Abstract:Changes in composition of five different ions in bush beans (Phaseolus vulgaris L. var. Improved Tendergreen) exposed for 40 hours to different experimental conditions were studied by means of emission spectrography. At 24°c newly absorbed Mg and Na tended to remain in roots; P and K tended to be somewhat equally distributed between root and shoot, and Ca tended to be transported to shoots. At 4°C absorbed Na was transported to shoots. The low temperature (cold shock) also caused a large net loss of K from pla… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
