摘要:
以薄壳山核桃12个品种的种子为试验材料，测定种子长、宽、高、单粒质量、密度等形态外观指标，并通过发芽试验，研究种子形态指标、发芽特性和幼苗长势之间的相关性，从而筛选优良品种。结果表明：(1)来源于薄壳山核桃不同产区的种子，其形态、萌发和幼苗初期生长的相关性存在一定的差异；(2)种子外观形态对种子发芽和生长的相关性总体上不大；(3)推荐‘Desirable’和‘Kanza’作为薄壳山核桃砧木进一步引种、栽培和推广。
Abstract:
To screen different pecan cultivars with strong seed germination ability and seedling growth ability, and to provide trial reference for Jiangsu pecan seedling rootstock breeding and cultivation, this study made a comparison of seed germination between different pecan cultivars. Pecan seeds of 12 cultivars from North America were used as experimental materials, and the morphological indices such as seed length, width, height, weight and density were measured, and the seed germination and seedling growth characteristics were studied. The results showed that there were some differences in the seed morphological characteristics, germination and seedling growth originated from different areas. In addition, pecan seed morphological characteristic had little effect on seed germination and growth. From the comprehensive comparison, ‘Desirable’ and ‘Kanza’ were selected as the optimal rootstocks, suitable for further introduction, cultivation and extension.
