龙眼(Euphoria Longna Lam)、枇杷(Eriobotrya japonica Lindl)原产我国,是当今很受欢迎的水果。长年进化使得品种(系)非常丰富,仅本所栽植的种质(龙眼、枇杷)已分别达二百多份。我们在对种质主要性状鉴定的基础上拟利用染色体这个稳定的遗传因子来作为一种鉴定手段。植物染色体制片,方法很多:材料上有用的根尖、茎尖、嫩叶、子叶等;方法上有
Longan (Euphoria Longna Lam), loquat (Eriobotrya japonica Lindl) originated in China, is today’s popular fruit. The long years of evolution have led to a great variety of varieties (lines). Only the germplasm (longan and loquat) planted here has more than 200 respectively. Based on the identification of the main traits of germplasm, we intend to use the stable genetic factor of chromosome as a means of identification. Plant chromosomes, many ways: the material useful root tips, shoot tips, young leaves, cotyledons, etc .; methods have
