| 摘 要： | 研究结果表明，水深决定了其生长区内竹叶眼子菜茎的长度，竹叶眼子菜茎叶比与水深有显著相关工：Ｙ＝０．００５１７Ｘ＋０．３１２６；竹叶眼子菜地上与地下部分生物量分配与水深没有相关性；沿着水深梯度，竹叶眼子菜的抽条数（无性繁殖）和花序数呈递减趋势。 |

| Abstract: | A field study was undertaken to investigate the growth and reproduction response of P. malaianus to water depth gradient. The results showed that the stem length of P. malaianus was decided by water depth where the plant grows. There is a significant relationship between stem:leave ratio of P. malaianus and water depth gradient. that the relationship between below-ground biomass of P. malaianus and water depth gradient was not found. With increasing of water depth, the number of plantlet and inflorescence gradually dwindles. |
