摘　　要：以南京地区7株薄壳山核桃单株果实为研究对象,通过测定果实大小、出仁率、粗蛋白质、可溶性糖、水分、灰分、粗脂肪和淀粉含量等指标,研究其果实品质并进行发芽试验比较发芽特性,以期为薄壳山核桃的良种选育、品种改良及良种推广提供基础参考依据。结果表明:不同单株的果实品质存在显著差异;果实出仁率是影响种子发芽率的重要指标;淀粉与幼苗长势呈显著正相关;分析选育出5号单株为培育砧木苗的最优单株,适宜作为南京地区优良单株进行培育和推广。In order to provide reference base for fine cultivar breeding,cultivar improvement and seed extension of Carya illinoinensis,seeds of seven individual pecan trees were collected.Its nut quality by the nut size,kernel percent,crude protein,soluble sugar,moisture content,ash,crude fat and starch content were evaluated.Also,the germination characteristics was evaluated.The results showed that there was significant difference in fruit quality.The fruit kernel percent significantly influenced the germination rate,and seedling growth quality was significant positively related to starch.For this study,the No.5individual Carya illinoinensis tree was recommended as the best one to breed and extend in Nanjing area.
