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.

This article is from ECHO Asia Note #28 對于熱帶地區的農民和研究人員，種子儲存是非常令人沮喪的。在蒙多基里省，從收獲到新的種植季 節期間農民基本不能把種子保存超過 6 個月。種子儲存的時間如果長于 6 個月，就會在濕季從潮濕的空氣 中吸收很多濕氣失去活性，或者遭受病蟲害使種子繁殖性和外形遭到破壞。在我們的研究中心，我們已經 建立了一個很多有用的種子品種的存貨清單，不需要每一年都種出每個品種。但是，與農民類似，我們的 種子經常很快就失去了活性或者在儲存中被害蟲破壞。 冷藏和冷凍是眾所周知的大多數傳統種子延長種子壽命的方法，(參見 ECHO 亞洲期刊...
