Investigating the Mechanisms of Adventitious Root Formation in Semi-Tender Cuttings of <i>Prunus mume</i>: Phenotypic, Phytohormone, and Transcriptomic Insights.

ABSTRACT: Mei (Prunus mume Sieb. et Zucc.) is a rare woody species that flowers in winter, yet its large-scale propagation is limited by the variable ability of cuttings to form adventitious roots (ARs). In this study, two cultivars were compared: P. mume 'Xiangxue Gongfen' (GF), which roots readily, and P. mume 'Zhusha Wanzhaoshui' (ZS), which is more recalcitrant. Detailed anatomical observations revealed that following cutting, the basal region expanded within 7 days, callus tissues had appeared by 14 days, and AR primordia emerged between 28 and 35 days. Notably, compared to the recalcitrant cultivar ZS, the experimental cultivar GF exhibited significantly enhanced callus tissue formation and AR primordia differentiation. Physiological analyses showed that the initial IAA co
