Abstract
Four-year-old Campbell Early grape vines cultured in pots were used for the experiments. In mid March, slaked lime was applied to half the number of vines and sublimed sulfer to the remaining halve for the adjustment of soil acidity (pH) to high and low levels. Half of each set of lime or sulfur applied vines was top-dressed with superphosphate early in May. After that an amount of copper sulfate was applied to the soil of all pots, each set of vines with or without superphosphate was further divided into two treatments; half of vines were kept under water-saturated soil conditions by flooding the pots with water from late July to induce the vein-yellowing of leaves and the remaining halves were provided with adequate moisture.1. The range of soil pH before the flooding treatment was 6.3-6.7 in the lime applied pots and 2.4-2.6 in the sulfur applied pots, respectively. Further, the available phosphoric acid content in soil was higher in the former than in the latter, and was increased by the superphosphate top-dressing. The contents of Cu in soil exchangeable with N/5 KCl were just reciprocal to those of available phosporic acid in these treatments.2. The flooding treatment lowered the contents of N, K and Mg in the leaves of the basal part of shoots irrespective of the lime or sulfur application and the superphosphate top-dressing. The sap pH of the leaves was not affected by any of the treatments.3. Vein-yellowing of basal leaves, detected only in the flooding treatment, was depressed by the superphosphate top-dressing and more notable in the lower soil pH condition than in the higher one. Further, the vines receiving both lime and superphosphate did not exhibit the vein-yellowing presumably caused by the excess of soluble copper in the soil even under circumstances which were suitable for the occurrence of the disorder.
