利用 79个辽宁松球壳孢菌菌株与 4个A型和B型标准菌株及 4个美国菌株进行菌落生长速度对比研究发现 ,除个别菌株外 ,辽宁菌株的菌落生长速度显著慢于供试的A型标准菌株和美国菌株 ;美国菌株与A型标准菌株的菌落生长速度相近 ,显著快于B型标准菌株 ;辽宁菌株之间也有显著差别。同时发现 ,光照可加快菌落离体生长速度
Colony growth of 79 strains of Pinus maydis in Liaoning and 4 strains of type A and B and 4 strains in the United States showed that except for individual strains, the colony growth rate of Liaoning strains was significantly slower than that of the tested ones A standard strains and the United States strains; the United States strains and A type of standard strains of colony growth rate is similar, significantly faster than the B type standard strains; Liaoning strains also have significant differences. Also found that light can speed up colony in vitro growth rate
