解析 B. planting the seeds 该题目考察的是农业生产的顺序。选项A“收割小麦”、选项B“播种”和选项C“烘焙面包”都是农业生产中的步骤,但顺序不同。播种是农业生产的开始,收割小麦是收获阶段,烘焙面包则是食品加工环节。因此,最合理的答案是 B. planting the seeds,因为播种发生在收割小麦和烘焙面包之前。

Cappelle Desprez wheat indicated that infected plants yield about 30 per cent that of healthy plants, but much of this yield consists of very small, shrivelled seeds, so that the useful yield of infected plants is very small. At the present levels of infection, however, it is thought that ...
Grain yields increased with sowing rate up to 640 seeds/m² in 1984 and up to 320 seeds/m² in 1985. Despite their different tillering habits, relative grain yield between the 3 cultivars could not be altered by sowing rate. On av., Siete Cerros yield...关键词:...
In the study, when seeds were at room temperature, SD6 was up-regulated to trigger seed germination. However, at low temperatures, SD6 was down-regulated, but ICE2 was up-regulated to keep the seed dormant. The researchers edited SD6 in three rice species and found that editing the gene...
