各种乔灌木种子大多数是在秋季采种,翌年春季播种,需要经过一个冬天的贮存。很多树种子不是每年都结实,这就需要在种子丰收时大量采集而进行若干年的贮备,才能保证每年造林计划的完成。因此,研究怎样贮藏林木种子的问题有着重要的实践意义。一、林木种子贮藏的基本知识 1.林木种子的休眠与寿命:当种子成熟后随即转入休眠状态。所谓种子休眠是指有生活力的种子,由于某些内在因素或环境条件的影响而使种子一时不能发芽或发芽困难的状态,称为种子休眠。种子休眠有两种情况:一种是种子由于温度、水份和氧气以及光照等条件的不足而不能发芽,如满足其所需要条件就能很快发芽,这类种子的休眠称为被迫休眠。
Most of the various shrub and shrub seeds are planted in the autumn and planted the following spring, which requires a winter storage. Many tree seeds are not strong every year, which requires a large number of seed collection for a number of years of stocking in order to ensure the completion of the annual afforestation program. Therefore, studying how to store tree seeds has important practical significance. First, the basic knowledge of forest seed storage 1. Forest seed dormancy and life: When the seeds mature immediately into sleep. The so-called seed dormancy refers to the seed with vitality, due to some internal factors or environmental conditions so that the seeds can not germinate or germinate temporarily state, called the seed dormancy. Seed dormancy has two kinds of situations: one is the seeds can not germinate due to the lack of conditions such as temperature, moisture and oxygen and light, and the seeds can be quickly dormant if their conditions are met. The dormancy of such seeds is called dormancy .
