The present investigation was carried out in private orchard at Khatatba region, Monoufia Governorate, on 2vyears old Anna apple trees budded on two rootstocks (Mains domestics and Maling Morton 106) during the two successive seasons (2001-2002 and 2002-2003). The aim of this research was to study the effect of bending and girdling on fruit set, spurs and shoots number, leaf area, dry matter % and fruit characters. in addition to the endogenous ABA, lAA, total carbohydrates 96, nitrogen and cm ratio. The results indicated that all investigated treatments except those concerning girdling young shoots on mid-April gave significant increment in frurt set %, spurs number, leaf area, dry matter 9%, fruit weight, volume, diameter and length, TSS%, total carbohydrates %, CIN ratio, ABA, tea and reduction in frurt firmness, acidity 96 and total nitrogen over the control in the 1st and 2nd seasons. Bending on first November treatment of Anna apple trees budded on Malus rootstock and girdling old shoots on mid-March treatment of the some trees onto MM 106 rootstock significantly gave the highest increase of fruit set %, spurs number, leaf area, dry matter %, fruit weight, volume, diameter and length, total soluble solids (TSS %) and total carbohydrates %, C/N ratio, ABA and IAA, while gave significant decrease in fruit firmness, acidity, leaf N content in the ist and 2nd seasons. Chemical analysis of the treated trees by bending shoots of Anna apple budded on Malus rootstock on first November and girdling old shoots of Anna apple trees budded on MM 106 rootstock on mid-March revealed that higher contents of total carbohydrates 96, cm ratio, abscisic acid and indole acetic acid, besrde low of total nitrogen % may be in favor of spurs formation. Bending on first November of apple shoots budded on Malus rootstock and girdling old shoots on mid-March of Anna apple trees budded on MM. 106 rootstock treatments could be recommended as regard the above mentioned results.
