ADP-glucose pyrophosphorylase (AGP) was purified from tomato (Lycopersicon esculentum Mill.) fruit to apparent homogeneity. By sodium dodecyl sulfate-polyacrylamide gel electrophoresis the enzyme migrated as two close bands with molecular weights of 50,000 and 51,000. Two-dimensional polyacrylamide gel electrophoresis analysis of the purified enzyme, however, revealed at least five major protei...

The effects of different levels of nitrogen (100, 200, 300 and 400 mg/L) and potassium (125, 250 and 375 mg/L) on yield and leaf N and K concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. The highest fruit yield was obtained with 200 mg/L N. Higher levels of nitrogen decreased tomato yield. With increasing nitrogen concentra...

A severe disease of tomato was observed in 2010 in a greenhouse in the province of Lecce (Apulia, southern Italy). Plants showed interveinal yellowing and thickening of mature leaves and a bushy appearance of the new growth. Pale-yellow spots, which became sunken and necrotic, were scattered on the fruit surface. Leaf symptoms were reminiscent of those induced by Tomato chlorosis virus (ToCV) o...

In order to investigate the relationship between different traits with yield, an experiment was conducted on 16 tomato genotypes in randomized complete blocks design, with three replications. Twenty agronomical traits including plant height, stem diameter, number of shoots, plant weight, number of branches, number and dry weight of leaves, stems and roots, number of fruits per plant, fruit weig...

The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...

Climate change and essentiality of the food security have motived scientists to try innovative approaches, among which, crop growth models can help to predict crop yield. In order to simulate tomato (Solanum lycopersicum) growth, phenological characteristics of a short-life variety of tomato were assessed. Phenologic characteristics included leaf area index (LAI), specific leaf area (S...
