摘要
以山鸢尾、溪荪幼苗为试材,采用Hoagland完全营养液为对照,对幼苗进行缺素(N、P、K、Ca、Mg)营养液培养处理,研究了缺素处理对其叶绿素和蛋白质含量的影响。结果表明:缺N、K、Mg元素处理,可使山鸢尾及溪荪体内叶绿素含量下降,影响作用大小为N>K>Mg,山鸢尾>溪荪;缺P、Ca元素处理可使蛋白质含量大幅度下降,影响作用大小为P>Ca。
Taking two kinds of Iris as materials,using Hoagland nutrient fluid as control,influence of nutritional deficiency（N、P、K、Ca、Mg）on contents of chlorophyll and protein of Iris setosa and Iris sanguinea was investigated.The results showed that chlorophyll content of Iris setosaand Iris sanguineadecreased without N、K and Mg element,the order was N〉K〉Mg,Iris setosaIris sanguinea.Protein content decreased without P and Ca element,the order was P〉Ca.
