摘要

本研究旨在评价仙人掌根际真菌对植物生长的促进作用。分离物具有溶解磷酸盐、产生乙酸-3-吲哚（AIA）、对抗植物病原体和在水下生长的活性。对所有测试结果进行统计分析。所研究的分离株能够溶解磷酸盐，其中F04（曲霉属）和F05（辐射状小蠊属）是表现出最高溶解指数的分离株。至于AIA的产生，F02（青霉属）和F07（曲霉属）是最有希望的。所有菌株都能抑制炭疽菌和镰刀菌的生长。水分限制为所有菌株提供了菌丝生长。因此，这些特性赋予了植物作为生长促进剂的特性。

In vitro bioprospecting of rhizospheric fungi associated to cactus (Opuntia cochenillifera) to plant growth promotion

This study aimed to evaluate in vitro the plant growth promotion capacity of rhizospheric fungi from Opuntia cochenillifera. The isolates were submitted to phosphate solubilization, acetic acid-3-indole (AIA) production, antagonism against phytopathogens, and growth under water activity. All test results were subjected to statistical analysis. The studied isolates were able to solubilize phosphate, being F04 (Aspergillus sp.) and F05 (Coprinellus radians) the ones that presented the highest solubilization indices. As to produce AIA, F02 (Penicillium sp.) and F07 (Aspergillus sp.) were the most promising. All isolates could inhibit the growth of Colletotrichum sp. and Fusarium sp. Water restriction provided mycelial growth for all isolates. Therefore, these characteristics confer characteristics as growth promoters in plants.
