摘　　要：通过黑穗病接种的方法,对甜高粱正常植株与黑穗病株的株高、鲜重、含糖量、出汁率及抽穗期进行调查和测定。结果表明,黑穗病株的株高和鲜重都低于正常植株,差异大小因品种而异;黑穗病株的含糖量及出汁率有的提高,有的降低,因品种而异;黑穗病株的抽穗期都早于正常植株。Plant height,fresh weight,stem sugar content,stem juice ratio and heading date of smut and smut-free plants were investigated after smut inoculation.The results indicated that plant height and fresh weight of smut plants were lower than normal plants.The differences varied from variety to variety.Some smut plants’ stem sugar content and juice ratio were higher than normal plants’,but some were lower.Heading date of smut plants was earlier than that of normal plants.
