湖北恩施种源红椿不同家系育苗试验初报

Primary Study on Seedlings of Toona ciliata Different Families of Enshi Hubei Provenance

摘要:

摘要：为了给湖北乡土树种红椿资源保护及开发利用提供基础数据，本研究以湖北恩施的6个红椿半同胞家系为材料，对其1年生实生苗木进行了生长量调查和分析，结果表明，6个不同红椿家系间当年生苗高、地径、叶长、叶宽、叶长宽比的差异均达到了显著水平，其中表现较好的是红椿2和3号家系。本研究取得的苗期生长数据在一定程度上客观反映了恩施红椿种源在武汉地区的适应性，可为今后武汉周边地区发展利用红椿提供良好借鉴。

Abstract:

Abstracts:Aiming to provide the basic data for protection and development and utilization of Hubei native Toona ciliata resources, the investigation and analysis of growth data of one year old seedlings of 6 half sib families of Toona ciliata from Enshi Hubei had been done. The result indicated that there were significant differences about seedling height, ground diameter, leaf length, leaf width and ratio of leaf length to width in 6 families, between them with better performance were the second family and third family. The data obtained in this study to a certain extent objectively reflected the adaptability of Toona ciliata from Enshi provenance in Wuhan region, and could provide a good reference for the future development in Wuhan surrounding areas.
