Morpho-physiological and Antioxidants Enzymes Response in Sc

農田土壤鎘毒對植物動物的影響引起全球學者注意。通過四個相關且獨立的實驗,探討不同程度鎘毒的土壤動態(tài)變化,以及不同條件下香稻品種對鎘毒的響應。采用五個香稻品種(V1:美香占2號,V2:象牙香占,V3:桂香占,V4:巴斯馬蒂,V5:農香18),設置四個鎘濃度梯度,分別為0、50 mg/kg-1、100 mg/kg-1、150mg/kg-1,通過盆栽實驗檢測鎘對香稻幼苗生長期的影響。實驗測定了在不同濃度Cd脅迫下水稻苗期抗氧化酶活性、脂質過氧化作用中丙二醛(MDA)、過氧化氫(H2O2)含量、生長參數(shù)如株高、總干物質含量、水稻秧苗期鎘吸收量。結果表明,抗氧化酶活性隨著土壤Cd濃度增加而下降。Cd脅迫下水稻脂質過氧化作用與Cd濃度相關。所有水稻品種的根系、莖Cd吸收量隨著土壤Cd濃度增加而增加,根系吸收比莖高,V1和V5的根莖葉吸收量最高。V3各部位積累Cd較少。結果顯示,土壤鎘毒對水稻生長有負效應。水稻根吸收Cd比莖多且每個品種吸收效果不同?傮w而言,鎘毒阻礙水稻苗期生理生化生長,但V3耐鎘毒害效果比其余四個好。采用五個香稻品種(V1:美香占2號,...
