摘要

在1985-1995年期间，在挪威四个轮作试验地点的单一栽培地块上，对胡萝卜中的针状芽孢杆菌感染进行了研究。在气候变化最大的两个地点，不同年份叶片和根部的针叶分枝杆菌感染发生率和严重程度变化最大。在这些地点，针叶虫对根系的侵害与7月降水呈显著正相关。在同一地点，叶片侵染率与根系侵染率显著相关。在一个地点，贮藏期的长短与贮藏中甘草腐病的发生率和严重程度相关。

Variations in Infection by Mycocentrospora acerina in Carrot Monoculture Plots at Four Sites during 1985-1995

Infection by Mycocentrospora acerina in carrots was examined in the period 1985-1995 in monoculture plots at four sites with crop-rotation experiments in Norway. At two of the locations, with the most variable climate, the incidence and severity of M. acerina infections on leaves and roots varied most through the different years. At these locations M. acerina attack on the roots was positively correlated with precipitation in July. At one location the incidence of leaf infection corresponded significantly with the incidence on the roots. At one site the length of the storage period correlated with the incidence and severity of liquorice rot in storage.
