摘要
研究以纸浆和矿柱工业用材为目的５个苏柳无性系（Ｊ７９９，Ｊ７９５，Ｊ９０３，Ｊ８０２，Ｊ３０８）的生长、干形及适应性，用苏柳１７２为对照。结果表明，Ｊ７９９和Ｊ９０３无性系生长量大于Ｊ１７２。干部溃疡病和天牛危害较轻，无性系×地点互作较显著，Ｊ７９９适宜在湖滩淤积地造林，Ｊ９０３适合在河滩冲积地造林。Ｊ７９５无性系树干端直，弯曲度小。
The growth, truncal form and adaptation of 5 Salix × jiangsuensis clones(J799,J795,J903,J802,J308) for pulp and pitwood have been comparatively studied with Salix jiangsuensis CL ‘J172’ as CK.The increment of J799 and J903 is larger than J172, their resistance to canker and Rhabdophaga sp. is also much stronger. It is significant that clone×location, J799 could be planted on lake beach, but J903 is better to planting on river beach. J795 trunk is much straighter than other clones, so its qualified percentage of pitwood is higher too
