Abstract

This study was conducted during growing season of 2022 in a private orchard of pomegranate ( Punica granatum L.) cv. Mahdawi which is located at Dulib village, Duhok Governorate, Kurdistan region to evaluate the efficacy of foliar spray of, Gibberellins (GA3) Kelatex (Ca) and Aminoplasmal (A). The experiment designed as a factorial experiment in a randomized complete block (RCBD) with three replications, for each treatment and each replicate was represented by one tree. There were three concentrations of Gibberellins (0,50 and 100mg. L -1 ); three concentration of Ca (0, 200, and 400mg. L -1 ) and three concentrations of Aminoplasmal (0, 100 and 200ml.L -1 ) in the study. The results showed that GA3 at 100mg. L -1 had a significant effect on leaf area, leaf dry weight, leaf chlorophyll content, leaf nitrogen content and leaf calcium content when compared to control. On the other hand, that Ca at 400 mg. l -1 had significant effect on leaf dry weight, leaf chlorophyll and leaf calcium content when compared to control, in addition to Aminoplasmal at 200 mg. L -1 had significantly affected leaf area, leaf dry weight, chlorophyll content, nitrogen content, and calcium content. Furthermore, the interaction between (GA3, Ca and A) had significant effect on leaf chlorophyll, leaf calcium content, leaf nitrogen content, and leaf area at concentrations of (100, 400, and 200 mg. L -1 ) respectively. However, the leaf dry weight was significantly affected at concentrations of (100,200 and 200 mg. L -1 ) respectively.
叶面喷施赤霉素、Kelatex和aminoplasms对石榴树营养生长和叶片养分的影响简历。Mahdawi
本研究于2022年生长季在一个石榴(Punica granatum L.)私人果园进行。位于库尔德斯坦地区杜胡克省Duhok村的Mahdawi,以评估叶面喷雾、赤霉素(GA3)、Kelatex (Ca)和Aminoplasmal (A)的效果。实验设计为随机完全区(RCBD)的析因实验,每个处理有三个重复,每个重复用一棵树表示。赤霉素浓度分别为0、50、100mg。L -1);三种浓度的Ca(0,200和400mg)。L -1)和三种浓度的氨基浆(0,100和200ml)。L -1)。结果表明,GA3在100mg时;与对照相比,L -1对叶片面积、叶片干重、叶片叶绿素含量、叶片氮含量和叶片钙含量均有显著影响。另一方面,钙是400毫克。l -1对叶片干重、叶片叶绿素和叶片钙含量均有显著影响。L -1对叶面积、干重、叶绿素含量、氮含量和钙含量影响显著。此外,在100、400和200 mg浓度下,(GA3、Ca和A)互作对叶片叶绿素、叶片钙含量、叶片氮含量和叶片面积均有显著影响。L -1)。100,200和200 mg浓度对叶片干重有显著影响。L -1)。
