| 摘要: |
| 在控制条件下，以CaCN2（0，1.50，2.00，2.50 mol/L）、H2CN2（0，0.12，0.24，0.36，0.48 mol/L）、硫脲(0，0.13，0.26，0.39，0.53 mol/L)处理黑虎香和霞多丽葡萄的双芽枝条,研究各药剂不同浓度处理对葡萄休眠枝条的作用效果。结果表明，在萌芽整齐度指标上，CaCN2优于H2CN2和硫脲，但最大萌芽率之间差别较小。对单一药剂，促进萌发效果随药剂浓度增加而增大，但最大萌芽率没有差异。 |

| Abstract: |
| Under controlled condition,the result of treatments of CaCN2（0，1.50，2.00，2.50 mol/L）,H2CN2（0，0.12,0.24，0.36，0.48 mol/L）,thiourea (0，0.13，0.26，0.39，0.53 mol/L) on two-bud cuttings of‘Fox’and‘Chardonnay’grapevines indicated that CaCN2 expressed more stronger effect on prompting budbreak than Dormex and thiourea,but there was little difference among the maximum budbreaking rate.The effect of every chemical on budbreak was enhanced by the increase of concentration,but the maximum budbreak was close. |
