DIFFERENT PRUNING APPLICATIONS ON PISTACHIO AND ALMOND

A pruning experiment was performed on Kirmizi pistachio nut and Nonpareil and 101–9 almonds.
Summer pruning was performed in August on pistachio nut and in July and August on almond.
Autumn pruning was applied in November on pistachio nut and in October on almond.
The effects of these treatments on flowering, shoot development, fruit yield and quality were compared with those of winter pruning.
Summer pruning caused a 2–3 day delay of flowering in Nonpareil and a 3–6 day delay in 101–9. Shoot development was better in July-pruned almonds.
In pistachio nut, autumn and winter pruning induced poor shoot development.
However, fruit drop was observed on poorly developing one year old shoots which resulted in a high rate of fruit set.
This self-thinning decreased the rate of alternate bearing and a regular crop was obtained the following year.
Additionally, the splitting rate and fruit size were increased.
Autumn pruning in November caused increased shoot development and a decrease in fruit bud drop.
