In this study, the physio pathological effects of Aspergillus alliaceus (Aa, fungi, biocontrol agent) on Orobanche (parasitic plant) were investigated by hormone and phenolic substance tests. In experimental group, Orobanches were treated with the fungi, considering control group was fungus-free. Based on the hormonal tests, in the experimental group, salicylic acid (SA), jasmonic acid (JA), abscisic acid (ABA) and gibberellic acid (GA) levels significantly decreased, and only indole acetic acid (IAA) hormone levels were fairly higher than the control group. According to phenolic substance tests, it was found that only gallic acid, syringic acid and caffeic acid values significantly increased compared with control, and catechin and p-coumaric acid values were significantly lower. Consequently, it was determined that Aa pathogenesis (1) considerably reduces the effects of all defence hormones (JA, ABA, SA), (2) operates an inadequate defence based solely on the IAA hormone and several phenolic substances (gallic acid, syringic acid and caffeic acid), (3) and inevitably the fungi lead the Orobanche to a slow and continuous death. The results were evaluated in detail in the light of similar recent article and current literature in terms of biocontrol and pathology.

Aspergillus alliaceus 感染致命地改变 Orobanche 激素和酚类代谢

在这项研究中，通过激素和酚类物质测试研究了葱曲霉（Aa，真菌，生物防治剂）对 Orobanche（寄生植物）的生理病理影响。在实验组中，Orobanches 用真菌处理，考虑到对照组没有真菌。激素检测结果显示，实验组水杨酸（SA）、茉莉酸（JA）、脱落酸（ABA）和赤霉酸（GA）水平显着下降，只有吲哚乙酸（IAA）激素水平相当高于对照组。根据酚类物质测试发现，与对照相比，只有没食子酸、丁香酸和咖啡酸值显着升高，而儿茶素和对香豆酸值显着降低。最后，已确定 Aa 发病机制 (1) 显着降低所有防御激素 (JA、ABA、SA) 的作用，(2) 仅基于 IAA 激素和几种酚类物质（没食子酸、丁香酸和咖啡酸）的防御能力不足酸)、(3) 以及不可避免的真菌导致 Orobanche 缓慢而持续的死亡。根据生物防治和病理学方面的近期类似文章和当前文献，对结果进行了详细评估。
