  3. 关键资源 This article is from ECHO Asia Note # 37. Seed saving in sub-tropical and tropical climates is challenging. Without equipment designed to maintain dry and cool environments, the quality of seeds may quickly deteriorate. High temperature and humidity during storage increase seed metabolism and...

    2010-06-01 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.

Orthodox seeds are...
  6. 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,...
  7. 2019-01-20 Given the proper facilities necessary to store seeds long-term, whereby low temperature and low humidity are kept stable over time, it is very possible to store most orthodox seeds for several years at a time in the tropics (Harrington, 1972). Unfortunately, implementation and maintenance of the...

  9. 2020-01-27 This article summarizes several methods with which I have experimented to control various types of weevils in stored seed. Seed containers can range in size from small jars to barrels/drums, but must be airtight for these techniques to work. The techniques are relevant for seeds being stored for...
