摘要
以石竹叶片为外植体， 诱导愈伤组织、营养芽、花芽的培养基分别为： ＭＳ＋ ＺＴ２．５ ｍｇ／Ｌ＋ ２，４Ｄ０．３ ｍｇ／Ｌ； ＭＳ＋ ＺＴ１ ｍｇ／Ｌ＋ ＢＡ２ ｍｇ／Ｌ＋ ＮＡＡ０ ．２ ｍｇ／Ｌ； ＭＳ＋ ＩＢＡ０ ．５ ｍｇ／Ｌ＋ ＮＡＡ０ ．３ ｍｇ／Ｌ。在石竹离体叶花芽形成过程中， 内源多胺含量呈不同的变化趋势， 腐胺、亚精胺含量上升， 而二丙胺、精胺含量下降， 表明多胺与石竹离体叶花芽分化有明显的内在联系。
Explants were taken from the leaves of Dianthus chinensis L.Callus vegetative shoots and flower buds were induced on the following media:MS+ZT 2.5mg/L+2,4 D 0.3mg/L;MS+ZT 1mg/L+BA 2mg/L+NAA 0.2mg/L;MS+IBA 0.5mg/L+NAA 0.3mg/L.In the course of forming flower buds,the contents of endogenous polyamines varied regularly,the contents of putrescine and spermidine rised,but the contents of spermine and diaminopropane decreased,this showes that there is obvious internal connection between polyamines and flower buds differentiation.
