重金属低积累玉米品种的稳定性和环境适应性分析
The Analysis of Stability and Adaptability on Low Accumulation of Heavy Metals in Various Cultivars of Zea Mays
摘要
Abstract
Five widely planted locally maize cultivars(Nol :Zhenghong 311; No2;Chengdan 30; No3: Chuandan 428; No4;Longdan 8; No5: Chuandan 418), as experimental materials, were planted in seven experimental sites in Shehong County in Sichuan Province, and AMMI Model and biplot pattern were used to evaluate how interaction of breed and environment affect Corn kernels' ability to accumulate heavy metals. Results from analysis through AMMI Model showed that as far as Corn kernels' ability to accumulate Cu be concerned, the contributions from breed, interaction of breed and environment and environment were 77.6%, 18.3% and 3.9% respectively; as for Corn kernels' ability to accumulate Cr, As and Pb, the contributions from breed were respectively 37.5%, 23.2% and 31.8%, the contributions from interaction of breed and environment were 57.5%, 63.4% and 50.3% respectively, the contributions from environment were 5%,13.4% and 17.9% respectively; for Hg and Zn, the contributions from environment were 16.8% and 19.2% respectively, and the contributions from interaction of breed and environment were 74.3% and 69.2% respectively. The results from analysis through bioplot pattern showed that as for the stability for Corn kernels accumulating As, No2>No3>Nol>No4>No5; as for Corn kernels' ability to accumulate As, No5>No3>Nol>No4>No2. As for the stability of Corn kernels accumulating Hg, No5>No3>No2>Nol>No4; as for Corn kernels' ability to accumulate Hg, No4>No2>No5> No3>Nol. As for the stability of Corn kernels accumulating Cu, No5>Nol>No4>No2>No3; as for Corn kernels' ability to accumulate Cu, No3>Nol >No4> No2 ≈ No5. As for the stability of Corn kernels accumulating Pb, No2>No5>No4>No3>Nol; as for Corn kernels' ability to accumulate Pb, No2>Nol≈No5>No3>No4. The stability of Corn kernels accumulating Cr and Zn, and Corn kernels' ability to accumulate Cr and Zn were not analyzed due to their effects not reaching significant level. This study was helpful for properly choosing maize cultivars so as to keep the heavy metals content at the safe level according to the impacts of breed, interact of breed and environment and environment on Corn kernels' accumulating heavy metals. At the same time, it was feasible that the AMMI Model is used to evaluate impacts of different factors on Corn kernels' accumulating heavy metals.关键词
