Light, as a critical environmental factor, plays pivotal role in photosynthesis, ultimately influencing the timing of bud flush tea plants. However, synergistic effects different photoperiods and light qualities on albino cultivar ‘HuangKui’ (later germination variety) remain unknown. Thus, objective this study was to investigate (12L/12D, 14L/10D, 16L/8D, 18L/6D, where L = number daylight hours D darkness) ratios red (R) blue (B) (R/B 1:1, R/B 1:2, 1:3, 2:1) growth variety ‘HuangKui’. In our study, we examined how affected by investigating flush, chlorophyll content, indicators. First, showed that germinated 4 days, 2 1 day earlier under 16L/8D photoperiod at one leaf period compared with plants cultivated 12L/12D, 18L/6D simulating solar spectrum. Also, maximumly promoted treatment. Additionally, earliest observed for 2:1 (red/blue) treatment other treatments. Moreover, greatest plant height, length new shoots, areas were detected 2:1. contents auxin (indole acetic acid, IAA) trans-zeatin (tZ) significantly higher than those 1:1 control treatments photoperiod. auxin-related expression levels CsIAA13, CsGH3.1, CsAUX1, CsARF2 control. The CsARR-B, positive regulator cytokinin-related genes, treatment, while opposite result found negative CsARR-A. Therefore, an appropriate means ‘HuangKui’, which may be related IAA or tZ signal transduction. conclusion, research offers novel lighting strategy promotes cultivars.
