Peg 8000

Two durum wheat (Triticum durum Desf.) cultivars were tested for salt and drought tolerance at germination, seedling emergence and early seedling growth in NaCl and PEG-8000 solutions of different osmotic potentials (–0.2, –0.4, –0.6 and –0.8 MPa). Daily and final germination and emergence percentage, as well as germination and seedling emergence rate, seedling growth, fresh and dry weight were recorded under controlled conditions. Results showed that germination and emergence rates were delayed by both solutions in both cultivars, but Omrabia showed higher germination and emergence rates than BD290273 in NaCl while BD290273 was less affected by NaCl and PEG solutions at the emergence stage. Sodium chloride had a lesser effect on both cultivars in terms of germination rate, emergence rate, final germination and emergence percentage than did PEG-8000. This conclusively proves that the adverse effect of PEG-8000 on germination, emergence and early seedling growth was due to the osmotic effect rather than to the specific ion. Seedling growth was reduced by both stresses. However, NaCl usually caused less damage than PEG to durum wheat seedlings, suggesting that NaCl and PEG acted through different mechanisms.

Postemergence applications of flufenprop-methyl [methyl-N-benzoyl-N(3-chloro-4-fluorophenyl)-2-amino-propionate] for wild oat (Avena fatuaL.) control in spring wheat (Triticum aestivumL.), durum wheat (Triticum durumL.), and barley (Hordeum vulgareL.) were evaluated in the field, greenhouse, and controlled environmental chambers. Wild oat control with flufenprop-methyl was greater at the five-leaf stage than three and one-half or two-leaf stage of growth. Wild oat control was not reduced when flufenprop-methyl was tank-mixed with bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4) 3H-one, 2,2-dioxide]. Tolerance of spring and durum wheat cultivars to flufenprop-methyl was acceptable; however, tolerance of barley cultivars was considerably more variable. Air temperature after treatment, soil fertility, and moisture did not influence wild oat control with flufenprop-methyl; however, a simulated rainfall of 1 mm within 1/2 h or 4 mm within 4 h after application reduced wild oat control.

Early Seedling

We studied the effects of three salinity levels (50, 100 and 150 mM NaCl) on the early seedling growth of three wheat (Triticum aestivum L.) cultivars of Albanian origin characterized by different sensitivities to salt. Sodium accumulation was similar in seedlings of different cultivars and, in general, Na+ was confined to the root. Chloride accumulated at high levels in both the root and the shoot but least so in Daity. No appreciable differences were observed in K+ content. The most salt-tolerant cultivar showed a higher capacity for osmoregulation than the other two cultivars. Key words: Ion regulation, ion toxicity, osmoregulation, salinity, Triticum aestivum
