摘要
用植物激素的酶联免疫吸附测定法(ELISA)测定不同时期东北铁线莲种子内源激素IAA、ABA、GA、ZR的动态变化。结果表明:低温层积初期东北铁线莲种子ABA的含量呈较明显的下降趋势;进入生理后熟期以后,GA、ZR的含量持续升高,抑制萌发物质减少及促萌物质的增加与积累,最终导致东北铁线莲种胚休眠的解除。
To investigate dynamic changes of endogenesis hormone IAA,ABA,GA,ZR in its post-ripening by ELISA in the seed embryo post-ripening.At early stage of low temperature lamination,the ABA content of the seeds was on a declining curve and quite evident.The GA,ZR content persistently increased after physiology after-ripening.The reduction of inhibitory substances,and increment and accumu-lation of promoting germination substances led to dormancy-release of seed embryo.
