Evaluation of lime induced iron-deficiency chlorosis tolerance of peanut on calcareous and purplish soil in Sichuan
摘要
Abstract
The lime induced iron deficiency chlorosis of peanut occurs commonly in calcareous,alkaline and purplish soils of Sichuan Basin.Iron-deficiency induced chlorosis tolerance of 19 peanut genotypes were investigated in 2010 and 2011.The results showed that:1) the occurrence rate of the chlorosis were significantly different among the developmental stages and maximized at 75 days after sowing date at pod setting stage ; 2) the tolerance to iron deficiency among 19 genotypes were markedly different,the genotype ICGV 86031 was free from the symptoms and had maximum SPAD; 3) the variances of the chlorosis tolerance and yield among genotypes had significant quadratic parabola or linearity correlation at 1％ probability level; 4) ICGV 86031 was iron efficient,but low yielding,while ICGV 97228,97229 and 97232 were iron sensitive and had the most yield reduction in the calcareous and purplish soil.Tianfu 24 tolerated iron deficiency well with higher yield.关键词
