Eggplant cultivation is subjected to attacks by numbers of pests and diseases from the nursery stage until harvest. Root-knot nematode () is one of the most significant restrictions in the successful cultivation of eggplant as it damages the crop year-round. One of the most essential classes of plant symbionts is arbuscular mycorrhizal fungi (AMF) and phosphate solubilizing bacteria (PSB), which significantly impact plant development, feeding, disease tolerance, and resistance to . Eggplant seedlings were inoculated with two mycorrhizal fungi, Glomus mosseae (Gm) and Gigaspora gigantea (Gg), together with the phosphate-solubilizing bacteria (PSB) (Pf; ATCC-17400) under the presence of nematodes inoculation of s 1000 eggs of in each pot. Observations were recorded for 9 morphological traits, 6 fruit morphometric traits using Tomato Analyzer (version 4) software program, and 4 fruit biochemical traits. Along with the data recorded for mycorrhization (%), number of galls and reaction to RKN. Plants inoculated with the consortium (Pf + Gm + Gg) performed substantially better for most traits. Furthermore, the eggplant plants treated with consortium developed the highest levels of fruit biochemical content along with the highest level of mycorrhization (68.20%). Except for certain fruit morphometric traits, the treatment containing Pf + Gg outperformed the treatment containing Pf + Gm. Overall, this research showed that AM fungi could be a sustainable solution to the eggplant RKN problem.
从育苗期到收获期，茄子种植都会受到多种病虫害的侵袭。根结线虫是茄子成功种植的最主要限制因素之一，因为它全年都会危害作物。丛枝菌根真菌（AMF）和溶磷细菌（PSB）是最重要的植物共生体类别之一，它们对植物的生长发育、养分吸收、抗病能力以及对根结线虫的抗性都有显著影响。在每盆接种1000个南方根结线虫卵的线虫接种条件下，将两种菌根真菌，即摩西球囊霉（Gm）和巨型球囊霉（Gg），与溶磷细菌（PSB）（解磷假单胞菌；ATCC - 17400）一起接种到茄子幼苗上。记录了9个形态学性状、使用番茄分析仪（版本4）软件程序测量的6个果实形态特征以及4个果实生化特征。同时记录了菌根侵染率（%）、根瘤数量和对根结线虫的反应数据。接种组合（Pf + Gm + Gg）的植株在大多数性状上表现明显更好。此外，用该组合处理的茄子植株果实生化含量最高，菌根侵染水平也最高（68.20%）。除了某些果实形态特征外，含有Pf + Gg的处理优于含有Pf + Gm的处理。总体而言，这项研究表明，AM真菌可能是解决茄子根结线虫问题的可持续方案。
