Abstract: The grape variety ‘Pione (Vitis labrusca × Vitis labrusca) was used in this experiment under substrate (peat∶compost∶vermiculite=4∶1∶1, V/V) culture, and soil culture was taken as the control. Physical and chemical characters of ‘Pione grape under different substrates and its effects on vine growth, phenology and berry quality of ‘Pione grapes were investigated. The results were shown as follows: There is no difference between substrate and soil culture in phenology, chlorophyll content and berry size. Compared with soil, grape cultivated in substrate has smaller leaf area. Substrate improved the color of berries, though the TSS and firmness of flesh was little lower than in soil. It could be related with the high vibration frequency of water content in substrate and the unstable absorbance of nutrition by roots. Its suggested that the integrated management of fertilization and irrigation should be applied to solve these problems.
