| 摘 要： | 试验研究了不同类型甜玉米籽粒发育过程中糖分积累的差异 .结果表明 :在各采收期总糖含量以超甜玉米最高 ,加强甜次之 ,普通甜玉米最低 ;随发育进程的不同 ,普通甜玉米、超甜玉米和加强甜玉米的还原糖含量、蔗糖含量、水溶性多糖 (WSP)含量以及水分含量的变化趋势基本相同 ,可溶性糖含量与蔗糖含量相一致 .依籽粒水分含量和糖分积累规律确定的适宜采收期 ,普通甜玉米以授粉后 18～ 2 1天为好 ,加强甜玉米相对延长 ,超甜玉米则宜适当推迟 .

| Abstract: | The accumulation of sugar content of different varieties in sweet corn was studied.The results showed that the content of total sugar of super sweet corn,during harvesting stage,was the highest,followed by streng then sweet corn and sweet corn.The trend of reducing sugar content,sucrose content,water soluble polysaccharoses content (WSP) and water content were similar among the three types of sweet corn.Based on sugar accumulation and water content,the optimum harvesting period was at 18 to 21 days after pollination for sweet corn,at 20 days after pollination for super sweet corn. |
