中文摘要：

通过脱水速率对不同发育阶段的非洲柚种子脱水耐性影响的研究，其结果表明：花后130d，190d，245d和275d的非洲柚种子在慢速脱水的条件下具有比快速脱水更强的脱水耐性，而且差异显著（P〈0．05）。但对于花后155d和220d的非洲柚种子，快速脱水和慢速脱水条件下脱水耐性差别变小，未达到显著性水平；脱水速率对非洲柚种子脱水耐性的影响与种子的发育阶段有关。这样的结果与前人以正常性大豆种子和玉米胚为材料得到的结果相类似。研究认为，脱水速率对中间型非洲柚种子脱水耐性的影响，可能主要在于慢速脱水能够诱导某些与脱水耐性相关的蛋白的表达和积累。慢速脱水诱导脱水耐性必需以种子具有相应的遗传基础为前提，而且需要选择合适的时机。

英文摘要：

The effects of drying rates on the desiccation tolerance of Citrus maxima ＇ Feizhouyou＇ seeds at different developmental stages were studied in this paper. For seeds harvested at 130 days after anthesis （DAA） , 190 DAA, 245 DAA and 275 DAA, slow-dried seeds had higher desiccation tolerance than those rapid-dried, with difference at significant level （P 〈 0. 05）. However, such improvement was little for seeds harvested at 155 DAA and 220 DAA, indicating that effect of drying rate on desiccation tolerance depends on seed developmental stages. These results ac-corded with previous reports on orthodox soybean seeds and maize embrys. It was suggested that the effects of drying rate on desiccation tolerance of intermediate Citrus maxima ＇ Feizhouyou＇ seeds mainly resulted from expression and accumulation of some desiccation-related proteins induced by slow drying. On the required genetic basis, desiccation tolerance in seeds can be induced only at suitable seed developmental stages.
