PROTEIN CONTENT AND COMPOSITION OF LEAVES AND SHOOT BARK IN RELATION TO ALTERNATE BEARING OF OLIVE TREES (OLEA EUROPAEA L.)

The protein content and composition of "on" and "off" olive trees was determined in the leaves and bark of one year old shoots.
Four cultivars, Koronaiki, Uovo de piccione, Manzanillo and Barnea were used.
The total extructable protein content in the leaves of "off" trees was considerable lower than in the leaves of "on" trees.
In the bark an opposite relation was found.
Leaves of cv.
Koronaiki, which is the least alternating cultivar showed the smallest difference.
In the bark however, all cultivars showed the same relation.
A greater amount of a 36 kd protein was found in the bark of the "off" trees of all cultivars than in that of the "on" trees of the same cultivars.
To a smaller extent a 66 kd protein was also stronger expressed in the bark of "off" trees.
In the leaves of "on" and "off" trees the differences of specific proteins was smaller involving mainly proteins
