优良种子是幼苗生长良好的基础。在贮藏、交换、调运种子的过程中,都需要及时了解种子的发芽力。研究种子的活力,对于农业机械化栽培作业具有特别重要的作用。例如,在美国,用机械播种莴苣时,为了节省种子用量和疏苗的劳动力,每穴只播一粒种子,因此,必须确保每粒种子均能发芽,幼苗生长速度一致,才能一次进行收获。常规发芽试验太费时间,同时对于休眠种子无效。因此,有必要探索快速鉴定种子发芽力的方法。目前常用的方法有以下几种: 去皮、分离胚、切割子叶、半粒发芽法
Good seed is a good seedling growth basis. In the process of storing, exchanging and transferring seeds, we need to know the germination power of the seeds in time. Studying the vitality of seeds has a particularly important role for agricultural mechanized cultivation. For example, in the United States, when mechanically sowing lettuce, only one seed per hole is needed to save seed and sparsely populated labor. Therefore, it is important to ensure that each seed germinates and the seedling grows at the same rate to harvest it once. Conventional germination tests are too time consuming and are not effective on dormant seeds. Therefore, it is necessary to explore the rapid identification of seed germination methods. Currently used in the following ways: peeled, embryo separation, cutting cotyledons, half-sprout method
