Phytohormonal dynamics in the abscission zone of Korla fragrant pear during calyx abscission: a visual study
IntroductionPhytohormones play a crucial role in regulating the abscission of plant organs and tissues.MethodsIn this study, here 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
