Abstract

[Objective] To study the changes of endogenous hormones and fruit growth under drought stress treatments and the effect of two measures on alleviating drought. [Methods] 6-year-old Camellia oleifera forests were tested by applying natural condition, drought stress, covering straw and loosing soil. The endogenous hormones in leaves were studied by enzyme-linked immunosorbent assay (ELISA) and the fruit growth was also analyzed. [Results] (1) When the soil moisture content was lower than 24.0%-26.8%, the endogenous hormones began to appear larger changes. (2) The IAA content in leaves decreased, the ABA content increased, the GA content increased at first and then decreased, the ZR content decreased and then maintained at a low level, and the ZR/IAA values decreased under drought stress. Covering straw and loosing soil could effectively mitigate the effects of drought stress on the contents of IAA, GA and ZR. It had little effects on the ABA content and ZR/IAA values; C. oleifera forests dealt with drought stress by the changing the endogenous hormone content. (3) The fruit width growth decreased under drought stress and the fruit height growth was negative. With covering straw and loosing soil, the fruit width growth increased by 73.20% and 75.58% respectively and these two measures effectively alleviated the effects of drought stress on fruit height. [Conclusion] Production by the measures of covering straw and loosing soil can effectively alleviate the effects of drought stress on the fruit growth and covering straw as the best measure can be further applied.
