| 摘 要： | 选用1个叶菜型甘薯品种和5个普通甘薯品种为材料,采用分期采摘茎尖的方法,比较分析了不同类型甘薯品种的茎尖重量及形态结构.结果表明,叶菜型甘薯品种百薯1号茎尖重量的变异系数最小,普通甘薯品种以徐薯18茎尖重量的变异系数最大;各品种茎蔓重、叶片重、叶柄重占茎尖重量的百分比存在一定差异,叶菜型甘薯品种百薯1号茎蔓比例最小,叶片比例最大,叶柄比例较大;叶莱型甘薯品种百薯1号的茎蔓、叶柄最细,其叶柄长度与5个普通甘薯品种的平均叶柄长度十分接近.

| Abstract: | 1 kind of leaf-vegetable sweet potato cultivars and 5 kinds of common sweet potato cultivars were selected in 2007,to compare their stem tip weight and morphological structure.The result indicated:(1)Variation coefficient of tip weight with leaf-vegetable sweet potato Baishu 1 was the lowest,and the biggest one was from common sweet potato Xushu18.(2)The percentages of stem weight,leaf weight and petiole weight accounts for tip weight existed certain difference with all cultivars,stem proportion was the sma... |
