摘    要:选用高油花生品种豫花15和高蛋白品种XB023,研究了土壤不同浓度镉胁迫对花生生理特性和产量品质的影响。结果表明, 轻、中度镉胁迫(1.0 mg kg–1和2.5 mg kg–1)促进花生营养生长,重、高度镉胁迫(7.5 mg kg–1和15.0 mg kg–1)抑制营养生长;轻、中度镉胁迫增加XB023的叶绿素含量,重、高度镉胁迫降低两品种叶片叶绿素含量和净光合速率。镉胁迫降低了两品种荚果和籽仁产量,豫花15在中度镉胁迫(2.5 mg kg–1)下产量即开始明显降低,而XB023在重度镉胁迫(7.5 mg kg–1)时产量才开始显著下降。镉胁迫对花生不同品质类型品种的影响不同,镉胁迫增加了豫花15的籽仁可溶性总糖含量,降低了脂肪、蛋白质含量及油酸/亚油酸(O/L)比值;降低了XB023籽仁中可溶性糖含量、脂肪含量及O/L比值,轻、中度镉胁迫可增加籽仁蛋白质含量及赖氨酸和苏氨酸等氨基酸组分。镉胁迫导致花生体内镉含量增加,豫花15植株内镉含量高于XB023,但籽仁中镉含量小于XB023。

关 键 词:花生  镉胁迫  生理特性  产量  籽仁品质

Abstract:A pot experiment was carried out to study the effects of different cadmium concentrations on peanut physiological characteristics,yield and quality using peanut cultivars of Yuhua 15 and XB 023.Five Cd concentrations [0 mg kg-1(CK),1.0 mg kg-1(light Cd stress),2.5 mg kg-1(medium Cd stress),7.5 mg kg-1(heavy Cd stress),and 15.0 mg kg-1(high Cd stress)] were treated by basal dressing in 2009 and 2010.The results showed that light and medium Cd stresses could promote peanut vegeta-tive growth,but heavy and hig...
Keywords:Peanut  Cd stresses  Physiological characteristics  Yield  Kernel quality
