Taking ‘Cabernet Sauvignon’,‘Cabernet Gernischt’ and ‘Merlot’ three varieties of wine grape as materials,the effect of different loads on fruit quality were studied.The results showed with the decrease of the load,fruit grain diameter,weight and soluble solids content were increased,but the change of titratable acid content was not changed obviously by the decreasing of the load.It concluded that 60% load treatment was the best.
