摘要
应用酶联免疫吸附测定法(ELISA)研究了石蒜与中国石蒜不同生长发育期鳞茎内源激素质量摩尔浓度的动态变化,分析了内源激素与2种石蒜生长发育的关系。结果表明,花芽分化前期2种石蒜鳞茎IAA浓度较低,而iPAs、ABA与GAs浓度较高;临近抽葶IAA浓度均有所增加,而iPAs与Zrs、ABA与GAs浓度均降到极值。花期ABA、GAs与ZR s浓度均有所回升,说明高浓度的ABA与GAs对2种石蒜的开花可能起正向调控的作用,但对叶生长的协同规律不明显。内源激素比例分析表明,ZR s/IAA、GAs/IAA、ABA/GAs三者比例高有利于2种石蒜的花原基分化,三者比例低则有助于2种石蒜的叶生长。
Variations of endogenous hormone contents in bulbs of both Lycoris radiata and Lycoris chinensis in different growth and development stages were studied with enzyme linked immunosorbent assay（ELSA）,the relationship between endogenous hormone and growth and developmen of two Lycoris plants were analyzed.The results showed the IAA content of two plants was low,but the contents of iPAs,ABA and GAs were high during the fruit bud differentiation stage.With the coming of florescence,the IAA content increased,while the contents of iPAs,ZRs,ABA and GAs fell to extremum.During florescence the contents of ABA,GAs and ZRs increased,this suggested the increasing of ABA and GAs contents played a stimulative role in the flowering of two plants,but the role in the growth of their leaves was not obvious.Relatively high ZRs/IAA,GAs/IAA and ABA/GAs ratios were beneficial for their floweral differentiation,while moderately decreasing of three ratios did the same for leaves growth.
