由于种子生活过程中经历着降低活力的不可逆变化,自身健壮度因此而受到影响,在生产实践中常表现出发芽率高而田间出苗率低的情况,至使影响产量。针对这样的情况,我们以逆境法分别对玉米新种和陈种进行处理,测其活力。同时,进行田间种植,观察生长发育和最后的产量情况,分析它们间的关系,为种子的收贮和生产服务。 1 室内的试验经过与结果在室内分别对1991年生产的新种郑单9号和 Due to the irreversible change of reducing vitality in the process of seed life, the self-robustness is thus affected. In the production practice, the high germination rate and the low emergence rate in the field often appear, which affects the yield. In response to such a situation, we adversarial approach to new varieties of corn and Chen species were processed to measure its vitality. At the same time, the field planting, observation of growth and development and the final yield situation, analyze the relationship between them, for seed storage and production services. A laboratory test passed and the results were indoors, respectively, on the 1991 new production of Zheng Dan No. 9 and
