| 摘 要： | 种子际(Spermosphere)是植物微生态系统的重要组成部分,在种子萌发的短暂时间内富于微生物群落的形成和功能的瞬时演替特性.萌发种子分泌物的瞬时演替释放对种子际固有和接佑种微生物的群落多样性、增殖和活性具有调控作用;种子际微生物的趋化性对于微生物的定殖和对病原菌的拮抗能力以及生物防治效果有重要影响;在种子际微生态学研究中,应注意把握种子际分泌物释放的短暂时间框架和测试条件的统一性;将微生物传统培养方法和非培养方法相结合,该领域的深入研究将为根际微生物的起源以及有益微生物接种剂的合理应用提出新的见解和科学依据. |
| 关 键 词： | 植物种子际 种子分泌物 微生物群落 瞬时演替 |

| Abstract: | The spermosphere as an important habitat in plant micro-ecosystem is rich in temporal succession of microbial communities form and function. The indigeous and inoculated microbial community diversity, proliferation and activity could be regulated by the temporal succession and exudation of germinating seed exudates. The microbial chemotaxis in spermosphere is essential for their colonization , antagonistic activity to pathogens and bio-control of plant diseases. It shoud be assured that all the determination carried out are within the ephemeral time frame of germinating seed exudation and microbial activity with the unique experimental conditions in studies on the spermosphere micro-ecology. And some new insights would be proposed for the origin of microbes in rhizosphere and the reasonable application of benificial microbial inoculants in further investigation with the culture-independent as well as culture-dependent approaches in this area. |
| Keywords: | Plant spermosphere Seed exudates Microbial community Temporal succession |
