“…Probably the largest and most consistent increases in the ascorbic acid content of plants have been caused by increases in light intensity, a phenomenon reported by Aberg (Z), Hammer, Lyon, and Hamner ( 6 ) , Bernstein (2), Hamner and Parks (8), and Somers, Kelly, and Hamner (22).

It is well recognized that factors affecting the vitamin content of plants usually cause composition changes of considerable nutritional importance. Most previous investigations of these effects have considered a single factor rather than studying several factors simultaneously.Harmer and Sherman (9) and Hester (20) have indicated that low ascorbic acid content of certain plants is associated with a deficiency o r low availability of manganese in the soil. I n these instances, applications of manganese increased the ascorbic acid content of plants. Gum, Brown, and Burrell ( 4 ) , Lyon and Beeson (11,22), and Lyon, Beeson, and Ellis (?3), report either no effect, or slight but inconclusive effects, on the ascorbic acid content of certain plants when minor element application was made in amounts ranging from deficient t o toxic concentrations.Probably the largest and most consistent increases in the ascorbic acid content of plants have been caused by increases in light intensity, a phenomenon reported by Aberg (Z), Hammer, Lyon, and Hamner ( 6 ) , Bernstein (2), Hamner and Parks (8), and Somers, Kelly, and Hamner (22). The influence of fertilizers on the ascorbic acid content of turnip greens has been studied by workers of the Southern Cooperative Group at several locations in the South. Reports on these studies have been made by Reder, Ascham, and Eheart ( l a ) , Reder et al. (15), and Sheets et al. (28). Although the fertilizer treatments produced no consistent effects, increases in the ascorbic acid content of the greens occurred at locations having high light intensities prior to harvest.Work by Bernstein, Hamner, and Parks ( 2 ) and Hamner and Maynard (7) showed that increases in the carotene content of turnip greens and tomatoes respectively were obtained with increased light intensity. Gustaveson (5) found that increasing light intensity caused proportional increases in the thiamine content of tomatoes, potatoes, beans, peas, and New Zealand spinach; and consistent but less pronounced increases in the riboflavin content of these vegetables. Excellent literature reviews on the effect of environment on the chemical composition of plants have been prepared by Somers and Beeson (20) and Richardson et al. (16).Recognizing the limitations of single-factor experiments for obtaining information of this type, an experiment was initiated in 1950 at Blacksburg, Virginia, in which the effect of crops, soil pH, light intensity, and minor elements, and their interactions, on the nutritive value and yieId of turnip greens, were studied simultaneously.

Seedlings of Setaria verticillata were grown in nutrient solutions containing platinum applied as K 2 [PtCI 4 ]. After two weeks growth, at a platinum concentration of 0.5 µg cm -3 , the length of the longest roots had increased, on the average, 65% more than the controls. Phytotoxicity was evident at a Pt concentration of 2.5 µg cm -3 . Analysis by atomic absorption spectroscopy (AAS) showed that platinum had been taken up by the roots at both concentration levels, and at the higher level, Pt was also detected in the shoots. Further analyses, carried out by inductively coupled plasma atomic emission spectroscopy (ICP AES), showed that there were higher levels of calcium, copper, iron, manganese and zinc in the platinum treated plants in comparison to the controls. The growth of this species on flotation tailings was very poor, largely because of the lack of essential macronutrients. It is concluded that the potential use of this species, either for the colonisation of tailings, or for the removal of any low levels of Pt remaining in the tailings after processing, is not a viable proposition.

The heavy metals, copper, zinc, manganese, iron and molybdenum are now accepted as essential plant nutrients, and their probable significance as key factors in enzyme systems has suggested that they may directly or indirectly influcncp vitamin synthesis.The development of technical reliability in the determination of ascorbic aeid in plant material, Lugg (1942) and in the location of micronutrient and potash deficiency by the response of herbage legumes in controlled soil cultures, Ferrns and Trumble (1943), made possible the work herein described.The literature concerning variation of ascorbic acid content with applications of mieronutrients has been reviewed by Maynard and Beeson (1943), who found it too contradictory to give any definite conclusion. They quoted two instances of increase in ascorbic acid with zinc in oranges, Roy and Bahrt (1940) and Cowart (1941), but cited evidence brought forward by Lyon, Beoson and Ellis (1943) which showed that marked increases in the growth of tomatoes following the addition of zinc were unaccompanied by any change in the concentration of ascorbic acid.Hester and Kohman (1940) and Rugawara (1941) secured an increase in ascorbic acid with the application of potash to tomatoes and potatoes respectively. Hamner, Lyon and Hamner (1942) on the other liand, found no substantial effect of potash on tomatoes when other elements were kept sufficiently high.Rudra (1944) has reported that "manganese has a specific role in the synthesis of ascorbic acid by plants and animals", and Hester (1941) has found a lower level in tomato jjUints untreated with manganese than those to which manganese was added. On the other hand Lyon aud and Lyon, Beeson and Ellia (1943), obtained no change in the concentration of ascorbic acid with the addition of this element.There is considerable evidence to indicate that climatic factors affect the vitamin content of plants grown for food; in particular the dominant rolo of light in the ascorbic acid content of plants has been recognized, Maynard and Be«son (1943). Work by B«id (1942) indicated that both high light intensity and long days were conducive to higher ascorbic acid values in cow peas; a sufficient supply of available ma,ior nutrients, with special reference to nitrogen, was stated to favour a higher content of ascorbic acid, provided light was available for the active synthesis of carbohydrate.While it is well known that the ascorbic aeid content of plants varies with the locality, it has been generally impossible to ascertain the specific factors involved iu the environmental complex. In all cases there has been insufficient <'ontrol of the individual variables concerned. No work appears to have been carried out on the possible interactions of micronutrients and climatic factors as affecting the ascorbic acid content.Recently Hamner (1945), in a further review, concluded that variations in the ascorbic acid content of plants are so influenced by varietal differences and by climatic conditions that soil factors and tho application of ferti...
