Abstract

Abstract In 2022, researchers at the College of Agriculture, University of Anbar, studied the effects of triacontanol foliar spraying at 0, 25, 50, and 100 mg L -1 (T0, T1, T2 and T3 respectively) and ground humic acid addition at 0, 25, and 50 ml L -1 (H0, H1 and H2 respectively) on various aspects of CV. Le-conte pear seedlings’ vegetative and root growth. T3 treatment resulted in the highest rate of increase in plant height (35.50 cm), root length (20.55 cm), number of branches (7.44 branch seedling -1 ), number of lateral roots (5.33 root seedling -1 ) and chlorophyll content (109.32 mg gm -1 fresh weight), among other treatments. The results demonstrated that there were significant differences between the treatments. When treated with water (50 ml L -1 ), humic acid significantly outperformed other treatments in terms of plant height (35.17 cm), root length (20.08 cm), number of lateral roots (5.03), number of lateral branches (8.66 branch seedlings -1 ), and chlorophyll content in leaves (108.35 mg gm -1 fresh weight), according to the study. However, T 3 H 2 therapy was superior in every attribute examined when the two research parameters were considered together.
