Abstract
In fruit tree crops such as pear and peach flower sampling can be carried out much earlier in the season than leaf sampling. We have explored the possibility of using the analysis of flowers (floral analysis) to predict the Fe content of leaves taken from the same trees 60 and 120 days after full bloom. The Fe concentration of flowers was well correlated with that of leaves taken 60 days after full bloom, both in peach and pear trees. The Fe concentration in flowers was also well correlated with that of leaves taken 120 days after full bloom in pear trees. Furthermore, the range of variation of Fe content in flowers was larger than that of leaves. These results suggest that floral analysis could be a good tool for the prognosis of Fe deficiency in fruit crops.
