Consequently, due to the partially observed different effects of leaf removal and berry thinning, it was concluded that investigating the effects of these treatments on some yield, quality, and canopy microclimate characteristics considering the timing and method of treatments together with varieties and changing climate characteristics would be beneficial.

Abstract

In viticulture, growing techniques affect fruit quality and yield, depending on environmental conditions and the characteristics of varieties. In this study, the effects of leaf removal (LR1(ABS), LR1(V), LR2(BF/ABS), and LR2(BF/V)) and berry thinning (BT) treatments (BT(+) and BT(-)) in the Prima early table grape variety were examined. Leaf removal treatments at different periods in shoots increased cluster width (LR1(V) and LR2(BF/ABS)) and cluster size (LR1(V)). In terms of berry characteristics, no significant effect of leaf removal was determined. Berry color index (CIRG) values were higher in the LR2(BF/ABS) and LR2(BF/V) treatments compared to the single-period leaf removal treatments (LR1(ABS), BT(-), LR1(ABS), BT(+), LR1(V), BT(-), LR1(V), BT(+)). It was observed that performing leaf removal once at the berry set (LR1(ABS)) increased acidity content, while performing it at the veraison (LR1(V)) raised pH and maturity index values. While Photosystem II (PSII) and SPAD values of leaves in the leaf removal treatments were found similar, the highest PSII value of lateral shoot leaves was found in the LR1(V) treatment. Berry thinning at the rate of 1/3 in the cluster significantly increased cluster width, cluster homogeneity, berry length, 100-berry weight, and CIRG values compared to the control plants. Consequently, due to the partially observed different effects of leaf removal and berry thinning, it was concluded that investigating the effects of these treatments on some yield, quality, and canopy microclimate characteristics considering the timing and method of treatments together with varieties and changing climate characteristics would be beneficial.
