中文摘要：

低浓度的铝胁迫处理对车前（Plantago asiatica L.）的开花物候没有显著影响，而高浓度处理下，不仅车前的高峰期当日平均穗长及其花数、终花当日平均穗数及其穗长显著下降，且始花目推迟，花期持续时间缩短；还导致车前平均抽穗数、穗长和开花数显著减少。但对可结实车前的种子千粒重无显著影响。

英文摘要：

There were no significant effects on the flowering phenology of Plantago asiatica under low con- centration of aluminum stress treating. However, we found that the average spike length and their flower numbers at the onset day, the average of spikes and their length at the end-set day decreased significantly under the high concentration of aluminum stress treating. At the same time, the beginning flower day were delayed and flowering duration were shortened. Furthermore, aluminum stress also caused that the average number of spikes, the spike length and flowers decreased significantly. Finally, it was not significantly ef- fect on the weight of seed.
