英格兰约翰英纳斯的科学家们正在开发花椰菜新品种,该品种能够快速生长,从发芽到收获只需8~10周。新品种能够使其在田地种植时实现一个季度两次收获;同时随着种植农户不再依赖于季节性天气条件,可以实现花椰菜在受保护条件下的全年种植,从而保障连续性的供应。我们常吃的花椰菜其实是它的花蕾部分。春化是一些植物在开花之前必须经历低
Scientists at John Innes, England, are developing new varieties of cauliflower that can grow rapidly, from germination to harvest in just 8 to 10 weeks. The new variety enables it to be harvested twice a quarter of the time in the field; at the same time, the cauliflower can be planted throughout the year under protected conditions as the farmer no longer depends on the seasonal weather conditions to ensure a continuous supply. The cauliflower we eat is actually the bud part of it. Vernalization is that some plants must experience low flowering
