Potential Effect of Ethephon on Harvesting and Ripening of Walnut
An investigation was made to explore the potential effects of ethephon on the harvesting and ripening of walnut.Different concentrations of ethephon were used to accelerate the ripening of walnut.The results showed that the low concentration of ethephon spray shared the better effect on the falling of walnut compound leaves,while less effect was found on the flower and leaf buds.High concentration of ethephon was induced the apoptosis of flower and leaf buds of walnut in the next year,leading to the reduction of yield.The excessive pesticide residues were observed in the walnut kernel at high concentration of ethephon spray,where the nuts were red or green on the surface.The findings can provide a strong reference for the application of ethephon in walnut production.
