摘要
常用于贮存种子的低温温度,高的可达10至15℃,低的可到-20℃,但-40℃能否用来贮存种子?贮存的效应如何?这方面的研究报导还较少见。由于制冷技术的发展进步,-40℃的低温设施日渐增多,为探讨-40℃低温在大白菜和大葱种子上的贮存效应,我们进行了三年的密封贮存试验,结果表明-40℃低温可用于上述蔬菜种子的贮存,并且具有与-20℃相似或更好的保存效果。
The low temperature ofen used in seed storage is between in-20℃ to 15℃,there are few reports in whether-40℃ can be applied and what effect it will be. As the development of the refrigeration temchnique, the-40℃ low teperature equipments are becoming more and more, in order to approach the effwct on-40℃ seeds storage of Chinese cabbage and welshonlon. We heve been testing this storage experiment for three years. The study results show: These seeds can be stored in low temperature of-40℃. As compared with-20℃...
