Phytohormonal dynamics in the abscission zone of Korla fragrant pear during calyx abscission: a visual study.

ABSTRACT:

Introduction

Phytohormones play a crucial role in regulating the abscission of plant organs and tissues.

Methods

In this study, the ultrastructure of the sepals of Korla fragrant pears was observed using a transmission electron microscope, and high-performance liquid and gas chromatography were used to analyze the dynamic changes of phytohormones in the abscission zone during the calyx abscission process of Korla fragrant pears, and mass spectrometry imaging was applied to ascertain the spatial distribution of phytohormones.

Results

The results revealed that the mitochondria in the abscission zone of the decalyx fruits were regularly distributed around the cell wall, and the chloroplasts were moderately present. In contrast, in the persistent calyx fruit, the correspo
