菌根技术是一种很有前途的园艺生物技术，可以使受各种非生物胁迫的植物受益。以枇杷（Eriobotrya japonica Lindl.）为试材，研究了3种丛枝菌根真菌（Acaulospora laevis、Glomus mosseae和Glomus caledonium）对枇杷生长和养分吸收的影响。研究了三种水分状况（充分浇水、轻度水分胁迫、重度水分胁迫）下的幼苗。结果表明，接种菌的幼苗干生物量、株高和总叶面积均高于未接种菌的幼苗。AMF对重度水分胁迫幼苗的影响最大，其次是轻度水分胁迫幼苗和充分供水幼苗。结果表明，所有AM真菌均能增加对氮、钾、磷、钙、镁、锌、铜的吸收，且菌根对养分吸收的贡献与其对生物量的贡献呈正相关。结果表明，接种丛枝菌根真菌提高了枇杷幼苗对干旱胁迫的耐受性，而丛枝菌根真菌提高了枇杷幼苗对营养元素的吸收能力，这是枇杷幼苗对干旱胁迫耐受性的重要原因。
Mycorrhizal technique is a promising biotechnology in horticultural industry, benefiting plants exposed to diverse abiotic stresses. In this study, the effects of three arbuscular mycorrhizal fungi (AMF), Acaulospora laevis, Glomus mosseae, and Glomus caledonium on plant growth and nutrient uptake of loquat (Eriobotrya japonica Lindl.) seedlings under three water regimes (well watered, water stressed-slight, water stressed-heavy) were investigated. Results showed that inoculated seedlings had higher dry biomass, plant height, and total leaf areas than those un-inoculated ones. AMF effect was the greatest for water stressed-heavy seedlings, followed by water stressed-slight seedlings and well watered seedlings. All AMF species increased the uptake of nitrogen (N) potassium (K), phosphorus (P), calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), and the mycorrhizal contributions to the nutrient uptake were positively related to that to the biomass. Data suggest that AMF inoculation increases the tolerance of loquat seedlings to drought stress, and the improved nutrient uptake by AMF contributes greatly to the tolerance.
