“…Young tissue would therefore be expected to be very sensitive to heavy metal inhibitors such as cyanide and carhon monoxide but as the lissue became less dependent on iron availability (due both to a decrea.sed respiratory rate and an increased iron supply) its sensitivity to chelating agents would decrease. As the leaves age the iron content increases steadily reaching a level as much as ten times Ihat present in young leaves (Glenister, 1944). There is some evidence that this may amount to an Iron toxicity which may exert an inhibitory effect on cellular respiralion (Warburg, 1949).…”

“…The level of iron is one of many factors that affects respiration in plant tissues (14). Iron functions in respiration as part of the prosthetic groups of several respiratory enzymes as well as being a constituent of the cytochromes (9).…”

Purple nutsedge(Cyperus rotundusL.) plants were analyzed for free reducing sugars, free glucose, free plus acid hydrolyzable fructose, phosphorus, and iron. The only sugars detected were sucrose, glucose, and fructose. Sucrose was the most concentrated sugar in the shoots with the greatest concentration in the younger leaves. Sucrose was also the most concentrated sugar in mature rhizomes. Glucose and fructose were the most concentrated sugars in the actively growing rhizomes and tubers. Phosphorus was concentrated in the actively growing leaves and rhizomes, while iron was most concentrated in older tissues including rachises with seedheads, mature shoots, tubers, and rhizomes.

“…Two other features, which have been said to accompany iron deficiency, were then investigated, viz. lower respiratory activity (Glenister, 1944) and accumulation of arginine (Holley and Cain, 1955).…”
