EFFECT OF SOME CHEMICAL COMPOUNDS ON SOME CHARACTERISTICS OF SHOOT AND FRUIT OF PEACH (Prunus persica L.) CV. EARLY CORONET
This study was carried out during 2008 growing season on peach trees (Prunus persica L.) cv. Early Coronet selected from orchard in Seiujh - Duhok city - Kurdistan Region, Iraq, to investigate the effect of [Naphthalene acetic acid [NAA, Riedel-de Haen (0 and 5 mg.l-1); KNO3 (Merck) (0, 0.1 and 0.2...

| Summary: | This study was carried out during 2008 growing season on peach trees (Prunus persica L.) cv. Early Coronet selected from orchard in Seiujh - Duhok city - Kurdistan Region, Iraq, to investigate the effect of [Naphthalene acetic acid [NAA, Riedel-de Haen (0 and 5 mg.l-1); KNO3 (Merck) (0, 0.1 and 0.2 %), and Fe (NaFeEDDHA) Technical Sodium Ferric ethylenediamine di-o-hydroxyphenyle acetate (0, 30 and 60 mg.l-1] on growth and fruit characteristics. One month after fruit set, trees were sprayed at two date (24/April/2008 and 25/May/2008) with NAA, KNO3 and Fe. Raising the levels of NAA to 5 mg.l-1, KNO3 to 0.2 % and Fe to 60 mg.l-1 led to a significant increase in the value of shoot dry weight, total chlorophyll, fruit number, fruit length, fruit diameter, total carotene as compared with untreated trees. The interaction between Foliar spray of 5 mg.l-1 NAA 0.2% KNO3 60 mg.l-1 Fe were the best treatment which gave the highest means of shoot dry weight, total chlorophyll, fruit number, fruit length, fruit diameter and total carotene. |
