Effect of hexavalent chromium on the growth and physiological and biochemical parameters on Brassica oleracea L. var. acephala DC.

In order to determine the toxic effect of chromium Cr(VI) on the seed germination, the root and shoot length, the root-cotyledonary leaves, the fresh and dry weight in eight-day-old seedlings Brassica oleracea L. var. acephala DC (kale) were treated with various concentrations of Cr in the growth medium.

Effect of salinity and temperature on the germination of Spergularia marina seeds and ameliorating effect of ascorbic and salicylic acids.

Spergularia marina (Caryophyllaceae) is a halophytic species and widely distributed among the sea shores of Turkey. Its seeds maybe unwinged or winged. Laboratory experiments were conducted to determine the effects of salinity (0, 50, 100 and 500 mM NaCl) and temperature (10, 15, 25, 30, 35 degrees C) on seed germination.
