英文摘要

Seed germination of Allium truncatum and Allium rothii from natural populations in the Negev were compared over a range of NaCl concentrations, naturally fluctuating or constant temperatures, light and dark. No germination occurred after the first 7 days of imbibition. The fastest germination was at 10 and 15 degrees C but there was none at 25 degrees C. The higher the NaCl concentration, the lower the germination. Allium truncatum plants inhabit wadis with crowded vegetation and the seeds germinate in the dark better than in the light, in natural and constant temperatures. Allium rothii plants inhabit open areas. There is no difference between germination in light and dark, in constant 5 to 15 degrees C. Germination at 20 degrees C in light is higher than in dark and in naturally fluctuating temperatures the germination in dark is higher.
