摘要: 本研究选择了在我国主要桉树种植区内种植面积大或具有推广潜力的12个优良桉树品系,在广东肇庆、阳江和湛江3个样地进行抗桉树枝瘿姬小蜂试验,结果表明M1(Eucalyptus urophylla×E. tereticornis)、雷9(E. urophylla×E. tereticornis)为高抗品系,DH3229(E. urophylla×E. grandis)、DH3228(E. urophylla×E. grandis)、DH3226(E. urophylla×E. grandis)、LH1(E. urophylla×E. tereticornis)、金光21(E. jinguang No.21)、广3(E. wetarensis×E. marginata)和广林9(E. grandis×E. urophylla)等7个品系为抗虫品系,邓恩桉(E. dunnii)和雷11(E. urophylla×E. tereticornis)为感虫品系,Eg5(E. grandis)为高感品系。不同品系的感染虫瘿数量差异显著,Eg5的丛枝状等级较其它品系高,其它11个品系间的丛枝状等级也表现出不同程度的差异。

Abstract: Twelve eucalyptus strains that show great potential for plantation or have already been cultivated widely inChina were collected and planted in three plots (Zhaoqing, Yangjiang and Zhanjiang of Guangdong province) for testing resistance to Leptocybe invasa Fisher & La Salle. Results suggested that M 1 (Eucalyptus urophylla×E. tereticornis) and Leizhou 9 (E. urophylla×E. tereticornis) were highly resistant strains, seven strains including DH3229 (E. urophylla×E. grandis), DH3228 (E. urophylla×E. grandis), DH3226 (E. urophylla×E. grandis), LH1 (E. urophylla×E. tereticornis), Jinguang 21(E. jinguang No. 21), Guangzhou 3 (E. wetarensis×E. marginata) and Guanglin 9 (E. grandis×E. urophylla) were resistant strains, while E. dunniiand Leizhou 11 (E. urophylla×E. tereticornis) were susceptible strains, and Eg5 (E. grandis) was highly susceptible strain. Significant differences in gall numbers and grade of fascicled symptom were recorded between eucalyptus strains.
