Morphological Differentiation Process of Flower Buds and Nutritional and Physiological Characteristics in Leaves of Choerospondias axillaris

【Objective】This study aims to explore the corresponding relationship between external morphological changes and anatomical structures in the differentiation process of Choerospondias axillaris flower buds, and reveal the relationship between the dynamic changes of nutrients in leaves and the differentiation process of flower buds.【Method】The paraffin section method was used to observe the flower buds of C. axillaris, and the contents of soluble protein, soluble starch, soluble sugar, total phosphorus, total nitrogen, total potassium, and organic matter in the leaves near the bud were determined at key differentiation stages.【Result】1) The flower type of C. axillaris was thyrse or solitary, with the male flower as inflorescence, and the female flower as inflorescence or solitary. Most of the flower buds of C. axillaris were mixed buds, with a sprouting rate of 99% for adult male trees and 70% for female trees. 2) The differentiation of C. axillaris flower buds can be divided into 9 stages: undifferentiated sta
