Endogenous hormone levels in bearing and non-bearing shoots of walnut (Juglans regia L.) and their mutual relationships

The levels of endogenous gibberellic acid equivalents, indole acetic acid, trans-zeatin and trans-zeatin riboside in bearing and non-bearing shoots of walnut (Juglans regia L.) were detected by high-performance liquid chromatography during vegetation period.

Description
Summary:The levels of endogenous gibberellic acid equivalents, indole acetic acid, trans-zeatin and trans-zeatin riboside in bearing and non-bearing shoots of walnut (Juglans regia L.) were detected by high-performance liquid chromatography during vegetation period. The levels of endogenous hormones were analysed in four different shoot types of current season, bearing terminal shoot, non-bearing terminal shoot, bearing lateral shoot and non-bearing lateral shoot. Their average levels differed statistically at five sampling times from 25 May to 23 September. Relationships among changes in endogenous gibberellin, auxin and cytokinin contents were computed using correlation and regression analyses. Remarkable positive correlation coefficients were found among changes in gibberellin, auxin and cytokinin contents. Statistical findings indicated that changes in endogenous hormones exhibited a collective behaviour in walnut shoots during vegetation period.
