这篇英文文章翻译，恳请高手指正 -------------- Freeze-dried seeds really last 冻乾法真能延长种子寿命 When Lowell Woodstock returned in 1978 after two years in Saudi Arabia, he found that all the freeze-dried onion seeds he had left from earlier freeze-drying experiment were viable, while more than half the air-dried seeds were not. Woodstock, a plant physiologist with the Agricultural Research Service, who kept the freeze-dried seeds for seven more years of storage at room temperature and 40-50°C, found little sign of deterioration. 在沙乌地阿拉伯待了两年後，Lowell Woodstock於一九七八年回到美国。他发现先前以冻 乾法实验所保存的洋葱种子，能够继续成长，而有一半以乾燥法保存的种子则不然。 Woodstock是一位植物生理学家，任职於美国农验研究服务处。他将种子以冻乾法的方式 ，保存在室温，以及摄氏40到50度的房间长达七年多，却发现种子没有坏掉的迹象。 The original research in 1976 showed that freeze-drying markedly improved storage life of onion, pepper, and parsley seeds at temperatures equivalent to those in tropics and subtropics. Woodstock says freeze-drying works very well in combination with air-drying. First, seeds are air-dried to about 10 percent seed moisture and then freeze-dried down to 5 percent. 最初在一九七六年，研究指出在温度近似热带、亚热带的环境，以冻乾法保存的洋葱、辣 椒、荷兰芹种子的保存期限，都大幅增加。 Woodstock指出冻乾法和乾燥法可说是相辅相成。首先，以乾燥法将种子的湿度降至百分 之十，接着再以冻乾法降至百分之五。 Air-drying can easily reduce seeds to about 10 percent, but after that point it becomes difficult, requiring either high or prolonged heat, both of which can damage seeds. Woodstock believes that onion seeds and possibly other vegetable seeds dried by this two-step method can be selected in moisture-proof packets and stored for many years at room temperature or indefinitely at sub-freezing temperatures. 因为乾燥法可以轻松将种子湿度降至百分之十，但，要再往下降可就没那麽容易。你需要 高温或是长温来使种子脱水，而这两种方法都会让种子死去。 Woodstock相信，除了洋葱种子外，冻乾法及乾燥法还可能运用在其他植物种子。接着， 选出品质较好的种子进行防潮包装，在室温环境可以保存数年，而在零度以下的环境则可 以永久保存。 ---- 麻烦高手不吝赐教! --
