一、前言 1940年平塚直秀在小兴安岭森林中的东北茶藨子叶上,采到柱锈菌的冬孢子堆,定名为 Cronartium ribicola,并判断它的锈孢子可能产生在当地的红松与偃松上。1960年东北林学院潘学仁在小兴安岭带岭的东北茶藨子叶上采到柱锈菌的冬孢子堆,其后笔者多次在带岭、朗乡等地采到同类标本,都定名为 C.ribicola,并推测其锈孢子寄主为红松,然而都未经人工接种试验证明。 1976—1978年,笔者用红松上的锈孢子向马先蒿及茶藨子接种,虽然得到阳性结果,但因在茶藨子叶上只产生了夏孢子堆而未产生冬孢子堆即被旱死,所以菌种仍未确定。为了证实红松上的锈孢子,对马先蒿和茶藨子的寄生关系,1979年在黑龙江省鸡东县宝泉林场,进行了多次人工接种试验,结果如下。
I. INTRODUCTION In 1940 Hiratsuka Straight appeared in the forest of Mt. Xiaoxing’anling to collect the teliospores of C. tyrannu, named Cronartium ribicola, and judged its rust spores may be produced on native Korean pine and Japanese pine . In 1960, Pan Xueren, Northeast Forestry College, collected the teliospores of Pseudoperonospora crassifolia on the leaves of the northeast tea plantation in Xiaoxing’anling Ridge. Later on, the author collected many specimens of the same kind in the belts and Lang townships, all named C.ribicola , And speculated that the rust spore host was Korean pine, but none of the artificial inoculation test proved. From 1976 to 1978, the author inoculated with Artemisia annua and Chardonnay seedlings with the rust spores on Korean pine, although positive results were obtained. However, only the summer spores were produced on the leaves of Chaxingu and the winter sporophytes were not produced, So the strain has not been determined. In order to confirm the pine spores on the pine, the parasitic relationship between Artemisia scoparia and tea gizzard, 1979 in Heilongjiang Jidong Baoquan Forest Farm, conducted a number of artificial inoculation test, the results are as follows.
