Comparison of endogenous cytokinins and cytokinin oxidase/dehydrogenase activity in germinating and thermoinhibited Tagetes minuta achenes

Popis výsledku v původním jazyce

Tagetes minuta L achenes are thermoinhibited at temperatures above 35 degrees C and have accelerated radicle emergence (germination) when subsequently transferred to an optimal temperature (25 degrees C). Endogenous cytokinins and cytokinin oxidase/dehydrogenase (CKX) activity were compared in normally germinating (25 degrees C) and thermoinhibited (72 h at 36 degrees C then transferred to 25 degrees C) T. minuta achenes. Following imbibition, endogenous cytokinin concentrations changed in normally germinating T. minuta achenes, with a gradual decrease in dihydrozeatin-type (DHZ) cytokinins, a large increase in cis-zeatin-type (cZ) cytokinins, a smaller increase in N-6-(2-isopentenyl)adenine-type (iP) cytokinins and a peak of transzeatin-type (tZ) cytokinins at 13 h. These changes in the isoprenoid cytokinin profile were similar in the thermoinhibited achenes imbibed at 36 degrees C, despite the thermal block preventing radicle emergence. The exception was the iP-type cytokinins that o
