摘要： 华北驼绒藜种子在超干燥(含水量4.2%～4.5%)室外温度条件下贮藏,与低温贮藏效果基本相同,能显著延长种子寿命。在超干燥贮藏过程中,种子的同工酶(超氧化物岐化酶、过氧化物酶、酯酶)系统的活性均明显高于对照,结果延缓了种子老化,提高贮藏寿命。

Abstract: Storing ultra dried Ceratoides arbrescens seed (MC 4.2%～4.5%) in an outdoor temperature or in a low indoor temperature achieves basically the same result-life of the seed is prolonged. During the storage period, the isozymes of the ultra dried C.arborescens seed show stronger kinetic properties than those of the control, thus deferring the ageing of the seed and enhancing its storage life.

Key words: Ceratoides arborescens, Seed, Storage, Isozyme
