摘要

自 2000 年以来,新西兰的猕猴桃果园就出现了葡萄树衰退和树干病害。2019 年,人们注意到正在重新嫁接的 Actinidia chinensis var.从土壤上方 1-1.5 米处对 10 个有症状和 10 个外部无症状的树干进行横切,并在树干宽度范围内进行真菌分离。在有症状的藤本植物中发现的真菌包括 Neobulgaria alba、Ilyonectria spp.、Neonectria microconidia、Gliomastix murorum、Clonostachys sp.和 Penicillium sp.。不过,Neobulgaria alba 通常与木材中的染色区域非常吻合,而且没有从无症状的葡萄藤中发现。无症状葡萄树中最常见的真菌是 Chaetomium sp。需要进行致病性测试,以确认这些真菌中哪些是次生入侵者,哪些是该寄主的主要病原体。

Fungi found in association with discoloured wood of kiwifruit vines in New Zealand
Vine decline and trunk diseases have been observed in New Zealand kiwifruit orchards since the year 2000. In 2019, a block of Actinidia chinensis var. deliciosa ‘Hayward’ vines that were being re-grafted was noted to have differences in colouration of the internal wood of the cut trunks, with dark cores often corresponding with less vigorous vines and/or vines with trunk disorders. Cross-sections of 10 symptomatic and 10 externally asymptomatic trunks were taken from 1–1.5 m above the soil and fungal isolations made across the width of the trunks. Fungi found within the symptomatic vines included Neobulgaria alba, Ilyonectria spp., Neonectria microconidia, Gliomastix murorum, Clonostachys sp. and Penicillium sp. There was a wide variety of symptoms and fungal profiles seen. However, Neobulgaria alba often closely matched the stained areas seen in the wood and was not recovered from the asymptomatic vines. The most common fungus in the asymptomatic vines was Chaetomium sp. These isolations revealed a group of fungal genera that were associated with diseased trunks of kiwifruit at this site. Pathogenicity testing is needed to confirm which of these fungi are secondary invaders and which are primary pathogens of this host.
