| 摘 要： | 三峡水库实验性蓄水后,水库消落带内出现了罕见的苍耳(Xanthium sibiricum)带.通过对不同水淹处理后苍耳种子萌发特性的测定,研究水淹对苍耳种子萌发的影响.结果表明,苍耳种子具有较强的耐淹能力,即使受近8个月原位水淹胁迫,90％以上的苍耳种子依然保持有生活力.在25℃下,原位水淹的苍耳种子去总苞后的发芽率显...

| Abstract: | Common cocklebur (Xanthium sibiricum) was widely distributed in the water-level fluctuation zone of the Three Gorges Reservoir after its impoundment to 156 m in elevation. Flooding maybe accelerated the germination of common cocklebur and it was likely to be the explanation of the phenomena. The aim of present paper was to determine the influence of water submergence on the germination of common cocklebur. The result showed that more than ninety percent of seeds even submerged in situ for even eight months ... |
