A multi-spectral fluorescence imaging technique was used to detect defective cherry tomatoes. The fluorescence excitation and emission matrix was used to measure for defects, sound surface and stem areas to determine the optimal fluorescence excitation and emission wavelengths for discrimination. Two-way ANOVA revealed the optimal excitation wavelength for detecting defect areas was 410 nm. Pri...

With the aim of estimating the growth of tomatoes during the agricultural season, we propose to segment tomatoes in images acquired in open field, and to derive their size from the segmentation results obtained in pairs of images acquired each day. To cope with difficult conditions such as occlusion, poor contrast and movement of tomatoes and leaves, we propose to base the segmentation of an im...

T o m a t o products, including ketchup, tomato juice, and pizza sauce, are the richest sources of lycopene in the U.S. diet, accounting for greater than 80 percent of the total lycopene intake of Americans. In addition to tomatoes (Lycopersicon esculentum) and tomato-based products, lycopene is also found in watermelon, papaya, pink grapefruit, and pink guava. Lycopene from both processed and ...

Five different serotypes of Salmonella enterica were implicated in a large outbreak linked to fresh Roma tomatoes served at gas station deli counters in Pennsylvania and nearby states during July 2004: S. enterica serotypes Javiana, Anatum, Thompson, Typhimurium, and Muenchen. One of these serotypes, Anatum, was isolated from both tomatoes and patients. Pulsed-field gel electrophoresis (PFGE) p...

Recently, it started gaining more medicinal value because of the antioxidant property because of ascorbic acid and lycopene content (Anon., 2000). Hence tomatoes are called as poor man’s apple (Rick, 1969). Tomatoes offer significant nutritional advantages, including providing a significant source of dietary lycopene, β-carotene, carotenoids, vitamin C, potassium, fiber, color, flavor and antio...

We explore the generality of Konrad and Lommerud (1995)’s Rotten Spouse Theorem. While the result holds for an arbitrary number of agents, it fails to hold for general technologies. We discuss some of the implications for CO2-emissions models.

Physiological studies of strongly photoperiodic species in lonig alnd short day have hitherto dealt predominiantly with the effect of day length upon development rather than uponl growth. In photoperiodic species which flower in only one of two contrasted day lengths, it becoiles difficult to compare or interpret data on growth due to simultaneous developmental differences of plants grown in un...
