Influence of intercropping and mycorrhization on two modern Triticum turgidum subsp. durum cultivars and their microbiota

An intercropping system is based on the interplay between cereals and legumes, and represents a promising way to promote sustainable agriculture. It is influenced by the interaction between roots and the soil microbial communities, including also arbuscular mycorrhizal fungi (AMF). In this context a fundamental question might be if different plant genotypes can differently interact with microorganisms. To address this issue, a 2-year field study was carried out, verifying the effects of intercropping and mycorrhizal inoculation on two varieties of durum wheat and a variety of lentil in different combinations on agronomic and grain features, as well on microbial communities of soil, rhizosphere and roots.

间作系统以谷类作物与豆科植物的互作为基础，是推动可持续农业发展的极具潜力的路径。该系统受根系与土壤微生物群落（包括丛枝菌根真菌（arbuscular mycorrhizal fungi，AMF））之间的互作影响。在此研究背景下，一个核心问题是：不同植物基因型能否与微生物产生差异化的互作关系。为解答这一问题，本研究开展了为期2年的田间试验，验证不同组合模式下的间作与菌根接种对2个硬粒小麦品种、1个小扁豆品种的农艺性状与籽粒特征的影响，同时分析其对土壤、根际及根系微生物群落的作用。
