| 摘 要： | 选用三倍体毛白杨的幼苗作为培养材料, 选用MS培养基在组培室进行培养,从植物培养15 d开始每隔5d取样1次,进行培养基中K、Ca、Mg、Zn 、Fe、Mn元素的含量测定,以确定在这段时期内植物对上述6种元素的吸收程度.结果表明:Zn、Mn、Ca、Mg在培养物的生长过程中吸收比较均匀,K在早期吸收强烈,后期几乎不吸收.Fe在早期以及后期吸收量比较大,中期吸收量比较少.

| Abstract: | Cultured in MS medium in tissue culture room,triploid Chinese white poplar seedlings were used as training materials to study nutrient elements absorption during growth.The medium sample were taken every 5 days since the 15th day,whose K,Ca,Mg,Zn,Fe,Mn content were determined using atomic absorption spectrometer.Experimental results showed an even absorption of Zn,Mn,Ca,and Mg element,a strong K absorption in the early period and almost no K absorption in the late.The seedlings absorbed more Fe element in t... |
