Staniaszek M., Szczechura W., Marczewski W. (2014): Identification of a new molecular marker C2-25 linked to the Fusarium oxysporum f.sp. radicis-lycopersici resistance Frl gene in tomato. Czech J. Genet. Plant Breed., 50: 285–287. Fusarium oxysporum Schlecht. f.sp. radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in...

The aim of this study was to investigate the effect of different types of tomato processing on contents of lycopene, beta-carotene, and alpha-tocopherol. Samples of tomato sauce, tomato soup, baked tomato slices, and tomato juice were taken at different times of heating, respectively, after each step of production. HPLC was used to analyze contents of carotenoids and vitamin E. Due to the loss ...

Tomato spotted wilt virus (TSWV) is one of the most destructive viral diseases that threaten worldwide tomato (Solanuum lycopersicum L. syn Lycopersicon esculentum Mill.) production. Use of host resistance appears to be the best way to control the disease. Marker assisted selection (MAS) has become very important and useful in the selection of TSWV resistance genes. The objective of this resear...

Millet, milo, soybean, crotalaria, and Norman pigeon pea were used in conjunction with clean fallow and a nematicide (fensulfothion) for managing nematode populations in the production of tomato transplants (Lycopersicon esculentum Mill.). Glean fallow was the most effective treatment in suppressing nematode numbers. After 2 years in tomato, root-knot nematodes increased in numbers to damaging ...

his study aimed to investigate factors affecting the revenue share of Iranian tomato paste exporting companies. Flexible estimation method was used on a two-dimensional panel data set including 224 observations from 14 tomato paste manufacturing and exporting companies and 16 importing countries during 2005-12. Results showed that value added per employee in manufacturing or exporting companies...

In this paper the nature of root-to-shoot signals in plants growing in drying soil is considered in the context of their commercial exploitation in tomato (Lycopersicon esculentum L.) and other crops. Recent findings are presented on the effects of partial root drying (PRD) in the production of a glasshouse tomato crop. These findings show how an understanding of both root-to-shoot signalling m...

abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...
