| 摘 要： | 油菜花粉萌发率与培养基中蔗糖和硼酸浓度均呈一元二次函数关系。花粉萌发率最高的蔗糖和硼酸浓度分别是12.5％和131ppm,土壤硼不足(含水溶性硼0.2ppm)时萌发率为13.1％,土壤硼适量(硼0.7ppm)时为46.2％,土壤硼过量(硼1.5ppm)时为34.8％,与硼不足的相比,差异达极显著和显著水平。

| Abstract: | The relationship between rape pollen germinating rate and concentration of sucrose or boron acid in incubation media was a quadratic function with one unknow quantify,respectively.A highest germinating rate was found when in the incubation media there were 12.5%sucrose and 131ppm boron acid.Under boron-deficient(0.2ppm water solubl-e boron in soil),boron-stifficiet(B 0.7ppm)and boron-excessive(B 1.5ppm)condition,the germinating rate was 13.1%,46.2% and 34.8%respectively.Comparing with the boron-deficient condition,the difference of the last of two treatments showed very significant or significant respectively. |
