The effect of mineral nutrient deficiencies on the structure of the leaf cells of tomato, spinach, and maize

Abstract: Observations were made by electron microscopy of the leaf cells of normal (full nutrient) tomato, spinach, and maize plants and of plants grown deficient in each of the known essential macro- and micronutrients except chlorine. In the case of spinach, observations were also made by phase contrast and fluorescence microscopy. A feature of this study was the large variation found in the shape, size, and appearance of chloroplast sections from both full-nutrient and mineral deficient plants. A representative rang… Show more

“…The decrease in the size and number of starch grains is consistent with the reports by others (15,20,22). Furthermore, it is again our unique plant materials that provide a further documentation for such a relationship.…”

“…The observed reduction in starch content under Zn-deficient conditions is consistent with reports on other plant species (15,20,22). Moreover, a correlation between the relative reduction in starch content in Saginaw and Sanilac under low Zn, and their genotypic difference in sensitivity to low Zn, suggests that a marked decrease in starch content may be associated with Zn deficiency.…”

“…There was no indication from the present work that Cu deficiency reduced the amount ofthylakoid material per chloroplast and there was no effect on chloroplast ultrastructure except in very young, severely deficient leaves. Vesk et al (20) similarly found no evidence of loss of thylakoid material with Cu deficiency. Furthermore, we found that the thylakoid protein content (per Chl) of deficient chloroplasts was nearly double that of the control; the protein/Chl ratio was 25 and 11 in the deficient and control chloroplasts, respectively.…”

“…The chlorosis has been characterized histologically as the discontinuous distribution ofChl within the chloroplasts (9). Vesk et al (20) found no ultrastructural alteration between the Cu-deficient and control chloroplasts. Baszynski et al (4) noted some depletion of chloroplast membranes with Cu deficiency.…”

“…First, N starvation induces a decrease in photosynthesis which often occurs before a measurable decline in chlorophyll content (Bouma 1970). Sec-ond, these effects are reversible and activity is restored when the plants are rewatered with a normal nutrient solution (Vesk et al 1965;Natr 1970Natr ,1972; this reversibility is more apparent when activity is expressed per gram of chlorophyll (Baszynski et al 1975 …”
