Abstract
SOME years ago I demonstrated1 that excised barley leaves from phosphorus-deficient plants showed considerably increased respiration intensities if their cut ends were immersed in neutral sodium phosphate solution instead of water. Feeding similar leaves with sucrose solution also increased the respirationrates ; but the increase was much smaller than when phosphorus was administered. The sucrose effect was less apparent when phosphorus deficiency was more acute. Still higher rates of respiration were obtained if the phosphorus-starved leaves were supplied with both sucrose and phosphate together.
