“…Olsen (8) 30, 1954. in which the iron and phosphorus contents of green and chlorotic leaves were given (6,13,14,16,17), it appeared that the same trend in the phosphorus-iron ratio occurred irrespective of the cause of chlorosis. Similarly, symptoms of phosphorus deficiency (3), or phosphorus toxicity (12) were in accordance with the expected phosphortus-iron ratio in each case.…”

“…However, the investigator soon faces the problem of the comparative iron status of green and chlorotic leaves. Some investigators have found less iron in chlorotic than in green leaves and have demonstrated a good correlation between iron and chlorophyll contents (8,15,18). But also, it has been found that chlorotic leaves may contain as much or more iron than comparable green leaves (7,11,19).…”

“…The full-nutrient solution contained the following supplemental metals in p.p.m. : A, none; B, 75 Mn; C, 75 Zn; D, 2.5 Cu; E, 5 Cu; F, 10 Cu; G, 10 Cu; H, none; I, 0.25 Cu; J, 3 Zn; and second vermiiculite experimiient, where Fe was a variable, no difference in growth, intensity of chlorosis, or reduction in metal toxicity to roots was associated with the rate of Fe-tartrate supplied. The use of chelated Fe, however, prevented the development of chlorosis but did not overcolmle the suppressive effect of Cu on growth.…”

The recent widespread increase in iron chlorosis on acid, sandy soils in Florida has led to studies of the underlying causes. The leaves on affected trees are deficient in iron (10). Field (3,5).Little is known about the fundamentals of heavy-metal nutrition of citrus. There is actually little information on the relative toxicities, antagonistic reactions, or the nature and extent of the accumulation of heavy metals in roots of any plant. Much additional research is needed to elucidate the processes of their absorption and accumulation. The present studies were made with the hope that some information on these aspects of nutrition could be gained and it is felt that the results presented will contribute toward this end. Materials and methodsThe plants tested were young citrus seedlings grown in seedbeds of vermiculite as described elsewhere (9). Valencia orange seedlings were used mostly; however, some Sunki mandarin seedlings were included in one experiment. The seedlings were one to two months old when used and the experiments were continued two or three months, which gave sufficient time for a widely differential growth response.Two systems of culture were used. The first involved use of clay pots filled with vermiculite and placed in glazed pottery vessels which permitted sub-irrigation with the desired nutrient solution. The solution was flushed through the pot twice weekly and adjusted frequently to keep the pH near 4 and to maintain the liquid level. Fresh solutions were applied about every two weeks. The second system was a solution culture in one-quart glass jars that had been painted successively on the outside with asphalt and 371 www.plantphysiol.org on May 9, 2018 -Published by Downloaded from
