| Abstract | ||||
| Thirty six surface soil samples and the same number of plant samples of Egyptian berseem (Trifolium alexandrinum) (2nd cut), parsley (Petroselinum crispum Mill) and rocket (Eruca vesicaria L.) plants from twelve sites from Giza governorate were collected in January 2001; i.e three plant samples with their three soil samples from each site. Soil available Se was extracted using AB-DTPA. Soil and plant Se was measured spectrophotometerically. The results showed that the soils of Giza governorate are relatively low CaCO3, medium salinity level and relatively high clay content. The average values of dry weight percent for berseem, parsley and rocket were 10.56, 6.24 and 6.65%. The values of available Se are very low (the averaging equal 0.013 µg.g-1) and correlated more or less negatively with soil EC. The average values of Se concentration in berseem, parsley and rocket plants are 0.083, 0.045 and 0.038 µg.g-1. Thus, available Se positively and significantly correlated with Se in berseem, parsley and rocket plants, where the correlation coefficient values are 0.632*, 0.607* and 0.603* respectively. Thereafter, a linear regression behaviour could be found between available Se and those of berseem, parsley and rocket. | ||||
