The effects of gibberellin A(3) (GA(3)) on natural senescence and the relationship between gibberellins (GAs), abscisic acid (ABA), and senescence are not fully understood. For example, it is still unclear whether GA and ABA act antagonistically. There are only few reports on senescence-related changes in physiological parameters of herbaceous perennials.(More)
Senescence in perennials has not been extensively studied compared to that in annual plants, and the effects of delaying senescence on plant biomass and metabolic features in herbaceous perennials has also been poorly reported. We recently examined the effects of gibberellin A(3) (GA(3)) on senescence of aerial parts of Paris polyphylla, which characterize(More)
Diosgenin accumulation in cell suspension cultures of Dioscorea zingiberensis C. H. Wright was enhanced by treatment with saccharide elicitors from its endophytic fungus Fusarium oxysporum isolate Dzf17. The crude oligosaccharide was prepared by partial acid hydrolysis of the isolated Dzf17 fungal cell wall fragments. Optimal elicitation of diosgenin(More)
Many medicinal plants contain diosgenin, which has a significant medicinal value. However, there is currently no effective and rapid analytical method to determine the diosgenin content of plants or products. In the present work we have developed an indirect competitive enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of(More)
