THE EFFECT OF LIQUID ORGANIC FERTILIZER AND SPRAY BY GIBBERELLIC ACID AND ANTI TRANSPIRATION (STRESS RELIEF) IN SOME VEGETATIVE GROWTH CHARACTERISTIC OF APPLE SEEDLING C.V ANNA

Abstract

The research was Carried out in the apple orchard belong to the Department of Horticulture Science and Landscap Design - college of Agriculture - Baghdad University during the seasons of 2013 and 2014, A factorial experiment carried out by three factors according to the randomized complete block design RCBD to study the effect of three levels of organic fertilizer Com Sol (0, 5, 10 ml.L-1) , and three levels of Gibberellic acid (0, 50.100 mg.L-1), and three levels of anti-transpiration Stress relief (0, 1.5 0.3 ml.L-1), in some growth characterestic of Apple seedlings c.v Anna. Treatments was replicated four times , the means separation were preformed via least significant difference procedures at p ≤ 0.05 . The result indecat that Com Sol , Gibberellic acid and Stress relief significantly increased shoot leangh , leaves area , leaves number and shoot number, thebinary interaction between the factors (C2G2 , C2S2 , G2S2) significantly increasedgrowth characteristic, triple interaction between the factors (C2G2S2) significantly increased growth characteristic and gave the highest results .
