| 摘 要： | 人工接种试验结果表明,雪腐格氏霉(Gerlachia nivalis)引起的小麦成株期叶枯、鞘枯和穗腐,鞘枯使小麦穗粒重减少2.1％～27.1％,千粒重降低9.5％～16.9％;穗腐使小麦穗粒重减少9.6～33.9％,千粒重降低7.8％～17.9％;鞘枯—穗腐复合症状使穗粒重减少10.2％～55.2％,千粒重下降9.5％～14.8％;叶斑—鞘枯—穗腐使穗粒重减少11.7％～47.1％,千粒重下降12.1％～18.3％。

| Abstract: | The results by artificial inculation testing showed that infection of Ger-lachia nivalis Caused leaf spot, sheath death and ear blight, Which reduced Rernel wight per spike and thousand kernel wight, sheat death reduced 2.1%-27. 1% and 9. 5%-16. 9%;Ear blight reduced 9. 6%-33. 9% and 7. 8%-17. 9%;Sheal death-ear blight complex symptom reduced 10. 2%-55. 2% and 9. 5%-14. 8%;Leafspot-sheat death-ear blight complex symptom reduced11. 7%-47. 1% and 12.1%-18.3%. |
