摘要
人工接种试验结果表明，雪腐格氏霉引起小麦成株期叶枯、鞘枯和穗腐。鞘枯使小麦穗粒重减少０．８％～３２．９％，千粒重降低９．５％～１６．９％；穗腐使小麦穗粒重减少９．６％～３９．８％，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％～６５．２％，千粒重下降９．５％～１４．８％，叶斑－鞘枯－穗腐使粒重减少１１．７％～５１．５％，千粒重下降１２．１％～１８．３％。
The results of artifical inoculation test showed that wheat leaf spot,sheath wilt and ear blight were infected by Gerlachia nivalis fungi in adult wheat stage,The kernel weight per spike and thousand kernel weight of wheat by the sheath death were reduced at 0.8% 32.9%and 9.5% 16.9%respec tively,and at 9.6% 39.8%and 7.8% 17.9%by ear blight,respectively. The kernel weight per spike and thousand kernel weight of wheat were reduced at 10.2% 55.2%and 9.5% 14.8%caused by sheath wilt and ear blight complex,and at 11.7% 51.5%and 12.1% 18.3%by sheath wilt and ear blight and leaf spot complex respectively.
