| Abstract: | The acid phosphatase(APase) activity of winter wheat( Triticum aestivum L.)cv. Linfen 118 with high phosphate use efficiency (PUE) was changed with two peaks during life period,in comparison with a low PUE cultivar Lumai 13,the APase activities in functional leaves were lower before filling stage but higher after that. The APase activity of cv. Lumai 13 was changed with only one peak and increased with the application of P fertilizer,indicating that Lumai 13 was sensitive to fertilizer. The correlation between the APase activity of the top third leaf and PUE was significant( R =0.944,P <0.1),so the APase activity of the top third leaf could be used as an index for screening wheat genotypes with high PUE. |
