| 摘 要： | 对新疆57个杨树种、品种(无性系)的腐烂病Cytospora chrysosperma (Pers.) Fr.病情指数和相对抗性指数进行了调查和分析。结果表明:供试的57个种、品种(无性系)除三倍体毛白杨外在造林初期均发病较轻,病情指数0.00～9.72,相对抗性指数65.98～100。通过差异显著性分析,不同杂交组合的相对抗性指数存在差异,但在多数杂交组合间差异不显著,同一杂交组合的不同品种(无性系)抗病性出现分化,部分品种(无性系)间的相对抗性指数存在显著差异。高感的种、品种(无性系)有三倍体毛白杨,低抗的种、品种(无性系)主要有准葛尔1号20、南林2141,中抗的种、品种(无性系)有天演杨、南林2144、南林106-南林105、栅栏杨、90-ⅡC15,其余49个种、品种(无性系)均表现为高抗。

| Abstract: | Infection and resistant indices of 57 poplar species or varieties(clones) in Xinjiang with Cytospora chrysosperma(Pers) Fr.were investigated.The results indicated that except for triploid Populus tomentosa,all the poplars were slightly infected with the desease in the initial afforestation stage,with the infiction index ranging from 0.00 to 9.72,and relative resistant index ranging from 65.98 to 100.There was no significant difference among the resistant indices of different hybridized combinations,though t... |
