| 摘 要： | 甜荞栽培种有长花柱(Pin,P型)和短花柱(Thrum,T型)两种花型,理论上两种花型比率约为1:1。田间调查发现：不同甜荞品种的花型比率略有不同,且花型比率的不同对甜荞的产量有较大影响。本研究以蒙0208、综甜2号、品甜荞1号3个甜荞品种为材料,以单株粒数和单株粒重两个产量性状为主要调查指标。通过构建T:P分别为1:9、2:8、3:7、4:6、5:5、6:4、7:3、8:2、9:1的甜荞花型比率,探讨甜荞花型比率与结实性之间的关系。研究结果表明：花型比率为4:6或6:4时,3个甜荞品种的两个产量性状表现最佳。当花型比率为1:1时,P型花植株的单株粒数和单株粒重优于T型花植株,某种花型的单株粒数和单株粒重一般是在其占比少的时候表现更好。通过本试验可以推断,当群体中T花型的比率高于80%时,甜荞的产量明显降低。

Effect of Flower Type Ratio on Yield Traits of Common Buckwheat |
| |
| Abstract: | There are two flower types including thrum and pin in buckwheat ,it’s ratio will be approximately 1 to 1 theoretically.the earlier stage research showed that the different varieties of buckwheat existed different ratios among the thrum and pin and different ratio would affect the yield of buckwheat dramatically.this trial used three different varieties introduced from inner Mongolia ,guizhou province and our institute as basic research materials . By setting up the different flower type ratio in which T:P is 1:9 ,2:8 ,3:7,4:6,5:5, 6:4,7:3,8:2,9:1 separately. This experiment was evaluated the seed set by the grain per plant and the weight per plant and discussed the relationship between flower types and seed setting. The result shows that three varieties express high seed setting when the flower type ratio is 4:6 or 6:4, the pin plant have better seed setting than thrum plant when the flower type ratio is near to 1:1. The seed setting would express much more better when this flower type is less in this treatment. it inferred that the buckwheat yield will be reduced when the thrum plant occupied over 80% in the group. |
