- 摘要:
- 引种是优质种质资源扩大栽培区域的重要方法。为探究魔芋在哈尔滨市呼兰区的引种适应性,以花魔芋为试验材料,采用田间栽培法,并采用3,5-二硝基水杨酸方法测定了魔芋葡甘聚糖含量。结果表明:魔芋地下球茎在本地区年生长期约168 d,种球膨大系数最高可达3.48,二年生魔芋葡甘聚糖含量为56.45%,三年生魔芋葡甘露聚糖含量为64.35%。说明魔芋可在哈尔滨市呼兰区推广种植,二年生魔芋适合作为种球。
- Abstract:
- Introduction is an important method to expand cultivation area of high quality germplasm resources.In order to explore the adaptability of konjac in Hulan district of Harbin City,field cultivation method was used to study the growth of konjac in Hulan district of Harbin City,and the content of konjac glucomannan was determined by 3,5-Dinitrosalicylic acid method.The results showed that the annual growth period of Konjac underground corms was about 168 days,and the highest coefficient of bulb expansion was 3.48.The content of konjac glucomannan was 56.45% in biennial and 64.35% in triennial,which indicated that konjac could be popularized and planted in Hulan district of Harbin City.The biennial konjac was suitable for breeding bulb.
