| Abstract: | The indexes of drought-resistance identification were compared on the common varieties of spring maize all in the shed of drought-resistance,the plot,the field.The results showed that among the drought-resistance identification in maize,the number of the radicle,the height of the plant,the size of the ASI,the volume of the degree green-preserve,the coefficient of drought-tolerant,RI,and RI(amendment) can be used as identification indexes on drought-resistance of spring maize. |
