摘要

木兰“蝴蝶”是由M.acuminata和M.denudata杂交而成的落叶杂交品种。它是一种金字塔形的观赏树或多茎灌木，在美国农业部的耐寒区5至9生长良好，开着芳香的淡黄色花朵。2021年7月6日，在弗吉尼亚州费尔法克斯县的一个观赏植物苗圃进行的一项调查中，在18.9升的花盆中，11株植物中有6株下部枝条出现叶片坏死和早衰。

First Report of Phytophthora nicotianae causing leaf necrosis on Magnolia ‘Butterflies’ in a Virginia ornamental plant nursery

Magnolia ‘Butterflies’ is a deciduous hybrid cultivar resulting from a cross between M. acuminata and M. denudata. It is a pyramidal ornamental tree or multi-stemmed shrub that grows well in USDA hardiness zones 5 to 9, with fragrant, canary yellow flowers. On 06 July 2021, during a survey at a Fairfax County, VA ornamental plant nursery, six out of 11 plants in 18.9-liter pots exhibited leaf necrosis and premature senescence on the lower branches.
