Growth of guayule (Parthenium argentatum A. Gray) in a moderate and a highly saline-sodie soil was increased by inoculation with Glomus intraradices Schenck & Smith. The growth of guayule plants was stimulated equally by the addition to the soil of either 100 μg g of phosphorus (P) or inoculum of G. intraradices. Mycorrhizal plants had increased concentrations of PO and decreased concentrations of Na in shoot tissues compared to non inoculated control plants. Addition of 100/μgg of P to the soil increased the accumulation of PO in the shoot tissues and in most instances decrease accumulation of Cu, Zn, Na, K, and SO . Concentrations of Na, K, and Cl and frequently Mn in the shoot tissues were increased while the concentrations of PO and SO in shoot tissues were generally decreased by the addition of NaCl to the soil. Addition of 100μgg of P to the soil did not markedly affect the colonization of guayule roots by G. intraradices. The roots of mycorrhizal guayule grown in soil with NaCl added contained decreased numbers of arbuscules and vesicles. Addition of both P and NaCl to the soil reduced the formation of arbuscules and vesicles and reduced the occurrence of moderate and heavy levels of root colonization.
接种摩西球囊霉（Glomus intraradices Schenck & Smith）可促进银胶菊（Parthenium argentatum A. Gray）在中度和高盐碱化土壤中的生长。向土壤中添加100μg/g的磷（P）或接种摩西球囊霉对银胶菊植株生长的促进作用相同。与未接种的对照植株相比，菌根植株地上部组织中磷的浓度增加，钠的浓度降低。向土壤中添加100μg/g的磷可增加地上部组织中磷的积累，且在大多数情况下会减少铜、锌、钠、钾和硫酸根的积累。向土壤中添加氯化钠会增加地上部组织中钠、钾、氯以及锰（通常情况下）的浓度，同时地上部组织中磷和硫酸根的浓度通常会降低。向土壤中添加100μg/g的磷对摩西球囊霉在银胶菊根上的定殖没有显著影响。在添加了氯化钠的土壤中生长的菌根银胶菊的根中，丛枝和泡囊数量减少。向土壤中同时添加磷和氯化钠会减少丛枝和泡囊的形成，并减少中度和重度根系定殖的发生。
