Tomato ( Solanum lycopersicum L.) is one of the most important vegetable food crops of the world ( FAOSTAT, 2008 ). Year-round availability, a high rate of consumption, and significant levels of antioxidants such as ascorbic acid, β-carotene, γ

, Si concentrations in the leaves exceed those of macronutrients ( Epstein and Bloom, 2005 ; Zellner et al., In press). Tomatoes ( Solanum lycopersicum L.) have been referred to as Si excluders or nonaccumulators because previous studies showed that Si

Tomato ( Solanum lycopersicum L.) is an important fruit for human consumption because it provides nutrients like flavor compounds, vitamins, and fiber ( Beecher, 1998 ). Postharvest ripening and senescence involve changes in metabolism and gene

subspecies Solanum lycopersicum var. cerasiforme ranges throughout much of South and Central America and represents the closest wild gene pool for the introgression of novel traits into cultivated tomato. Many S. l. var. cerasiforme accessions are

abscission during storage. Materials and Methods Plant material and growth conditions. Tomato plants ( Solanum lycopersicum L. cv. Bandita) were grown on a hanging-carrying system with high wire support training in coco–peat media. Bunches were hand

In 2004, more than 4 million ha of tomato ( Solanum lycopersicum ) were cultivated worldwide, producing over 116 million tonnes ( FAO, 2005 ). This crop is the second horticultural species in terms of cultivated surface area and production volume

, Solanum melongena , Solanum lycopersicum , Nicotiana tabacum , and Capsicum annuum , as well as numerous toxic or poisonous species. Puerto Rico is considered a biodiversity hotspot due to its tropical location and the high concentration of endemic

variability ( Nieuwenhof et al., 1993 , 1997 , 1999 ). Wild tomato relatives such as Solanum peruvianum , Solanum chilense , and S. habrochaites show a wider range of optimal temperatures for growth and reproduction compared with S. lycopersicum
