杉木是我国分布较广的树种之一。为了解不同产地的杉木对气候、土壤的适应性及速生丰产的能力和抗病虫害、抗冻害的能力,为当地选择高产优质的最适种源,我们开展了种源试验。本文根据苗期和一年生幼林在我场生长情况,进行初步整理,供作参考。一、材料和方法本试验由南京林学院育种教研组主持。材料包括11个省的19个种源和本场初级种子园、母树林的种子,共21个种源(列表一)。种源种子要求由30株20年左右的健康母树上采集,
Chinese fir is one of the widely distributed species in China. In order to understand the adaptability of climatic conditions in different areas and the ability of fast-growing and high-yielding, and the ability of anti-pest and frost-resistance to the climatic conditions, we conducted provenance tests to select the most suitable provenances for high yield and quality in the area. Based on the seedling growth and annual growth of young forest in my field, the preliminary arrangement for reference. First, materials and methods The experiment by the Nanjing Forestry College breeding teaching and research group presided over. The material includes 19 provenances from 11 provinces and seeds from this primary seed orchard and a total of 21 provenances (List 1). Seed germination requirements from 30 20-year-old healthy mother tree collection,
