Influences of Population Density of Plantago virginica on Its Morphological Characters of Underground and Aboveground Organs (English)
应用叶面分析仪、根系分析仪对北美车前(Plantago virginica)地上和地下部分形态进行了测定,考察北美车前种群密度对植株形态学参数的影响.结果表明,在生殖生长期间,北美车前地上部分和地下部分的形态参数均受到种群密度的制约,如地上部分的叶数、叶面积、叶周长、鲜重、花穗重、花数、花穗长;地下部分的根重、根长、根部表面积和根体积.不同直径的根的形态指标受种群密度影响的程度不同,其中以对中等直径等级的根长、根表面积、根体积和根部投影面积的制约作用最大.. (Chinese)
