中文摘要：

本文提出了＂种子地理学＂的新概念,给出了定义,并归纳了种子地理学的研究内容,阐述了种子地理学的科学问题和主要任务.种子地理学是在植物地理学、植物群落学和种子生态学等学科基础上发展起来的一门新兴的交叉学科,研究种子从宏观至微观各种生物学性状的地理变异规律及其与环境因子的关系,以及种子性状的形成、发展和变化趋势.其主要内容可概括为：1）种子质量的地理学;2）种子化学成分的地理学;3）种子形态学性状的地理学;4）种子细胞学性状的地理学;5）种子生理学性状的地理学;6）种子遗传学性状的地理学;7）花和果实的地理学.开展种子地理学研究,能更好地理解植物种子对环境的长期适应进化规律.

英文摘要：

In this paper,a new concept ＇seed geography＇ was provided,and its definition,research contents,and scientific issues were put forward.Seed geography is a newly developed interdisciplinary science from plant geography,seed ecology,and phytosociology,which studies the geographic variation patterns of seed biological traits as well as their relationships with environmental factors from macroscopic to microscopic,and the seed formation,development,and change trends.The main research contents would include geography of seed mass,geography of seed chemical components,geography of seed morphology,geography of seed cell biological characteristics,geography of seed physiological characteristics,geography of seed genetic characteristics,and geography of flower and fruit.To explore the scientific issues in seed geography would help us to better understand the long-term adaptation and evolution of seed characteristics to natural environments.
