Chickpea (Cicer arietinum L.) is a widely cropped pulse and an important source of proteins for humans. In Mediterranean regions it is predicted that drought will reduce soil moisture and become a major issue in agricultural practice. Nitrogen (N)-fixing bacteria and arbuscular mycorrhizal (AM) fungi have the potential to improve plant growth and drought tolerance. The aim of the study was to assess the effects of N-fixing bacteria and AM fungi on the growth, grain yield and protein content of chickpea under water deficit.
Plants inoculated with Mesorhizobium mediterraneum or Rhizophagus irregularis without water deficit and inoculated with M. mediterraneum under moderate water deficit had significant increases in biomass. Inoculation with microbial symbionts brought no benefits to chickpea under severe water deficit. However, under moderate water deficit grain crude protein was increased by 13%, 17% and 22% in plants inoculated with M. mediterraneum, R. irregularis and M. mediterraneum + R. irregularis, respectively.

鹰嘴豆（Cicer arietinum L.）是一种广泛种植的豆类，是人类重要的蛋白质来源。在地中海地区，预计干旱将减少土壤水分，成为农业生产中的一个主要问题。固氮细菌和丛枝菌根（AM）真菌有潜力促进植物生长并提高耐旱性。本研究的目的是评估固氮细菌和AM真菌对水分亏缺条件下鹰嘴豆生长、籽粒产量和蛋白质含量的影响。
在无水分亏缺条件下接种地中海中生根瘤菌或不规则根内球囊霉以及在中度水分亏缺条件下接种地中海中生根瘤菌的植株生物量显著增加。在严重水分亏缺条件下，接种微生物共生体对鹰嘴豆没有益处。然而，在中度水分亏缺条件下，接种地中海中生根瘤菌、不规则根内球囊霉以及地中海中生根瘤菌+不规则根内球囊霉的植株籽粒粗蛋白分别增加了13%、17%和22%。
