祁连山地区蕨麻功能性状和生长策略对土壤因子的响应
Morphological responses of Potentilla anserina to soil factors across different habitats of the Qilian Mountains
摘要
Abstract
Potentilla anserina is a typical pioneer clonal plant.To investigate the adaptive strategy of P.anserina to environmental conditions,four representative habitats in the Qilian Mountains were selected,including floodplain,shrub-grassland,alpine meadow,and marshy meadow.Morphological indicators of P.anserina and associated soil nutrients and physicochemical properties were determined and analyzed using correlation analysis.The phenotypic plasticity coefficient of P.anserina was highest in the floodplain habitat(33.0)and lowest in the marshy meadow habitat(6.43).The development of P.anserina was influenced by habitat soil physicochemical factors and exhibited good phenotypic plasticity.Soil moisture content was significantly(P<0.05)negatively correlated with leaf weight,and extremely significantly(P<0.01)negatively correlated with stem weight,root weight,and total weight of P.anserina.Soil pH and soil bulk density were highly significantly(P<0.01)positively correlated with root weight,stem weight,and total weight,and significantly(P<0.05)positively correlated with leaf weight.Soil nutrients were significantly(P<0.05)negatively correlated with the vertical expansion index,leaf weight,root weight,and total weight of P.anserina.These results demonstrate the organ allocation strategy and expansion capacity of P.anserina in response to the environment in the Qilian Mountains and provide a theoretical basis for using clonal plants like P.anserina for the ecological restoration of alpine meadows.关键词
