説明
Abstract Biological activities of brassinolide, its biosynthetic intermediates and some biosynthetically related brassinosteroids were evaluated using modified dwarf rice lamina inclination bioassay. A very strong synergistic effect was observed when IAA was applied together with brassinosteroid. In particular co-application of brassinosteroid and 5 μg IAA was ca. 300 times more active than a single application of brassinosteroid. Under co-application of 5 μg IAA, the minimum detectable amount of brassinolide was less than 0.01 ng/rice plant. Biological activity increased according to the order of the biosynthetic pathway. Brassinosteroids in the early C-6 oxidation pathway (6-oxobrassinosteroids) were more active than corresponding brassinosteroids in the late C-6 oxidation pathway (6-deoxobrassinosteroids). Even very early biosynthetic intermediates such as campestanol showed some activity in our modified bioassay.
