【摘要】 1991～1999年在福建省惠安等地,对51个不同木麻黄地理种源进行抗虫序列调查、室内外人工接虫（星天牛）、抗虫种源的繁殖育苗技术、营造抗性品系示范林、抗虫机理测定等系列研究,根据其抗虫、保存率、生长量、抗风稳定性等指标,综合评判出木麻黄种源 C₃₈、C₃₉、C₄₀、C₄₃和 C₄₄为高抗种源。对高抗种源在林间持续调查9a,星天牛后期蛀入木质部的虫株率均为0%;而感虫种源 C₂₃虫株率（1991～1993年）平均高达52.7%。1998年起建立了抗性种源采穗圃,向沿海各县市提供较大数量的无性繁殖木麻黄水培苗。更多还原

【Abstract】 Pest resistance sequence of Casuarina spp.from 51 geographical provenances was investigated in Huian etc.from 1991～1999.Artificial inoculation（insect）indoor and outdoor,seedling cultivation and breeding techniques,establishment of demonstration forest for resistant strains,measurement of mechanism of pest resistance were conducted.On the basis of index of pest resistance,survival rate,growth and stability to wind,were determined provenances of Casuarina spp.C₃₈,C₃₉,C₄₀,C₄₃,and C₄₄as high resistance provenam- ces,that were investigated sequentially for 9 years.Rate of plant with peat insect boring into xylm was 0%, while that of pest-affected provenance C₂₁was up to 52.7%（1991～1993）。Since 1998 the cutting orchard for resistance provenance has established and provided clonal breeding seedlings in water culture to coastal re- giens.更多还原
