The genus has significant economic importance since it is cultivated and consumed worldwide for its flavor and pungent properties. In 2021, Mexico produced 3.3 billion tons on 45,000 hectares which yielded USD 2 billion in exports to the USA, Canada, Japan, etc. Soil type has a dramatic effect on phosphorus (P) availability for plantsdue to its ion retention.In a previous study, novel fungal isolates were shown to solubilize and mineralize P in different kinds of soils with different P retention capacities. The aim of this work was to study the effects of the mineralogy of different kinds of "milpa" soils on the germination, biomass production, and P absorption of chili plants (). The germination percentage, the germination speed index, and the mean germination time were significantly increased in the plants treated with dual inoculation. Foliar phosphorus, growth variables, and plant biomass of chili plants grown in a greenhouse were enhanced in different soil types and with different inocula. Correlation studies suggested that the most significant performance in the foliar P concentration and in the growth response of plants was achieved in Vertisol with dual inoculation of 7 × 10 mL spores per chili plant, suggesting this would be an appropriate approach to enhance chili cultivation depending on the soil type. This study stresses the importance of careful analysis of the effect of the soil type in the plant-microbe interactions.
该属具有重要的经济意义，因为它因其风味和辛辣特性在全球范围内被种植和食用。2021年，墨西哥在4.5万公顷的土地上生产了33亿吨，向美国、加拿大、日本等国家出口，创收20亿美元。由于土壤对离子的保留作用，土壤类型对植物有效磷（P）含量有显著影响。在之前的一项研究中，新型真菌分离物被证明能在不同磷保留能力的各类土壤中溶解和矿化磷。这项工作的目的是研究不同类型“米尔帕”土壤的矿物学对辣椒植株（）发芽、生物量生产和磷吸收的影响。双重接种处理的植株的发芽率、发芽速度指数和平均发芽时间显著提高。在不同土壤类型和使用不同接种物的情况下，温室种植的辣椒植株的叶片磷含量、生长变量和植物生物量均有所增加。相关性研究表明，在每株辣椒接种7×10 mL孢子双重接种的变性土中，植株叶片磷浓度和生长反应表现最为显著，这表明根据土壤类型，这将是一种提高辣椒种植产量的合适方法。本研究强调了仔细分析土壤类型在植物-微生物相互作用中的影响的重要性。
