种子在贮藏期间,照样不断地进行生理活动和生物化学变化。种子在贮藏期间新陈代谢的主要标志就是呼吸作用。种子贮藏的好与坏,除了种子本身条件外,更主要的是看贮藏时的环境条件对种子呼吸的影响,而影响呼吸作用的因素主要有三个: 1、种子本身含水量的大小。一般是潮湿的种子呼吸作用强烈,干燥种子呼吸作用微弱。含水11％-13％的种子,呼吸作用不明显;可是,当种子含水超过15％时,呼吸作用就会骤然增强,因为种子含有15％以下的束缚水,
During storage, the seeds continue to undergo physiological activities and biochemical changes. The main indicator of metabolism during storage is respiration. Seed storage is good and bad, in addition to the seed itself conditions, the more important is to look at the storage of environmental conditions on the impact of seed respiration, and affect the respiration of the three main factors: 1, the size of the seed itself water content. Breathing is generally wet seeds, respiration of dry seeds weak. Breathing is not obvious with 11% -13% watery seeds; however, when the seed moisture content exceeds 15%, the respiration increases sharply as the seeds contain less than 15% bound water,
