采用PEG-6000溶液在0、5%、10%、15%、20%的浓度下胁迫10份青贮玉米自交系,测定了在干旱胁迫下青贮玉米的相对发芽率、相对胚芽长度、相对胚根长度、相对株高和相对含水量,综合评价供试材料芽苗期耐旱性。结果表明,各供试材料间耐旱性差异显著,其中7922的综合评价值为0.9402,耐旱性最强;其他各材料综合评价值为0.5～0.8,抗旱耐旱性弱。

The relative germination ratio, relative embryo-bud length, relative embryo-root length, relative plant height and relative water content were investigated to determine the effect of drought stress on 10 inbred lines of silage maize treated with different concentrations of 0, 5%, 10%, 15%, 20% by PEG-6000. The results showed that the 7922 had the strongest drought tolerance in tested pieces with the evaluated value of 0.9402; others tested pieces were poor in the salt tolerance with evaluatd value ranging between 0.5 and 0.8.
