在空气和N2中对6.1％和18．1％两个含水量的莴苣种子贮藏中生活力的丧失和染色体损伤情况进行了研究。在低含水量情况下，在N2中种子存活比在空气中好，但在高含水量情况下，在空气中比在N2中存活时间长，不管那种情况，贮藏中周围气体对存活种子的生活力及染色体损伤都影响不大，因而，种子贮藏在N2和空气中都同样表现为染色体畸变和生活力的丧失，但湿种子使生活力丧失的染色体畸变数目比干种子低、该文试图对种子在惰性区作中贮藏控制遗传退化问题进行初步探讨。
The loss of life and chromosomal damage in storage of lettuce seeds at 6.1% and 18.1% in air and N2 were studied. At low water content, seed survival is better in N2 than in air, but longer in air than in N2 at high water content, in which case the ambient gas in storage is less active than surviving seeds Vitality and chromosome damage have little effect, therefore, the storage of seeds in N2 and air also showed the loss of chromosomal aberrations and viability, but the loss of vitality of wet seeds so that the loss of viability of the number of chromosome aberrations than dry seeds, the text attempts Preliminary study on the problem of genetic control of seed storage in inert zone.
