The differences of Mo uptake and distribution in Mo-efficient winter wheat cultivar 97003 and Mo-inefficient winter wheat cultivar 97014 were studied in two treatments. Molybdenum (Mo) was applied at the rate of 0(control) and 0.13 mg·kg-1 to an acid yellow-brown soil (soil available Mo 0.112 mg·kg-1). The results showed that the accumulation of Mo and dry matter in shoots of cultivar 97003 was significantly higher(P<0.01) than in cultivar 97014 in the entire growth period in control. Cultivar 97003 also ha...
