喜旱莲子草入侵群落土壤对植物生长的影响OA北大核心CSCDCSTPCD
Effects of soil under Alternanthera philoxeroides-invaded plant community on the growth of plants
分别以受喜旱莲子草(Alternanthera philoxeroides)入侵和未受喜旱莲子草入侵的当地植物群落土壤为生长基质,比较不同基质上入侵植物喜旱莲子草和同属的土著植物莲子草(A.sessilis)的生长指标,探讨喜旱莲子草入侵群落土壤对喜旱莲子草及莲子草生长的影响机制.结果表明,喜旱莲子草入侵群落土壤抑制了莲子草的生长,显著降低了根生物量、茎生物量和总生物;改变了形态特征,显著降低了分枝数量、茎长度、根长、根体积;减少了对根的生物量分…查看全部>>
The soils under native plant community with and without Alternanthera philoxerodies invasion were taken as the growth medium to study whether plant-soil feedback contributes to the invasion success of A. philoxeroides. The soil under A. philoxeroides-irrvaded community inhibited the growth of native A. sessilis significantly, which manifested in the decreases of root biomass, stem biomass, total biomass, relative growth rate, and net assimilation rate, and i…查看全部>>
