| 摘 要： | 以萌发种子根尖为材料,对9份甜瓜近缘植物和1份野甜瓜进行了染色体计数。结果表明:绝大部分试验材料的体细胞染色体数目为2n=24,与栽培甜瓜体细胞染色体数目相同,但在西印度瓜材料中发现体细胞染色体数2n=48、迪普沙瓜材料中出现体细胞染色体2n=44的现象。从甜瓜属植物染色体基数为7或12的分类出发,迪普沙瓜体细胞染色体2n=44不符合甜瓜属植物的染色体基数特征,可能与该材料栽培过程中染色体产生自然加倍和缺失有关。

| Abstract: | The root s of germinating seeds were used to study on chromosome counts of nine melon relative pants and one wild melon plants.The results showed that chromosome number in somatic cells of most materials were 2n=24,equal to melon chromosome number,except one accession C.anguria with 48 chromosomes and one accession C.dipsaceus with 44 chromosomes in somatic cells,the latter was not according to base chromosome numbe x=7 or x=12 in Cucumis,maybe whose chromosomes had spontaneous duplication and deletion duri... |
