Dormienza e alotolleranza in due specie spontanee di Hordeum (H. murinum L. e H. marinum Huds.)

摘要: Abstract Dormancy and salt-tolerance in two spontaneous species of Hordeum. — behaviour germination capacity salt-solutions Hordeum murinum L. marinum Huds. seeds have been studied. Seeds (caryopses) sown Petri dishes on filter paper soaked with deionized water (control) or NaCl solutions at concentrations: 3.2 - 6.5 13.0 26.0%. Germination was tested during after-ripening, 20, 40, 60, 100, 160, 260 365 days from harvest (fully ripe seeds). The are characterized by peculiar ecological features. present results shown that, the first year harvest, H. different length strength dormancy (longer stronger than murinum). energy after-ripening stage when differ strongly seem to be correlated dormancy. seeds, which exhibit a ...
