Effect of nitric oxide(NO) fumigation for different period on the post harvest quality of tomato
Tomato fruits were fumigated for a series of periods of 20 μL/L nitric oxide(0.5,1,1.5,2 h) to investigate the effect of nitric oxide(NO) fumigation with different period on the post harvest weight loss,respiration,pulp hardness and soluble solids of tomato.The results showed that:NO fumigation for 1~2 h could effectively inhibit the post harvest weight loss and pulp hardness of tomato.Meanwhile,the post harvest respiration and the total soluble solids loss of tomato were also controlled,which suggested that the treatment of NO fumigation could postpone the progress of post harvest ripeness and senescence of tomato.However,NO fumigation for 0.5 h had no significant effects on the post harvest quality of tomato.
