Application of root zone feeding for evaluation of ion uptake and efflux in soybean genotypes



Application of root zone feeding for evaluation of ion uptake and efflux in soybean genotypes



Plant and Soil 72(2/3): 239-243



In three intact, differentially salt-sensitive cultivars, about 70% of the 22Na+ taken up in saline hydroculture conditions by the labelled apical 8 cm of the seminal root was released during transport through the proximal root tissue into the ambient inactive nutrient solution. When the retention capacity in the uptake zone was saturated, 36Cl- was partly retained along the pathway through the root, especially in Lee.
