A new growth medium which closely approximates the composition of the soil solution is presented. This soil solution equivalent (SSE) medium contains the following components (millimolar): NO(3), 2.5; NH(4), 2.5; HPO(4), 0.005; Na, 2.5; Ca, 4.0; Mg, 2.0; K, 0.503; Cl, 4.0; SO(4), 5.0; ethylenediamine-di(o-hydroxyphenylacetic acid), 0.02; and MES [2-(N-morpholino)ethanesulfonic acid] (to maintain the pH at 6.0), 10, plus 0.1% arabinose. The advantages of the SSE medium are discussed.
现提出一种新的生长培养基,其成分非常接近土壤溶液的组成。这种土壤溶液当量(SSE)培养基含有以下成分(毫摩尔):NO3,2.5;NH4,2.5;HPO4,0.005;Na,2.5;Ca,4.0;Mg,2.0;K,0.503;Cl,4.0;SO4,5.0;乙二胺二(邻羟苯基乙酸),0.02;MES[2-(N-吗啉基)乙磺酸](维持 pH 值在 6.0),10,外加 0.1%阿拉伯糖。讨论了 SSE 培养基的优点。
