Potassium chloride, Na-pyrophosphate, CuCl2, NH4-oxalate, dithionite-citrate-bicarbonate (DCB) and Na-citrate solutions were employed to extract aluminum (Al) and iron (Fe) sequentially and separately from 15 acidic soils located at the Mangshan Mounta

1-4℃低温处理西葫和茄子,其幼苗生长明显受抑.低温处理到4d时,分别检测两种作物幼苗根系和胚轴过氧化物酶(POD)、细胞色素氧化酶(COD),苹果酸脱氢酶(MDH)的同工酶.结果发现,COD同工酶只在西葫根系中发生一些变化,POD和MDH同工酶变化明显.西葫胚轴POD,根MDH和茄子胚轴POD均有谱带增加或消失现象,这是低温诱导的结果.
