摘    要:油松是我国北方的重要造林树种,由于因长期受自然环境的影响,不同地理种源的生长特性各异。为了解种源间的生长差异,调查了30份油松种源的2年生苗高和地径生长动态,结果表明:油松苗高和地径在种源间均存在极显著差异,种源16的苗高最大为15.4 cm,地径最大为4.77 mm。综合评价苗期生长情况,油松种源16和18较好。

关 键 词:油松  种源  遗传变异性  生长特性

Abstract:Pinus tabulaeformis is an important forestation species in northern China, and different geographic provenances of this species had different growth characteristics due to the long-term influence of natural environment.In order to understand the growth differences among various Pinus tabulaeformis provenances, we investigated the height and ground diameter growth dynamics of 2-year-old seedlings of 30 Pinus tabulaeformis provenances.The results revealed that there were very significant differences in both seedling height and ground diameter among 30 provenances.The provenance No.16 of Pinus tabulaeformis had the highest seedling height and the biggest ground diameter, being 15.4 cm and 4.77 mm respectively.The comprehensive evaluation of seedling growth situation showed that the provenance No.16 and the provenance No.18 of Pinus tabulaeformis were better than the others.
Keywords:Pinus tabulaeformis  Provenance  Genetic variation  Growth characteristics
