Thin cell layers (TCL) of Nicotiana tabacum L. cv. Samsun were cultured in vitro to evaluate the effect of the pH of the culture medium and ionic uptake on vegetative organogenesis. The chromatographic analysis showed important variations during culture in the concentrations of the ions in the tissues of the explants grown at different pH levels. After 25 days of culture, shoots with regular development...
A dose-response study with the anti-ozonant ethylenediurea (EDU) and a near-ambient level of ozone (6-h mean of 48 nmol mole -1 per 6 days each week) was performed in closed chambers on Phaseolus vulgaris L. cv. Lit. Analyses of morpho-functional parameters and biomass measurements were conducted when plants had reached pod maturation (green harvest). The exposure to ozone caused the...
