Germination and seedlings growth of domestic poppy (Papaver somniferum L.) regarding salinity and temperatures

In this research there were studied the effects of NaCl-induced salinity and environment temperatures on germination seedlings growth domestic poppy. The study was conducted in controlled conditions plant chamber. There applied different concentrations NaCl (0 mM (control), 50 mM, 100 150 mM) (10°C, 15°C 20°C). seeds poppy cultivar (Detkovac) sown 4 replicates filter paper. energy determined 5th day total rate morphological characteristic 10th day. At average 28%. It interesting to note that at 10°C no germinated after 5 days all treatments also, level every temperature. (on day) 52% it varied from 30% (150 20°C) 90% 15°C). Different water solution had a very significant (p<0.01) influence stem, root length (cm) seedlings. 1.3 cm 0.9 (100 NaCl) 1.8 NaCl). stem cm. longest found control (2.7 cm), between difference not averaged 1.4 depending Average 3.0 4.5 2.3 NaCl. With regard temperatures, differences seedlings, but for length. measured 20°C 0 (4.9 while or NaCl, less than 0.1 Seeds germinating both, Generally, reduced Results may indicate are mainly affected by osmotic stress therefore is recommended cultivate poppies soils with excess salts
