Abstract: To understand the changes of endogenous hormones in tea plant [Camellia sinensis(L.) O. Kuntze] under natural low-temperature, ten-year-old tea plants of the cultivar ‘Longjingchangye’ were used as the material and the changes of endogenous hormones content were determined by enzyme-linked immunosorbent assay (ELISA). The results showed that the fluctuation amplitude of indole acetic acid (IAA) content is highest among all detected hormones during overwintering period. The change of abscisic acid (ABA) content was smaller than IAA but higher than that of gibberellins (GA3) and zeatinriboside (ZR). In addition, the changing trends of IAA, ZR and GA3 content is consistent, while the trend of ABA is different from them. Furthermore, the changes between ZR and GA3, ZR and IAA, IAA and GA3 content were significantly related. As well, there are significant positive correlations between ABA and IAA, ZR, respectively. All of the above results suggest that endogenous hormones in tea plant are closely related under natural low-temperature. Tea plant may regulate the ratio of ABA/(GA3 + IAA + ZR) to adapt to low temperature.

Key words: tea plant, natural low temperature, endogenous hormone
