三个不同组合的马铃薯实生种子分别播在含有0(CK),0.2%,0.4%和0.6%NaCl处理的土壤和MS培养基中,以调查NaCl对实生种子发芽以及生长发育的影响。结果表明:随着基质中盐浓度的增加,实生种子生长受到抑制就越厉害,土壤中盐浓度达到0.4%时,幼苗的存活率仅为14.3%~27.8%,达到0.6%时幼苗全部死亡;MS培养基中盐分达致电0.4%时,幼苗的存活率为40%~46.7%,达到0.6%时为10%~23.3%。笔者认为从实生种子中筛选抗(耐)盐品种(系)应先从培养基中开始,做初步淘汰工作,为最终的田间筛选节约大量的时间和工作.
Three different combinations of potato seed were sown in soil and MS medium containing 0 (CK), 0.2%, 0.4% and 0.6% NaCl, respectively, to investigate the effect of NaCl on seed germination and growth of the seed Developmental effects. The results showed that with the increase of salt concentration in the matrix, the growth of the seed was more inhibited. When the salt concentration in the soil reached 0.4%, the seedling survival rate was only 14.3% -27.8%, reaching 0 .6% of all the seedlings died; the survival rate of the seedlings was 40% -46.7% when the salt content in MS medium reached 0.4%, and it was 10% -23.3% at 0.6%. The author believes that screening anti-(salt) resistant varieties (lines) from seed should start with the medium and make preliminary phase-out work, saving a lot of time and work for the final field screening.
