Ethylene, a key factor in the regulation of seed dormancy

WebSolution: Ethylene is a simple gaseous plant hormone which is produced in large amounts by senescing organs and ripening fruits. It promotes abscission and senescence, fruit ripening, horizontal growth of seedlings, bud opening and seed germination but do not overcome apical dominance. Cytokinins help to overcome apical dominance. WebEthylene signaling appears critical for grape bud dormancy release.
