摘要

This paper forms the second part of a series of investigations on the control of the breaking of dormancy in barnyardgrass (Echinochloa Crusgalli Beauv. var. oryzicola Ohwi) seed. This investigation evaluated the change of the dormancy-breaking effect of several inhibitors against oxidation-reduction system through the process of the breaking of dormancy. 1) In deep dormancy stage, 8-oxyquinoline, KCN, DIECA, HgCl2, Na2S and salicylaldoxime-all showed a stimulative effect on the breaking of dormancy in considerable degree. But thiourea, NaN3 and BAL had no effect. 2) In deep dormancy stage, the inhibition of oxygen uptake by salicyladoxime, DIECA or HgCl2 was no more than 30 percent under the treatment inducing the dormancy-breaking effect. In addition, thiourea did not inhibit the oxygen uptake under the same treatment. 3) In shallow dormancy stage, the dormancy-breaking effect of KCN and HgCl2 increased remarkably. However, 8-oxyquinoline, DIECA and salicylaldoxime showed less effect than KCN and HgCl2. 4) The effect of 8-oxyquinoline in shallow stage was inferior to the level in deep stage by all means of treated period or concentration. 5) On the contrary, NaN3 had a noted effect only in shallow stage. These results indicate that the endogenous mechanism of dormancy in barnyardgrass is changing gradually, corresponding with the environmental conditions.
