Almond anthracnose, primarily caused by , severely affects intensively irrigated almond orchards. This polyphagous pathogen is dispersed among plants by rain splashes. Consequently, weeds may contribute to the survival and dispersal of the inoculum during the almond tree's dormant period. This study investigated how interacts with plants from various species in the spontaneous flora of almond orchards and how these plant species may influence the maintenance and spread of inoculum and the disease. After inoculating a collection of plants with conidia, it was observed that the fungus can cause symptoms and signs on and on and act as an epiphyte with the ability to maintain and multiply conidia on , , , , , and , thus contributing to the survival and multiplication of the inoculum. Conidia germinated and produced appressoria on , , , , , and but no further development was detected, suggesting that these plants may limit the spread of the pathogen. A better understanding of the susceptibility of almond orchard flora will support optimized vegetation management to reduce inoculum reservoirs.
杏仁炭疽病主要由[病原体名称缺失]引起，严重影响集约灌溉的杏仁园。这种多食性病原菌通过雨水飞溅在植物间传播。因此，杂草可能在杏仁树休眠期对接种体的存活和传播起到作用。本研究调查了[病原体名称缺失]如何与杏仁园自发植物群落中的各种植物相互作用，以及这些植物物种如何影响接种体和病害的维持与传播。在用[病原体名称缺失]分生孢子接种一组植物后，观察到该真菌可在[植物名称1]、[植物名称2]上引起症状和病征，并作为附生菌在[植物名称3]、[植物名称4]、[植物名称5]、[植物名称6]、[植物名称7]和[植物名称8]上维持和繁殖分生孢子，从而有助于接种体的存活和繁殖。分生孢子在[植物名称9]、[植物名称10]、[植物名称11]、[植物名称12]、[植物名称13]、[植物名称14]和[植物名称15]上萌发并产生附着胞，但未检测到进一步发育，表明这些植物可能限制病原体的传播。更好地了解杏仁园植物群落的易感性将有助于优化植被管理，以减少接种体库。
