EFFECT OF WAYS OF HAND THINNING ON ANNA APPLE FRUIT QUALITY AND VEGETATIVE GROWTH UNDER EGYPTIAN DESERT CONDITIONS

Abstract
Thinning is essential for producing 'Anna' apple fruits of high quality. Various ways of hand thinning were practical on fruitlets at the age of two weeks from full bloom by either leaving two or three fruitlets per cluster all over the tree or removing all fruitlets from the upper two limbs of each tree and leaving three only per cluster on the lower two limbs. The results reveal production of bigger fruits by all treatments, however best results concerning fruit weight, size and dimensions were obtained when all fruitlets were thinned from the upper two limbs and 3/ cluster left on the other two. Both firmness and T.S.S. were not changed significantly by any of the conducted treatments_ Concerning effect of thinning on vegetative growth (number of shoots, average length of new shoots and total shoot length) produced during the current year were evidently increased by thinning. However, the results were insignificant except the average length of a single shoot which increased significantly.
