As endophytes, entomopathogenic fungi can protect plants against biotic and abiotic stresses and at the same time promote plant growth and plant health. To date, most studies have investigated whether can enhance plant growth and plant health, while only little is known about other entomopathogenic fungi. In this study, we evaluated whether root inoculation of the entomopathogenic fungi ARSEF 5128, ARSEF 3097 and ARSEF 3682 can promote plant growth of sweet pepper ( L.), and whether effects are cultivar-dependent. Plant height, stem diameter, number of leaves, canopy area, and plant weight were assessed four weeks following inoculation in two independent experiments using two cultivars of sweet pepper (cv. 'IDS RZ F1' and cv. 'Maduro'). Results showed that the three entomopathogenic fungi were able to enhance plant growth, particularly canopy area and plant weight. Further, results showed that effects significantly depended on cultivar and fungal strain, with the strongest fungal effects obtained for cv. 'IDS RZ F1', especially when inoculated with . We conclude that inoculation of sweet pepper roots with entomopathogenic fungi can stimulate plant growth, but effects depend on fungal strain and crop cultivar.
作为内生菌，昆虫病原真菌可以保护植物免受生物和非生物胁迫，同时促进植物生长和植物健康。迄今为止，大多数研究都调查了[具体真菌名称未给出]是否能促进植物生长和植物健康，而对于其他昆虫病原真菌却知之甚少。在本研究中，我们评估了对甜椒（[植物学名未完整给出]）根部接种昆虫病原真菌ARSEF 5128、ARSEF 3097和ARSEF 3682是否能促进其生长，以及这些影响是否依赖于品种。在两个独立实验中，使用两个甜椒品种（‘IDS RZ F1’和‘Maduro’），在接种四周后评估株高、茎直径、叶片数量、冠层面积和植株重量。结果表明，这三种昆虫病原真菌能够促进植物生长，尤其是冠层面积和植株重量。此外，结果表明这些影响显著依赖于品种和真菌菌株，对于‘IDS RZ F1’品种，尤其是接种[具体真菌名称未给出]时，真菌的影响最为强烈。我们得出结论，用昆虫病原真菌接种甜椒根部可以刺激植物生长，但效果取决于真菌菌株和作物品种。
