| 摘 要： | 种子萌发是植物生命的开端,此过程需要多种贮藏物质的动员来提供营养及能量,贮藏物质对种子萌发至关重要。本文概述了种子萌发所需主要贮藏物质(糖类、蛋白质、脂肪、磷)在种子萌发中的作用、动员情况和代谢变化规律,并与经劣变(老化)后的种子进行比较,从贮藏物质角度解析劣变对种子萌发和活力的影响,并对该领域未来的研究方向进行了展望。相关结果对于从多角度全面解析和研究种子萌发和劣变机制具有非常重要的理论指导意义。

| Abstract: | Seed germination is the beginning of plant life,and this process requires the mobilization of various storage materials to provide nutrients and energy.Therefore,storage materials are essential for seed germination.In this paper,the effects of main storage substances(e.g.sugar,protein,fat and phosphorus)on seed germination,mobilization and metabolic changes during seed germination were surveyed.Meanwhile,compared with the seeds after deterioration(aging),the effects of deterioration on seed germination and vigor were analyzed based on the changes of storage materials.Also,the future research direction in this field was prospected.These results are of great theoretical significance for comprehensively analyzing and studying the mechanism of seed germination and deterioration from multiple perspectives. |
