Changes in endogenous abscisic acid and cold hardiness in Actinidia treated with triazole growth retardants
1993
Tafazoli, E. | Beyl, C.
Soil drench of either paclobutrazol or uniconazole (0.4 mg/pot) was applied to plants of Actinidia arguta, "Ananasnaja," to determine the effect on endogenous abscisic acid measured in November, January, and March, and the concomitant cold hardiness of the treated plants. Both paclobutrazol and uniconazole treatments significantly increased cold hardiness. Paclobutrazol was more effective in increasing ABA levels compared to uniconazole. Abscisic acid was found to be highest in January, corresponding to deep dormancy, and least in March when plants were undergoing vegetative bud break. Paclobutrazol delayed vegetative bud break by 6.3 days, while uniconazole delayed bud break by 2.9 days.
