Evaluation of biological activity of new synthetic brassinolide analogs

Popis výsledku v původním jazyce

The responses of plants to exogenous treatment with new synthetic brassinosteroids (BRs) were assessed and compared with the activity of natural 24-epibrassinolide (24-EPI). Morphological experiments on plants of pea and flax showed that the boundary between stimulatory and inhibitory concentrations of individual BRs and 24-EPI used is very narrow and differs also with the plant species. Moreover brassinosteroids can exhibit effects similar to various other plant hormones. This was proven also in our experiments, where auxin, anti-auxin and cytokinin like effects were achieved by BRs application. One of the explanations of the different morphological effects could be the influence of brassinosteroid application on the level of endogenous hormones. There are changes in the levels of indole-3-acetic acid, 6 benzylaminopurine, trans-zeatin and dihydrozeatin in rape and wheat plants caused by BR 4 and 24-EPI application, but there is no general trend explaining unequivocally their influenc
