| 摘 要： | 本文调查了北美车前分主然害现状，对其生物生态学特征进行了研究，旨在掌握其生长发育过程中的薄弱环节，为综合防除该害草提供依据。结果表明，北美车前在华东地区已有较广分布；在金华地区，北美车前是一种过渡性的先锋群落性物种；具自花传粉及风媒传粉两种授粉机制，气候条件，种群密度，人为干扰影响着风媒传粉的比例；种群的分布具明显的伴人特征；光合作用特征为光补偿点高，光合速率较低。

| Abstract: | Plantago virginica L.,a weed originating from North America,was introduced into China about 1980's.Its characteristics research of biology and ecology in this paper shows:1.P.virginica L.has been widely distributed in east China; 2. its population is a transient one in Jinhua area,Zhejiang province;3.it has two types of flowers:anemophilous flower and cleistogamo us flower,and the later is the main one. climate condition,Plantago virginica L.population density and man-made interference have influences on the percentage of anemophilous flower;4.high ligh compensation point and lower photosynthetic rate are its photosynthetic characteristics. |

| Keywords: | Plantago virginica L. biology and ecology breeding system. |
