Xylem sap circulates under either positive or negative hydraulic pressure in plants. Negative hydraulic pressure (i.e., tension) is the most common situation when transpiration is high, and several devices have been developed to quantify it accuratel

Nitrate and potassium uptake are strongly correlated in deciduous trees from bud break to leaf fall. A conceptual model for potassium cycling is proposed to explain this result. We have studied the correlation between nitrate and potassium uptake in

We studied the short-term (i.e., a few days) effect of a sudden increase in CO2 uptake by shoots on nutrient (NO3-, P ion, K+, Ca2+ and Mg2+) uptake by roots during vegetative growth of young walnut (Juglans nigra x J. major L.) trees. The increase i
