种子传播将母株生殖周期的末端与它们后代种群的建立连结了起来,广泛认为,其对植被结构具有深刻的影响。种子传播的整个过程称为种子传播循环。研究表明,杂草种子传播的因子多种多样,包括仅依赖自身来完成的主动传播,以及依赖风、水、动物、人类等外界媒介的被动传播。其中,人类传播杂草种子是影响最广泛的一种,对现代植物的分布格局产生了深刻的影响。杂草种子的传播,对杂草种子库的数量和空间动态影响很大。研究种子传播的主要方法有荧光染料标记法、放射性同位素标记法、稳定同位素分析、分子遗传标记等。结合近几年国内外的研究进展,作者就杂草种子传播对种子库数量和空间动态影响的精确直接研究、杂草种子传播的过程及传播后的命运、杂草种子适应传播的机理、生态控草措施研究、外来杂草入侵蔓延与其种子传播的关系等方面提出了展望。
Seed propagation Linking the ends of the reproductive cycle of the mother plant with the establishment of their offspring, it is widely accepted that they have a profound effect on vegetation structure. The whole process of seed propagation is called the seed propagation cycle. Research shows that weed seeds have a variety of factors that can be transmitted, including the active transmission that depends on themselves and the passive transmission of external media such as wind, water, animals and humans. Among them, weeds spread weeds is the most widely affected species, the distribution pattern of modern plants had a profound impact. The spread of weed seeds has a great influence on the quantity and spatial dynamics of weed seed banks. The main methods of studying seed propagation include fluorescent dye labeling, radioisotope labeling, stable isotope analysis and molecular genetic markers. Based on the research progress in recent years at home and abroad, the authors studied the precise and direct study on the impact of weed seed transmission on the number and spatial dynamics of seed bank, the process of weed seed transmission and the fate of its spread, the mechanism of weed seed adaptation propagation, Control measures research, the spread of invasive weeds and their relationship with the spread of seeds and other aspects of the prospects.
