Seeds naturally have a place in almost any endeavor having to do with agricultural development. Seeds of most food plants are small and, as such, are more easily transported and can be shipped longer distances than vegetative cuttings. For the farmer, seeds represent the promise of a continued supply of food.
As with any development “tool,” however, seeds can be misused. For instance, distributing improperly stored seeds that germinate poorly could expose farmers to risk of crop failure.

关键资源 This article is from ECHO Asia Note #27 种子储存的原则 当要建一个“冷藏室”或“种子储藏室”来达到保持种子活性的目的时，最先要考虑的种子储存的最佳条件。在ECHO 亚洲期刊14（ECHO Asia Note 14）（2012 年6 月），我们分享了真空密封和冷藏的对比结果，并强调对于种子储存湿度和温度控制的重要性。我们发现湿度控制（真空密封）比温度控制（冷藏）更有效地保存种子活性。在这个ECHO 亚洲的实验中，热带种子最佳的储存方式是干燥后（为了保持较低的种子湿度）立刻真空密封，然后把种子储存在较低的温度之下。要设计一个最适宜种子储存的冷藏室，...

This article is from ECHO Asia Note #28 对于热带地区的农民和研究人员，种子储存是非常令人沮丧的。在蒙多基里省，从收获到新的种植季 节期间农民基本不能把种子保存超过 6 个月。种子储存的时间如果长于 6 个月，就会在湿季从潮湿的空气 中吸收很多湿气失去活性，或者遭受病虫害使种子繁殖性和外形遭到破坏。在我们的研究中心，我们已经 建立了一个很多有用的种子品种的存货清单，不需要每一年都种出每个品种。但是，与农民类似，我们的 种子经常很快就失去了活性或者在储存中被害虫破坏。 冷藏和冷冻是众所周知的大多数传统种子延长种子寿命的方法，(参见 ECHO 亚洲期刊...

关键资源This article is from ECHO Asia Note # 37. 在亚热带和热带种子储存是一项挑战。如果没有干燥和冷环境，种子的质量可能会急剧恶化。储藏时的高温高湿会加速种子的新陈代谢并且促使食种虫增殖（Lale and Vidal, 2003; Upadhyay and Ahmad, 2011）。冰箱、除湿机和杀虫剂等技术能防止这些毁坏种子的情况发生，但是热带地区的小型农户不一定能利用这些技术。很多当地传统方式被用于防止虫害。一些处理剂通常在种子储存前添加到种子中，为了毒杀害虫，或者破坏和阻止昆虫在种子周围移动。一些处理剂能非常有效地减少害虫生长，...
