摘要
１９８９年在中蒙边境樟子松林区大面积发生樟子松针枯病，该病危害严重，故笔者于１９９４年～１９９６年对该病原进行了分离培养。经鉴定引起该病害的病原菌为偃松壳针孢（ＳｅｐｔｏｒｉａｐｉｎｉｐｕｍｉｌａｅＳａｗａｄａ）和松穴褥盘孢（ＤｏｔｈｉｓｔｒｏｍａｐｉｎｉＨｕｌｂａｒｙ）。偃松壳针孢的分生孢子器球形，大小为１１９１～３２３４μｍ，高为１７６０～２４９９μｍ；分生孢子梗无色，大小为８８～２０５×２９～５７μｍ；分生孢子无色，大小为１７５～４６９×２９～５９μｍ，具２～４个分隔。松穴褥盘孢的分生孢子盘黑色，大小为１１１１～２２２２×１３３３～４８８８μｍ；分生孢子乳白色，线形，大小为１７３～３９５×２７～４２μｍ，具１～５个隔膜。
Wither fallen leaves on a large of area in Pinus sylvestris var mongolican stands along China-Mongolia border were found in 1989 The growth of the tree and the product of cones and seeds were affected greatly Through isolating of pathogen and artificial induced disease experiment from 1994 to 1996, it was found that the disease was needle blight caused by Septoria pinipumilae Sawada and Dothistroma pini Hulbaary The pycnidium of Septoria pini-pumilae Sawada is globular shape Its size is 119 1～323 4μm It is 176～249 9μm high The conidiophore has no colour, with the size of 8 8～20 52×2 9～5 7μm The conidium is colourless, with the of 7 5～46 9×2 9～5 9μm, separated into 3～5 parts The acervulus of the Dothistroma pini is black, with the size of 111 1～222 2×133 3～488 8μm The conidium is white, line shape, with the size of 17 3～39 5×2 7～4 2μm, separeted into 2～6 parts
