Tomatoes selected tomato cultivars

The range (p,g/100 fresh weight) of lycopene and P-carotene in selected tomato cultivars can be 20-62000 and 35-2200 respectively, and of P-carotene and a-carotene in selected carrot cultivars 1100-64000 and 530-36000 respectively. Some of the carotenoids may be present as fatty acid esters (Breithaupt and Bamedi, 2001). More extensive listings can be found (O Neill et al, 2001 van den Berg et al, 2000 Hart and Scott 1995).

Table IV. Total antioxidant activity of selected tomato cultivars...

Be sure you need the type of resistance that the cultivar you select offers. For instance, it s not necessary to plant a Verticillium-resistant tomato cultivar if your soil is not infested with Verticillium fungi. 

Sample heirloom cultivars for resistance. Heirloom plants that have been carefully selected and cultivated for many generations also may contain high levels of pest resistance. Some heirloom tomato cultivars, for example, have been screened and selected by gardeners for such a long time that they are naturally resistant to diseases such as Verticil-lium and Fusarium wilts. 

Different factors may influence the polyphenol content of tomatoes, the major being the cultivar followed by climatic conditions and maturity degree. Therefore, it was of interest to evaluate the polyphenol pattern of tomato cultivars selected among those mostly preferred by consumers or processed by food industry.

Furthermore, the total antioxidant activity (TAA) of the selected cultivars was assayed, and the obtained TAA values were correlated with the content of tomato components.
