摘要
以5大类型的24个玉米材料为试验对象,对微胚乳超高油玉米(微胚乳玉米,MEM)成熟子粒的显微结构进行了初步研究,通过这些玉米材料的胚重/子粒重比值的分析,进一步探讨微胚乳玉米材料与其它4大类非微胚乳玉米材料的显微结构的差异。显微观察结果显示:微胚乳玉米材料的胚乳含量很少,有些材料甚至不含胚乳(除糊粉层外),说明微胚乳玉米材料的胚乳存在不同程度的解体。但它们的胚却是5大类玉米材料中最大的。同时,微胚乳玉米材料的胚重/子粒重比值也是5大类玉米材料中最大的。
Twenty four lines of 5 types maize were used to study the micro-structure in ripe kernel of MEM（micro-endosperm super high oil maize）, weight ratio of embryo to kernel, and the different characteristics of microstructure between MEM and the other 4 non- MEM. The results indicated that the endosperm contents of MEM were very few. Some of them even had no endosperm（except aleurone layer）. It illustrated that some of the MEM showed degenerative endosperm, but their embryos were the biggest among the 5-type maize. At the same time, the weight ratio of embryo to kernel of MEM was also the maximum in 5-type maize.
