Abstract: The leaf digestibility and mineral content of 10 grasses of Triticeae were analyzed by using scanning microscope and energy dispersive X ray technique.The order of leaf digestibility of the grasses was Elymus sibiricus>Hordeum brevisubulatum>Agropyron cristatum cv.‘Fairway'= E.Canadensis>A.cristatum×A.desertorum cv.‘Hycrest Mongnon'> A.desertorum cv.'Nordan'> E.excelsus≥Psathyrostachys juncea=E.dahuricus>A.mongolicum. The mineral element content range in the leaves of the tested grasses was Mg 0.21%～0.57%,Si 0.90%～3.31%,P 0.27%～0.36%,S 0.36%～0.60%,Cl 0.21%～ 0.52%, K 1.44%～3.06%,Ca 0.42%～0.98%,and the differences among the grasses were significant.

摘要： 利用扫描电镜及能量分散型荧光X射线新技术分析小麦族10种多年生禾草叶片的可消化性和矿物质含量.结果表明,供试草种叶片可消化性的高低顺次是:老芒麦>野大麦>航道冰草=加拿大披碱草>蒙农杂种冰草>诺丹冰草>肥披碱草≥新麦草=披碱草>蒙古冰草.叶片中7种矿物元素含量变幅为:Mg 0.21%～0.57%、Si 0.90%～3.31%、P 0.27%～0.3%、S 0.3%～0.0%、Cl 0.21%～0.52%、K1.44%～3.0%、Ca 0.42%～0.98%,草种间差异显著.
