| 中文摘要: |
| 小黑麦籽粒不饱满是制约其应用开发的主要因素。为了解决这个问题，本试验以小黑麦东农8809和东农95-6654为试验材料，研究外源赤霉素（GA3）作用下小黑麦籽粒干物质、灌浆速率及产量的变化，并探讨开花期喷洒外源赤霉素对小黑麦籽粒灌浆特性及产量的影响。结果表明，开花期适量赤霉素处理能提高小黑麦籽粒灌浆速率，加速籽粒灌浆进程，促进干物质向籽粒中运转，进而提高粒重及产量。20 mg·L-1赤霉素喷施调控效果最好。 |
| 英文摘要: |
| Non plumpness grain has becoming a major restricting factor for the application scale and development space of triticale. Triticale varieties Dongnong 8809 and Dongnong 95-6654 were used as materials, the grain dry matter accumulation, grain-filling rate and yield of triticale were investigated under the application of exogenous GA3 in order to understand the effects on grain-filling and yield under the regulation of GA3 at anthesis. The results indicated that appropriate amount of GA3 at anthesis increased the grain-filling rate of triticale, accelerated the grain-filling process and promoted the transportion of dry matter to grain, then increased the grain weight and yield. In this test, the concentration of GA3 20 mg·L-1 was the best. |
