Abstract

The present study was conducted to evaluate the effect of different growing mediums {sand, peat moss, and mix (sand + peat moss 1:1 v/v)} and spraying with 0,100 and 150 mg L-1 of humic acid on vegetative and root parameters of “Wonderful” pomegranate hardwood cuttings at Bakrejo nursery station, Sulaimania city, Iraq in 2021. They were planted in polyethylene black bags on 15-3-2021. Using randomized complete block design within the factorial experiments with three blocks. The results indicated that leaves, roots and shoots number, root wet weight, and root length were increased significantly in peat moss medium. Cuttings grown in a mixed medium showed a significant increase of leaf growth including leaf area, leaf dry weight, and chlorophyll content. In addition, spraying with 100 mgL-1 of humic acid caused a significant increase in the root characteristics, and shoot number compared to the control. Furthermore, the maximum root growth was recorded in the interaction between peat moss medium and applying 100 mgL-1 of humic acid compared to other treatments

叶面施用腐植酸和不同生长介质对神奇石榴扦插的影响

本研究于2021年在伊拉克苏莱马尼亚市Bakrejo苗圃站，评价了不同生长介质{砂、泥炭苔藓和混合(砂+泥炭苔藓1:1 v/v)}和施用0,100和150 mg L-1腐植酸对“奇妙”石榴硬木插枝营养和根系参数的影响。它们于2021年3月15日被种植在聚乙烯黑色袋子里。在三组的析因试验中采用随机完全区组设计。结果表明，在泥炭苔藓培养基中，叶片、根冠数、根湿重和根长均显著增加。在混合培养基中生长的插条叶片生长显著增加，包括叶面积、叶干重和叶绿素含量。另外，与对照相比，施用100 mg -1的腐植酸可显著提高根系特征和芽数。此外，与其他处理相比，施用100 mg -1腐植酸的泥炭苔藓培养基的根系生长最大
