中文摘要：
为选育和栽植优质山药品种,以5种山药为研究对象,进行叶形、叶脉、叶面积及抗氧化活性等方面研究。结果表明：参薯SH01的革质厚叶,叶色墨绿;参薯SH02的黄绿色心型叶片;参薯SH03箭头型叶形;参薯SH04披针型叶片;山薯SH05叶片发皱。在叶片抗氧化酶活性方面,SH01具有最高含量的可溶性蛋白质、SOD和APX,SH04具有最高的CAT活性,SH02具有最高活性的POD。综合抗氧化酶活性比较,SH01具有比其它品种更高的抗氧化活性,表现出更强的抗逆性。
英文摘要：
In order to breed and plant high quality Dioscorea L.varieties,taking five kinds of Dioscorea L.as materials,the leaves characteristics and antioxidant enzyme activities were studied.The results showed that SH01 had thick leathery leaves with the color of dark green;SH02had heart-shaped leaves with the color of chartreuse;SH03had the average maximum leaves and arrow-shaped leaves,which were different from other varieties;SH04had lanceolate shaped leaves;SH05had the wrinkled leaves.In leaf antioxidant activity areas,SH01 had the highest content of soluble protein,the highest activity of SOD and APX,SH04 had the highest CAT activity;SH02had the highest activity of POD.Comprehensive comparison of antioxidant enzyme activity,SH01 was higher than other varieties of antioxidant activity and showed stronger resistance.
