Abstract:
The seeds of Spinacea oleracea,Chrysandthemum coron vium,Coriandrum satium were treated with GA3,Thiourea,KNO3 and H2O2 at various concentrations respectively.The results showed that GA3 slightly promoted at low concentration or inhibited athigh concentration the germination of three seeds,in contrast,the germination of three kind of seeds was promoted by usi ng Thiourea solution with optimal concentration of 0.2% for spinacea olera cea and coriandrum satium,0.5% for coriandrum satium KNO3 with 0.2% concentrationhad the best effect for three kind of seeds,but 30% H2O2 only had primitive ef fective for spinacea oleracea.Treatment with KNO3 Thiourea reduced electrolytes and UV absorbent substances leaked from the effective treated seed,which sugge sted that Thiourea,KNO3 can keep the stability of cell membrane.
