Transpiration stream & ascension of calcium.
Since Cline's report (5) of a very slow equilibration in the leaves of tritiated water absorbed by the roots of bean plants, no resolution has been made between his expressed alternative views that this was due A, to failure of tissue water to exchange with the incoming tritium-labeled water, or B, to a large isotope effect. During the preparation of the present manuscript Vartapetyan and Kursa...
متن کاملThe Transpiration Stream and Upward Translocation of Mineral Ions
Ca and P were supplied simultaneously to young Phaseolus vulgaris L. seedlings grown in solution. After short periods of uptake, the Ca/P ratios in opposite leaves and opposite leaflets were very similar. This relationship also held when Ca and Cs were paired. Ca/P ratios in lateral halves of the same leaf were in good agreement, also. However, the basal halves of leaves always had higher Ca/P ...

متن کاملRoot-synthesized cytokinin in Arabidopsis is distributed in the shoot by the transpiration stream.
To clarify how root-synthesized cytokinins (CKs) are transported to young shoot organs, CK distribution patterns were analysed in free-CK-responsive ARR5::GUS transformants of Arabidopsis thaliana (L.) Heynh. together with free plus bound CKs using specific CK monoclonal antibodies. Plants were subjected to two different growth conditions, completely protected from any air movement, or exposed ...
