Abstract:
To assay the control efficiency of amino acid selenium foliar fertilizer to apple ring blight,apple (Malus domestica) ‘Nagafu 2’ was used to investigate the control efficiency of spaying amino acid selenium against apple ring rot.The results showed that the control efficiency was 20% against apple ring rot by spaying amino acid selenium at growing season of apple.However,the control efficiency of amino acid selenium was up to 90% when combined with thiophanate-methyl.This value was increased about 15% than that one of treated with thiophanate-methyl alone.More importantly,the activities of superoxide dismutase (SOD),peroxidase (POD),and catalase (CAT) as well as proline (Pro) content were significantly enhanced in apple fruits treated with amino acid selenium alone or in combination with thiophanate-methyl.The malondialdehyde (MDA) content was declined at the same time.In conclusion,the spaying amino acid selenium at growing season could enhance the control efficiency of fungicide.Furthermore,the amino acid selenium could increase the activities of defensive enzymes and reduce the accumulation of MDA.
