摘  要:
为进一步确定玉米的耐旱指标,有效地进行新品种的选育,以黑龙江省农业科学院玉米研究所高产室选育的相对耐旱玉米新品种龙单23和相对不耐旱的龙343为试验材料,分析和比较了不同类型玉米品种的生长状况差异。结果表明:较耐旱品种龙单23在不同的水分条件下的根干重、根冠比值、根长、根数等参数都明显优于相对不耐旱品种龙343。

摘  要:
In order to determine the drought index of maize for the new varieties breeding effectively,taking drought resistant maize new chamber relative of Longdan 23 and relatively drought dragon 343 as experimental material from Heilongjiang Academy of Agricultural Sciences,institute of corn high yield breeding,under the different water conditions the characteristics of individual differences were studied and analyzed.The results showed that the root dry weight,root-shoot ratio,root length and root number of Longdan 23 were all better than Long343 under different water conditions.
