植物顽拗性种子研究进展

Advances on Recalcitrant Seeds of Plants

摘要:

对植物顽拗性种子的概念、物种分类、形态、分布及一些生理生态特征进行了综述,分析了顽拗性种子脱水敏感性的原因和对环境的生态适应性,探讨其可能的进化地位和贮存技术。同时,对顽拗性种子研究的发展趋势和应用前景进行了展望,即加强生境调查,更新顽拗性种子植物数据库,从形态学、生理生态学和分子生物学分析种子顽拗性本质。

Abstract:

The concepts, classification, morphology, distribution and physiological ecology characters in recalcitrant seeds were reviewed, the reasons of desiccation sensitivity and the adaptability to ecological environment of recalcitrant seeds were analyzed, its possible evolution status and effective storage technology were discussed. The development tendency and application prospects for studying on recalcitrant seeds were proposed. It was suggested that the further researches should be focus on these issues, such as habitat investigation, establishment and update of plant database in recalcitrant seeds, and analysis of the nature of recalcitrant seed based on morphological, physiological ecology and molecular biology.
