| 摘 要： | 红皮云杉叶锈病发生在小兴安岭林区,该林区的地理位置是48°～48°43′N,12°23′～130°19′E,总面积 51.8万 ha(包括东风、新青林业局)。此病害过去仅危害过伐林下层的幼龄林木,不引起人们的重视。但近年来已扩展到5～10年生的人工林木及林间苗圃的苗木上,严重地影响云杉人工林的生长量和苗木产量,给林业生产造成较大的损失(图版Ⅰ-1)。为此从1984～1986年开展了本项试验,现将有关病原菌接种试验和生活史部分的研究结果报道如下。

| Abstract: | Leaf rust of Picea koraiensis L. is caused by Chrysomyxa rhodod-endri de Bary. Its pycnia, aecia occur on the first-year new leaves. They reduce forest increment by causing premature defoliation. Its uredinia occur on the leaves of Rhododendron dahuricum. They are orange-coloured and exc-urrent. But a few uredinia occur on the shoots. Telia are brownish-red colour and oval in shape. It will produce basidiospores in the following summer and reinfect the shoots of Picea koraiensis. |
