1) seed persistence
种子长久性
1.
In this study the relationships between seed size (mass) and seed persistence, dormant seeds number and total seeds number in soil seed bank, species abundance of vegetation and seedling, species distribution frequency of vegetation in three microhabitats (under shrub, the open area among shrub, trail) and their whole sand dune community in a Mediterranean coast sand dune were analyzed.
结果发现,在地中海沿岸沙丘生态系统,不同植物种子的大小是不一致的,有的相差可达千倍,但绝大多数植物的种子质量都不超过10mg,呈现近正态分布;植物种子的尺寸和大小具有显著的正相关关系;微生境影响种子大小与种子长久性的关系,在灌丛下、路径这两种微生境,种子大小与种子的长久性呈现显著的正向关系(p<0。
2) Transient soil seed bank

3.
The results indicated that the composition and density of both total soil seed bank and persistent soil seed bank all decreased with the increase of degradation degree,the soil seed density of heavily degraded and extremely degraded steppe dropped to only 46.
结果表明,随着草原退化程度的增加,不论是土壤总种子库还是持久土壤种子库,组成和密度均明显下降,重度和极度退化草原土壤总种子库密度下降至仅为轻度退化草原的46。
