摘要: The biomass structure and the contents of (ABA) cytokinins (zeatin plus zeatin riboside) were studied in flowering plants ten herbaceous species Middle Urals representing stress-tolerant (S) ruderal (R) ecological strategies. plants, which explicitly manifested S- R-strategies, differed ABA cytokinin concentrations phytohormone partitioning particular organs. Higher accumulation leaves especially reproductive organs (here concentration exceeded by several times that cytokinins) was characteristic R-plants as compared to S-plants. In addition, higher roots, whereas, S-plants, dominated (in latter, content ABA). diverse hormonal status R- S-species is discussed relation patterns plant growth development photosynthate transport two authors conclude ability maintain typical balance instrumental acquiring specific
