【摘要】 利用抗旱棚盆栽、小区、大田对春玉米常规品种的抗旱性及形态特征进行比较分析。结果表明:抗旱性强弱顺序是嫩单10号、兴垦3号、金玉2号、嫩313、嫩单8号、龙单13、九玉1号、龙单26、嫩单11、四单19;在玉米抗旱性形态特征中,①胚根数的多少、②植株的高矮(适当高度)、③ASI的大小、④保绿度的高低可作为春玉米抗旱性的形态鉴定指标。更多还原

【Abstract】 The drought-resistance and the characteristics of plant pattern were analyzed and com-pared on the hybrids of spring maize both in the shed of drought-resistance,the plot and the field.The results showed that the ranking of drought-resistance from strong to weak among the hybrids was:Nendan 10,Xingken 3,Jinyu 2,Nen 313,Nendan 8,Longdan 13,Jiuyu 1,Longdan 26,Nendan 11 and Sidan 19.The identification Indexes of drought-resistance can be used in spring maize,they were①the amounts of the radicle,②the height of the plant,③the size of the ASI,④the volume of the degree green-preserve.更多还原
