Effects of Cerasus humilis (Bge). Sok. Rootstock on Peach Growth, Development, and Expression of Growth-Related Genes

Peach trees play an essential role as economic crop in China. However, the increasing cost of labor has led to a decline benefits peach cultivation. The use dwarfing rootstock technology can increase planting density, reduce tree height, decrease requirements, and production costs. Cerasus humilis (Bge). Sok. is promising for peaches owing its small size, abundant resources, strong resistance, adaptability. In this study, we investigated effect rootstocks on growth development, related gene expression. We used Ruipan 4/Cerasus 4/Amygdalus persica L. experimental materials measure fruiting characteristics two-year-old rootstocks. addition, bioinformatic methods explore Our results showed that dwarf trees, branches, pollen count stigma receptivity, shorten spore promote protein accumulation late stage fruit maturity. reduced hormone content while upregulating expression growth-related PpYucca5 PpYucca2 genes. PpYucca6 was downregulated early shoot upregulated middle stage. By reducing hormones, be dwarfed, but their impact quality minimal. These indicate suitable provide theoretical reference future breeding
