| 摘 要： | 采取大田与盆栽相结合的方法，研究了不同品质类型冬小麦根系的基本特征，结果表明，品质类型不同，根系基本性状不同，中筋小麦豫麦49号除越冬初期外，其它各时期单株次生根条数均为最少，单株根干重介于豫麦34号及豫麦50号之间，单根质量高；越冬初期至挑旗期根系生理活性变化幅度大；弱筋小麦豫麦50号除越冬初期外，其它各时期单株次生根条数均最多，单株根干重各时期均为最大；拔节前根系活力最弱，挑旗后根系活力下降幅度较大，根中SOD活性罪状强且各时期变化幅度不大；强筋小麦豫麦34号，单株根干重量小，根系质量最差；拔节前根系活力较强，拔节后根系活动较弱，下降速度缓慢，根中SOD活性各时期变化幅度较小。 |

| Abstract: | The field experiment was combined with the pot experiment to study the root system characters of different quality types of winter wheat.The results indicated that different quality type of wheat had different root system characters. The secondary root number per plant of Yumai No 49,a mid strength quality wheat,is the smallest among the three varieties except the winter stage but its root system quality is the best;the intensity of reducing TTC and the activity of SOD of fresh wheat root are the highest during the period from winter stage to flag leaf stage.Since flag leaf stage,its physiological characters are weaker and have bigger variation during whole stage.The secondary root number per plant of Yumai No 50,a soft quality wheat,is the biggest except during winter stage,and its dry weight of root of single plant is the heaviest in every stage.Before 19th,March,its intensity of reducing TTC is the weakest and decreases abruptly after flag leaf stage,but its activity of SOD decreases slowly.Root dry weight per plant of Yumai No 34,a high quality wheat,is the smallest among the three varieties and its root system quality is the weakest.Before jointing stage,the intensity of reducing TTC is stronger,but after that,it decreases slowly though it is smaller,and the activity of SOD decreases slowly in every stage. |
