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。
The drought--resistance and the characteristics of plant pattern were analyzed and compared 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 I, Longdan 26,Nendan 11 and Sidan 19 . The identification Indexes of drought-resistance can be used in spring maize ,they were ①the amounts of the radicle , ②the height of the plant , ③the size of the ASI, ④the volume of the degree green-preserve.
