| 中文摘要: |
| 以18个具有不同HMW-GS组成类型的春小麦为材料,在同一氮素水平条件下研究不同形态氮肥对春小麦籽粒蛋白质含量、干面筋与湿面筋含量和SDS沉降值4项品质指标的调节效应。结果表明,各项品质指标适宜的氮肥形态具有一定差异。氮肥形态和HMW-GS组成类型对籽粒蛋白质含量、干面筋与湿面筋含量的影响较小,而对SDS沉降值影响较为明显,但更主要受品种(品系)自身遗传特性的影响。 |
| 英文摘要: |
| The effects of different kinds of nitrogen on quality characteristics of spring wheat,such as protein content,dry gluten,wet gluten and SDS-sedimentation value under the same amount of nitrogen were studied.Eighteen cultivars (lines) differing in HMW-GS composition were used.The results showed that all kinds of quality characteristics had different befitting nitrogen kind.Although there was no significant effect of different kinds of nitrogen and HMW-GS composition on protein content,dry and wet gluten and SDS-sedimentation value was controlled significantly by different kinds of nitrogen and HMW-GS composition,and quality characteristics would be mainly controlled by the genetic characteristic of cultivars(lines). |
