Active extrusion of protons into deionized water by roots of intact maize plants.
The investigations were focussed on the question as to whether roots of intact maize plants (Zea mays L. cv Blizzard) release protons into deionized H(2)O. Plants in the six to seven leaf stage depressed the pH of deionized H(2)O from 6 to about 4.8 during an experimental period of 4 hours. Only one-third of the protons released could be ascribed to the solvation of CO(2) in H(2)O. The main cou...
متن کاملAcidification of Deionized Water by Roots of Intact Rice Seedlings
This investigation was designed to examine whether or not deionized water could be acidified by roots of intact rice seedlings. Roots of intact rice seedlings caused significant acidification of the deionized water in which they were immersed and this acidification could be repeated after replacement of acidified water with fresh deionized water. The addition of K, Na, and Mg* to the deionized ...

A Method for Characterizing the Relation between Nutrient Concentration and Flux into Roots of Intact Plants.
A method based on the rate of depletion of a nutrient from solution was developed to characterize nutrient flux of plant roots. Nutrient concentration of the solution was measured at a series of time intervals to describe the complete depletion curve. An integrated rate equation, based on a Michaelis-Menten model, was developed and fit to the data of the depletion curve using a least-square pro...
