Abstract:
Taking ‘Bofeng’ walnut of 3-years-old as material，effect of IAA and 6-BA on photosynthetic characteristics in foliar spraying by using portable photosynthesis system LI-6400 were studied．The results showed that spraying 100 mg/L AA to ‘Bofeng’ walnut could improve their ability to adapt to light environment，while spraying 100 mg/L 6-BA role was not very clear.After spraying 100 mg/L IAA its diurnal variation of a single peak，the net photosynthetic rate was significantly higher than the the control group，its maximum value higher than the control group 10.699 μmol?m-2.s-1；and after spraying 100 mg/L 6-BA its diurnal variation curves for the bimodal curve，there was a clear midday depression，but the net photosynthetic rate was closer to the mean of the control group.
