Abstract:
In order to explore a new approach of correcting iron deficiency chlorosis in apple trees,the effect of Fe-N solutions which was our homemade by siphon transfusion following trunk was studied,contrasted by transfusing water and conventional management.By analyzing the degree of yellow leaves,the diversification of chlorophyll content,the feature of FCR activity in normally green leaves and yellow leaves and the activity of FCR in different treatments leaves.The results showed that the degree of the chlorosis was resumed from 2.00 to 0.49 after transfusing Fe-N solution 10 days;chlorophyll a and chlorophyll b content increased by 47.98% and  107.70% than the conventional management,and reached a significant level,that showed that the treatment of siphon transfusion following trunk could achieve a significant re-green effect in a short period of time.The red circle around yellow leaves were much stronger than normal leaves in the characterization test of FCR.The FCR activity of the comparison was significantly higher than the treatment of siphon infusion,which described that the situation of iron deficiency could improve the activity of FCR,thus that revealed the system response of Fe2+ into the mesophyll cells,and clarified the mechanism of Fe into the mesophyll cells by siphon transfusion following trunk,and provided a theoretical basis to better utilize the technology of siphon infusion to correct iron deficiency chlorosis in apple,and it showed the feasibility of the technology of siphon transfusion following trunk correcting iron deficiency chlorosis in apple.
