研究了丛枝菌根（AM）侵染对辣椒生长和产量的影响。11B 14）在高盐度下生长。实验在温室条件下在含有玉米和沙子（1：1，v/v）的混合物的盆中进行。治疗包括：（1）不添加NaCl而不添加丛枝菌根（NS-AM），（2）不添加NaCl而添加丛枝菌根（NS + AM），（3）添加50 mM NaCl而不添加丛枝菌根（S1-AM）和（4）添加100 mM NaCl而不添加丛枝菌根（S2-AM），（5）加入50 mM NaCl和丛枝菌根菌（S1 + AM），（4）加入100 mM NaCl和丛枝菌根菌（S2 + AM）。NaCl处理降低了辣椒地上部和根系的干物质含量，果实产量低于对照。N，P和K，在叶片中的浓度显着降低盐胁迫，然而，菌根定植的盐胁迫植物恢复叶片营养浓度的水平，在大多数情况下，在非胁迫植物。接种AM真菌可促进辣椒在盐和无盐条件下的生长，并减少细胞膜渗漏。(C)2009爱思唯尔有限公司版权所有。
This study investigated the effects of arbuscular mycorrhizal (AM) colonisation by Glomus clarum on growth and fruit yield of pepper (Capsicum annum cv. 11B 14)grown at high salinity. The experiment was conducted in pots containing a mixture of perlite and sand (1:1, v/v) under glasshouse conditions. Treatments were: (1) no added NaCl without arbuscular mycorrhizae (NS-AM), (2) no added NaCl with arbuscular mycorrhizae (NS + AM), (3) added 50 mM NaCl without arbuscular mycorrhizae (S1-AM) and (4) added 100 mM NaCl without arbuscular mycorrhizae (S2-AM), (5) added 50 mM NaCl with arbuscular mycorrhizae (S1 + AM) and (4) added 100 mM NaCl with arbuscular mycorrhizae (S2 + AM). The NaCl treatments reduced pepper shoot and root dry matter, and fruit yield compared with the non-saline treatments. The concentrations of N, P and K, in the leaves were significantly reduced by salinity stress, however, mycorrhizal colonisation of the salt-stressed plants restored leaf nutrient concentrations to the levels in non-stressed plants in most cases. AM inoculation improved pepper growth under salt or saltless conditions and reduced cell membrane leakage. (C) 2009 Elsevier B.V. All rights reserved.
