“…(Garg and Hemantaranjan, 1988). The greening effect of foliar applications of Fe on Kentucky bluegrass has been documented (Yust et al, 1984) and has been attributed to the requirement of Fe as a precursor in chlorophyll biosynthesis (Miller et al, 1982).…”

This study was conducted to determine the potential anti-senescence activity of certain chemicals by monitoring changes in gross. CO2 exchange with senescence of excised leaves of Kentucky bluegrass (Poa pratensis L.). One day following foliar applications of benzyladenine (BA), triadimefon, and propiconazole, with and without chelated Fe (8% Fe phosphate citrate), Kentucky bluegrass leaves were excised, floated on distilled water in petri dishes, and placed in a darkened growth chamber. Gross CO2 exchange rates (CER) were recorded 1, 4, 7, and 10 days after excision (DAE). Foliar applications of Fe, BA, triadimefon, or propiconazole applied alone induced an anti-senescence response. Combinations of Fe with the chemicals delayed excision-induced leaf senescence, but no significant increase in anti-senescence activity was obtained from the Fe and chemical combinations as compared to the materials applied alone. Chemical names used: N-(phenylmethyl)-1H-purin-6-amine (benzyladenine, BA); 1-(4-Chlorophenoxy)-3,3-dimethyl-1(1H-1,2,4-triazol-1yl)-2-butanone (triadimefon);1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole (propiconazole).

“…The stimulation in the enzyme activity is almost double in relation to their respective controls, but the accumulation in P content is more pronounced at excess P with excess Co might be due to higher supply of both. As has been reported by Miller et al [29] most probably in Fe deficiency the condensation of glycine and succinyl CoA decreased to form delta amino laevulinic acid (ALA), a precursor of porphyrin. This in turn might disturb the carbohydrate metabolism which gets support from low Hill reaction activity in excess Co, more significant being in adequate P. The decrease in growth and biomass and low concentration of chlorophyll a and b of tomato ( Fig.…”

Tomato (Lycopersicon esculentum) cv Ali vikas was grown at normal [without added cobalt (Co)] and excess Co (0.5 mM) in refined sand to see the effects of excess Co (0.5 mM) and its amelioration by high phosphorus (P). Apart from this, effect of high P (3 mM) and its withdrawal for 45 days (after 56 days of excess P supply) have also been observed on tomato physiology. The visible symptoms of excess Co appeared first in high P but were more pronounced in adequate P. In tomato, excess Co depressed the biomass, concentration of iron (Fe), chlorophyll a and b, Hill reaction activity, and activity of catalase and increased that of peroxidase, acid phosphatase, and ribonuclease along with accumulation of Co, more significantly with adequate P. High P partially ameliorated the effects of excess Co in tomato with almost no toxic effects of its own. Complete withdrawal of high P (for 14 days) improved the biomass, content of chlorophyll a and b, and Fe, and activity of catalase and reduced

The formation of delta‐Aminolevulinate a precursor of chlorophyll, in barley and the role of iron

Abstract: Chlorophyll formation in higher plants is light dependent. Light directly affects the formation of 6-aminolevulinic acid (ALA) and the conversion of protochlorophyll to chlorophyll.
