Tomato (Solanum lycopersicum L.) is susceptible to many diseases including bacterial speck caused by Pseudomonas syringae pv. tomato. Bacterial speck disease is a serious problem worldwide in tomato production areas where moist conditions and cool temperatures occur. To enhance breeding of speck resistant fresh-market tomato cultivars we identified a race 0 field isolate, NC-C3, of P. s. pv. to...
UNLABELLED The characteristics of tomato pericarp are closely associated with peelabililty, an important quality attribute of processing tomatoes. Different types of tissue exist in the pericarp of tomato. The outermost region of the pericarp, the red layer, is removed with the skin during peeling. This study investigated the morphological features and tissue properties of red layer and pericar...
In addition to the ethylene formed at the onset of tomato fruit ripening, three peaks of ethylene are produced during earlier periods of in vitro development of tomato flower to fruit. This is the first report characterizing ethylene production during early development of tomato fruit. Previous reports from this laboratory showed that VFNT Cherry tomato calyces are transformed into fruit tissue...
Companion cropping with potato onions (Allium cepa var. agrogatum Don.) can enhance the disease resistance of tomato plants (Solanum lycopersicum) to Verticillium dahliae infection by increasing the expressions of genes related to disease resistance. However, it is not clear how tomato plants physiologically respond to V. dahliae infection and what roles sulfur plays in the disease-resistance. ...
Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercr...
Phenotypic diversity within cultivated tomato (Solanum lycopersicum) is particularly evident for fruit shape and size. Four genes that control tomato fruit shape have been cloned. SUN and OVATE control elongated shape whereas FASCIATED (FAS) and LOCULE NUMBER (LC) control fruit locule number and flat shape. We investigated the distribution of the fruit shape alleles in the tomato germplasm and ...
Although domesticated tomato is cultivated by wild tomato, there are a lot of differences between cultivated tomato and wild tomato, such as shape, physiological function and life history. Many studies show that wild tomato has better salt resistance and drought resistance. In addition to, domesticated tomato's fruit is bigger and has more nutritious than wild tomato. The different features are...
Reduction of acrylamide formation in potato chips was investigated in relation to ten pretreatments before frying. Potato slices were fried at 170 C for 5 min. Prior to frying, potato slices were soaked in one of the following solutions for 60min : (1) tap water ; (2-4) NaCl solutions (1%, 2% and 3%); (5-7) citric acid solutions (0.5 %, 1 % and 2%); (8) combined solution (NaCl 3% +0.5% citric a...
Producing tomato is a daunting task as the crop of tomato is exposed to attacks from various microorganisms. The symptoms of the attacks are usually changed in color, bacterial spots, special kind of specks, and sunken areas with concentric rings having different colors on the tomato outer surface. This paper addresses a vision sensing based system for tomato quality inspection. A novel approac...
High temperature is the prevalent characteristic of subtropical and tropical regions and higher temperature has become an important limiting element for tomato production and yield. Although, tomato crops exhibit anatomical, morphological, physiological, phonological, and molecular responses to tackle with heat stress, but their reproductive stage and yields are extremely influenced by the high...
