Mineral and heavy metal in grape flesh of different cultivars were measured by inductively coupled plasma-optical emission spectrometer. Eight grape varieties including four wine grapes (Cabernet Sauvignon, Cabernet Franc, Merlot, Cabernet Gernischt) and four table grapes (Muscat, Red Globe, Vitis labruscana Kyoho, Milk grape) from China’s main grape planting region, Changli, Hebei province were investigated. Concentrations of calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), nickel (Ni), lead (Pb) and zinc (Zn) were measured. All the parameters investigated in this study significantly changed depending on the cultivar. The minor and heavy metal levels for grape were determined between 5.68 and 15.11 mg/kg Cr, 6.56 and 19.85 mg/kg Cu, 96.79 and 172.15 mg/kg Fe, 6.54 and 25.23 mg/kg Mn, 3.70 and 5.89 mg/kg Ni, 0 and 1.64 mg/kg Pb and 4.29 and 13.44 mg/kg Zn. K ranged from 7,622.87 to 15,276.51 mg/kg and Na concentration ranged from 8,932.82 to 54,343.4 mg/kg. Cadmium was not detected at all.

A micropropagation protocol was developed for multiplication of seedless lemon (Citrus limon L. cv. Kaghzi Kalan) using nodal explants. The maximum shoot regeneration was observed on low level of BAP (0.1 mg l−1) or kinetin (0.5 mg l−1). BA was recorded to be better than kinetin in terms of ... more
The objective of this study was to evaluate the activity, kinetic behavior, and thermal inactivation kinetics of peroxidase (POD) in aqueous extracts from two kinds of milk ripe stage corn, sweet corn and waxy corn. Optimum activities using guaiacol as the hydrogen donor were obtained for s ... more
