil application) had no effect on the content of chlorophyll and carotenoids and physico-chemical properties of berries. However, both the ear weight and the number of fruit per panicle increased significantly. The treatments of 1000, 1500 and 2000 ppm and 4 ml / plant reduced shoot and internode length and decreased berry sugar content, but enhanced physico-chemical properties of berry and reproductive capacity of shoots and also increased leaf
