Abstract

Wheat is one of the most important crops in the world. Its production can be influenced by a diversity of beneficial and pathogenic rhizospheric microbes, including fungi. Amongst them, beneficial spp. can be used as alternatives to chemical fertilizers, as they are cheap and harmless to the environment. Our study aimed to isolate, identify, and characterize spp. from Lebanon associated with wheat. Two strains belonging to , and species, were isolated and found to be endophytes, enhancing root growth and producing Indole-3-acetic acid. Inoculation also improved seedling development, and increased plant growth and yield. Furthermore, the two strains inhibit Fusarium growth . These spp. have thus the capacity to be used as organic fertilizers for wheat.

摘要

小麦是世界上最重要的作物之一。其产量会受到多种有益和致病的根际微生物(包括真菌)的影响。其中,有益菌种可作为化肥的替代品,因为它们价格低廉且对环境无害。我们的研究旨在从黎巴嫩与小麦相关的菌种中进行分离、鉴定和表征。分离出了两株分别属于[具体菌种1]、[具体菌种2]和[具体菌种3]的菌株,发现它们是内生菌,可促进根系生长并产生吲哚 - 3 - 乙酸。接种这些菌株还改善了幼苗发育,增加了植株生长和产量。此外,这两株菌株抑制了镰刀菌的生长。因此,这些菌种有能力用作小麦的有机肥料。
