现在在实验室的研究条件下,已能有效地把某些化学药品导入干燥的种子中,以加速或延缓种子萌发,从而能防止种子在运输、储藏和发芽期间品质的变劣。通常,种子处理是用化学药品的水溶液或干燥的粉状物进行的。但如果种子处理的目的是为了要把化学药品在种子开始萌动之前导入种子内部的话,那么无论是水溶液或干粉处理都是不能使人满意的。因为水溶液处理,往往在药品尚未扩散到种子内部的关键部位之前, Now under laboratory conditions, it has been possible to introduce certain chemicals into dried seeds efficiently to accelerate or retard the germination of the seeds, thereby preventing deterioration of the seeds during transport, storage and germination. In general, seed treatment is carried out with aqueous chemicals or dry powders. However, if the purpose of the seed treatment is to introduce the chemicals into the seeds before the seeds begin to germinate, then neither the aqueous solution nor the dry powder treatment is satisfactory. Because the aqueous solution, often before the drug has not spread to the key parts of the seed inside,
