Abstract
AS98,a novel super-dwarf mutant of cotton(gossypium hirsutium L.),was used to study the dwarf-mechanism.AS98 treated by different exogenous hormones of GA3,BR and IAA at budding stage,and the changes of endogenous hormones GA,IAA,ZR and ABA,and activities of α-amylase,POD and SOD in leaves were investigated.The contents of endogenous GA,IAA,ZR and ABA measured by ELISA method.The activities of α-amylase,POD and SOD were investigated by 3,5-dinitrosalicylic acid method,guaiacol method and nitroblue tetrazolium(NBT) method,respectively.The results indicated that the contents of endogenous GA,IAA,ZR and ABA were increased in the leaves of AS98 after treated with exogenous GA3(0.15μmol /L).The variance rates(VR) of GA,IAA,ZR and ABA were 60.4% ～ 64.5% ,6.8% ～ 12.3% ,11.7% ～ 30.7% and 45.7% ～ 82.3% ,respectively.The biosynthesis of GA and IAA were promoted 49% and 0.67% by the lower concentration of exogenous IAA.After spraying exogenous IAA,the content of endogenous ABA was increased by 5.1% ～ 35.4% ,but the content of ZR was decreased 21.5% ～ 30.2% .Exogenous BR promoted endogenous GA and ABA synthesis,and reduced endogenous ZR content,but the influence on the content of endogenous IAA had obvious concentration effect.The VRs of GA,ABA and ZR were 25.3% ～ 30.4%,3.0% ～ 65.6% and-32.1% ～-40.9% ,respectively.The content of endogenous IAA was increased by application of lower concentration exogenous BR and decreased by application high concentration BR.The α-amylase activity was up-regulated 82% by the lower concentration exogenous GA3(0.15μmol /L).On the contrary,the α-amylase activity was reduced 42% by application exogenous PP333(1.2μmol /L),and the effect could be rescued by application exogenous GA3.The SOD activity were increased 35% by application PP333(0.15μmol /L),but it was inhibited 48% by application GA3(0.15μmol /L).Those results showed that AS98 was a GA deficient dwarf mutant.The application of the exogenous GA3 could significantly increase endogenous hormones both promoting and inhibiting plant growth,upregulate the α-amylase activity and decrease the POD and SOD activities.Moreover,the inhibition effect of α-amylase activity by application exogenous PP333 could be relieved by application exogenous GA3.
