摘要
对来自不同发病程度，不同地点的国外松枯梢病松色二孢菌的９个菌株的生长、产孢等生物学特性进行了研究。结果表明，各菌株生长的最适温度为２５～３０℃，ｐＨ值为６～７，相对湿度为９０％以上；９２４５、Ｈ２１二菌株对湿度、ｐＨ值和培养基的适应范围都较广，且产孢量多；在培养基中加入１‰的硼对各菌株的生长和产孢有不同程度的抑制作用，尤以抑制产孢最明显，表现出硼对国外松枯梢病的发生。
Samples of nine strains of Diplodia pinea were collected from slash and loblolly pine plantations at various locations. A study on biological characteristic of strains was conducted and the result showed that all the strains grew well at 25～30℃ and over 90% of relative humidity under pH 6～7 in cultural media. Both strains 9245 and H 21 also could grow well at various conditions. The growth responses to boron were significant especially for spore growing. Boron may be used for Diplodia pinea control in exotic pine plantations.
