中文摘要:
      为了解两个地理种源镇沅(ZY)和墨江(MJ)豆腐渣果的果实特征规律,对72份豆腐渣果果实的若干外观和数量性状进行了鉴定评价。同时,以豆腐渣果的幼苗为砧木,利用澳洲坚果3个品种的芽条进行嫁接,观察嫁接成活率,以初步探索山龙眼科种质资源亲缘关系的开发利用前景。结果表明,在外观性状上,两种源豆腐渣果的果实均以绿色为主;但在果皮质地上有所差异,镇沅的果皮多较光滑,而墨江的全部为粗糙质地。两种源豆腐渣果除出苗率(镇沅75.39%和墨江83.26%)无显著差异外,墨江的其他数量性状指标均显著高于镇沅的;8个数量性状中,果实单果重和果形指数对两种源样本累积贡献率分别为79.47%和96.23%。经各项指标代入综合评分模型,从72份样本中选出了15个果实综合性状优良的样本,可考虑进行种质资源开发利用。初步嫁接试验结果表明,澳洲坚果芽条与豆腐渣果幼苗砧木二者表现为嫁接不亲和。
英文摘要:
      To understand the fruit traits and pattern of Helicia nilagirica Bedd. from two geographical provenance, ZhenYuan(ZY)and Mo Jiang(MJ), we analyzed a number of fruit appearance and quantitative characters. Meanwhile, grafting experiments were made with H. nilagirica seedlings as the stock and three varieties of Macadamia ternifolia F. budling as the scion to preliminarily explore their graft compatibility. The results showed that most fruits were green in color,both for ZY and MJ H. nilagirica. The pericarp of ZY H. nilagirica was mostly smooth, while the pericarp of MJ H. nilagirica was overall rough. The seedling germination rate between the two provenances(ZY 75.39% and MJ 83.26%)was similar, but in other quantitative characters MJ H. nilagirica was significantly higher than ZhenYuan H. nilagirica. Among the 8 quantitative characters, the cumulative contribution rate of single fruit weight and fruit shape index reached 79.47% and 96.23% respectively. Putting the indices into the comprehensive evaluation model, from 72 plant samples, 15 plant samples with excellent fruit comprehensive characters were selected, which could be considered to be used in the development and utilization of germplasm resources. The grafting experiment showed the H. nilagirica seedlings were incompatible with Macadamia ternifolia F. bud.
