摘要
芒果种子离体胚轴的耐脱水力大于其整粒种子的耐脱水力，经硅胶脱水至１１％含水量时仍有７０％发芽率。５％～１０％的蔗糖和脯氨酸预处理可在一定程度上提高芒果离体胚轴的耐脱水力，但效果不显著。含水量为８．７％～３８．６％的干燥离体胚轴经液氮（一１９６℃）贮藏２４ｈ后，生活力完全丧失。
Exicised embryonic axes of mango(Mangifera indica)seeds were more tolerant todesiccation than their whole seeds.After being desiccated to 11% moisture content,70 % of excised embryonic axes could germinate on culture medium. To some extent,pretreatment with 5 %～10%sucrose or proline could increase the tolerance of ex-cised embryonic axes to desiccation,but the result was not obvious.Excised embryon-ic axes with different moisture content(from 8.7 % to 3 8.6%)lost their viability entire-ly after storage in LN2 for 24 hours.
