Sap Flow Dynamics of Quercus pubescens and its Hemiparasite Loranthus europaeus

Popis výsledku v původním jazyce

Measurements of sap flow density (SFd) in different organs of oak tree (Quercus pubescens) infested by Loranthus europaeus were performed at the Pouzdrany steppe (Czech Republic). Sap flow was measured in a deep root, two shallow roots, two sides of stem, four oak branches, three oak branches infested by mistletoe and two male mistletoe plants using single- and three-point heat field deformation (HFD) sensors. Evaluated period consisted of three days with high reference evapotranspiration (PET) followedby one day with rain events and two following days without rain. The Loranthus europaeus participated to transpiration process with large amount of water from its storage tissues. This hemiparasitic plant more drove afternoon and night flows in host tree independently to drought stress. Deep roots substantially participate to daily water flow in tree especially during drought. Reverse flow in shallow roots was observed under soil drought conditions and low PET as deep root supplied wate
