Flesh of fruits

TCDD in the flesh of fruits and vegetables collected from the contaminated area In Seveso during 1977-1979, although the soil 2,3,7,8-TCDD concentration was 10 ppb. These authors concluded that 2,3,7,8-TCDD does not appear to be translocated from soil to the plants. A similar conclusion was reached by Pocchlarl et al. (81) from their uptake experiments with plants. As noted by EPA, It can be concluded from these studies that... 

Some of the genetic variations in which flavonoid compounds are concerned can be discerned by mere visual inspection such variations, for instance, as the presence or absence of red or yellow color in the skin or flesh of fruits others, such as astringency, can be discerned by simple organololeptic test. But when, as is frequently the case, the genetic situation is complicated, it may be important to the breeder to know, for instance, exactly what pigments are present in a particular strain, or how to detect variants possessing undeveloped characters which may be elicited in further crossings. 

The occurrence of inhibitors in the flesh of fruit is particularly well-known, They appear to be ecologically essential. The flesh of a tomato, for instance, ought to present the best preconditions for germination when no inhibitors are present—but that would be disasterous if the conditions outside the tomato were not favorable for further development of the seedling.
