Abstract

We investigated the effect of different dosages of gibberellin biosynthesis inhibitory acylcyclohexanediones, prohexadione-calcium (PCa) and trinexapac-ethyl (TNE), on growth and flowering of Matthiola incana (L.) R. Br. PCa promoted stem elongation at all dosages treated, and PCa treated plants continued to grow even 12 weeks after treatment started. Treatments of 20 μg and 200 μg of PCa showed a similar promotive effect, but the promotive effect of 2 μg of PCa abated 8 weeks after treatment started. Treatments of 1 ug and 10 μg of TNE promoted stem elongation. Plants treated with 1 μg of TNE showed a continuous stem elongation for 12 weeks after treatment started. Plants treated with 10 μg of TNE reached to plateau at 10 weeks after treatment started. Treatment of 100 μg of TNE inhibited stem elongation in the early stage of growth, while promoted in the late stage of growth, and these plants also showed a continuous stem elongation for 12 weeks after treatment started. On the other hand, plants treated with the lowest dose of PCa (2 μg) were in floral stage 0 and the lowest dose of TNE (1 μg) caused one of 12 plants to flowering. All other treatments promoted flowering. Promotion of stem elongation and flowering by the acylcyclohexadiones seemed to be caused from an inhibition of 2β-hydroxylation of endogenous GA₄ and a consequent accumulation of endogenous GA₄.
