Abstract

This study was conducted in the growing season of 2021 at the Agricultural Research Facility Station, University of Basrah. Start with seedlings of two genera of ornamental palm trees: Washingtonia filifera and Phoenix canariensis. Were given dosages of humic acid as treatment (0, 10, and 15 ml.L-1). And fulvic acid by ground addition at concentrations of (0, 5, and 10 g.L-1). The findings revealed that humic acids significantly impacted the anatomical traits and caused the improvement of those traits. The Humic acid content of (15 ml.L-1) caused an increase in the thickness of epidermal cells, the length of columnar cells, the diameter of large and small vascular bundles, and the diameter of the fibrous bundles. Additionally, a level of fulvic acid (10 g.L-1)caused a similar increase in those anatomical traits. The triple interaction significantly impacted the qualities under study. The interaction between the Washington type, the (15 ml.L-1) of humic acid, and the (10 g.L-1) of fulvic acid provided the highest values. For the anatomical traits, the thickness of epidermal cells, length of Columnar epithelial cells, the diameter of large and small vascular bundles, and diameter of large and small vascular bundles. And the diameter of the fibrous bundles. Washingtonia palm was significantly higher than the canary palm and had the highest values for epidermal cell thickness, columnar cell length, large and small vascular bundle diameter, and fibrous bundle diameter. Keywords: ornamental trees; humic substances;leaves; anatomical; fulvic acid; seedling

腐殖酸和富勒酸处理对华盛顿棕榈（Washingtonia filifera）和加纳利凤凰（Phoenix canariensis）两属观赏棕榈幼苗叶片解剖特征的影响

这项研究于 2021 年生长季节在巴士拉大学农业研究设施站进行。从两种观赏棕榈树属的幼苗开始：Washingtonia filifera 和 Phoenix canariensis。分别给予腐殖酸剂量（0、10 和 15 ml.L-1）。富里酸的地面添加浓度为（0、5 和 10 g.L-1）。研究结果表明，腐植酸对解剖学性状有明显影响，并能改善这些性状。腐植酸含量为（15 ml.L-1）时，表皮细胞厚度、柱状细胞长度、大小维管束直径和纤维束直径都有所增加。三者之间的相互作用对所研究的质量产生了重大影响。华盛顿类型、腐殖酸（15 ml.L-1）和富里酸（10 g.L-1）之间的相互作用产生了最高值。在解剖学特征方面，表皮细胞厚度、柱状上皮细胞长度、大小维管束直径、大小维管束直径。纤维束直径。华盛顿棕的表皮细胞厚度、柱状上皮细胞长度、大小维管束直径和纤维束直径的数值均明显高于金丝雀棕，且金丝雀棕的表皮细胞厚度、柱状上皮细胞长度、大小维管束直径和纤维束直径的数值最高。
