Development of adventitious roots is crucial for successful tea propagation, yet it is often inhibited by low temperatures in winter. To enhance tea rooting efficiency during winter, we investigated the effects of different shade treatments (different colors and shade levels) on the root development of Camellia sinensis cv. Longjing 43. Blue and red nets with 95% shade percentage achieved the highest rooting rates (> 95%) and longer roots, followed by silvery and black nets at 55% shading, while the 95% black net showed the poorest performance. The underlying mechanisms were investigated using transcriptome and phytohormone profiles through weighted gene co-expression network analysis (WGCNA) and KEGG analysis. The results showed blue net shading primarily affected zeatin metabolism, and red net shading promoted indole-3-acetic acid (IAA) metabolism, both of which regulated hormone signaling and hormone composition. Relevant key genes significantly correlated with zeatin and IAA levels were identified using Mantel tests. These findings provide a practical and cost-effective strategy to improve the winter rooting efficiency of tea cuttings under cold conditions by optimizing field growth environments.
