稀土浸种对水旱地小麦根苗生长及产量的影响
Effects of Soaking Seeds with Ree Solution on Growth of Wheat Root and Shoot and Yield Under Different Water Conditions
摘要
Abstract
The material used in the experiment was winter wheat 031165,cultivated by Shanxi Agricultural University and growed under drought stress and normal conditions respectively.The effects of seed-soaking with ree (Ce、La)on growth of wheat root and shoot and activity of antioxidase system were studied.Ree solution [La (NO3 )3 ,Ce (NO3 )3 ] of concentration 1 000 mg/kg was used for soaking seeds.The results showed that:drought stress inhibited the growth of wheat root and shoot,reducing the actual production of wheat.Soaking seeds with ree solution could significantly im-prove plant height,dry weight of shoot,leaf area and root biomass during all growth stages of wheat under whether drought stress or not.It could also improve SOD,POD activity in flag leaves,decrease intracellular content of MDA,and significantly increase wheat yield and economic coefficient,even more obviously under drought stress.On the whole,seed-soaking with Ce had a more positive effect on wheat growth,compared with seed-soaking with La.关键词
