摘要:
选用黑龙江省春小麦育种史上有典型代表性的8 个春小麦品种, 结合高产、超高产小麦育种目标, 分析了不同春小麦品种的产量特点及灌浆特性。结果表明:春小麦克丰4 号、克旱16 随着密度的增加产量明显增加,达到超高产的水平。8 个春小麦品种的主穗籽粒干重变化可以用log istic 方程拟合, 均呈“ S” 曲线, 其灌浆速率均呈单峰曲线, 但峰值的大小与达到最大灌浆速率的时间不同。克旱16 的灌浆速率为最高, 可达0.1195 mg ·d -1 ;而克丰4 号是早熟、小粒、密植型品种, 其特点是籽粒达到最大灌浆速率的时间提早, 开花后12.6 d 时达到最大灌浆速率, 保证有效灌浆时间。
Abstract:
The experiment selects 8 spring wheat varieties which was the ty pical representative in spring wheat breedinghistory of Heilo ngjiang .Combined with hig h yield or super hig h yield wheat breeding goal, the different spring w heat varietyoutput characteristic and the g rain filling characteristics were analyzed.The results indicated that the yield of KefengNo .4 and Kehan 16 obviously increased with the density , reached super high yield level.The dry weight changing ofmain spike could be fitted by the logistic equation , presented a shape of “ s” , its filling speed assumes unimodal curve , butthere was some differences between the peak value size and the time of maximum g rain filling .The g rain filling speed ofKehan 16 was the highest, may reached 0 .1195 mg·d-1 ;Kefeng No .4 is the early maturity , small seeds, and the clo seplantingvariety , the time reached maximum g rain filling speed alway s ahead o f others, 12 .6 d after anthesis achieve themaximum g rain filling speed and guarantee effective grain filling time .
