CHANGES IN PROTEIN CONTENT AND OXIDASES ACTIVITIES WITH FRUIT DEVELOPMENT AND RIPENING IN THE LEAVES AND FRUITS OF OLIVE (OLEA EUROPAEA L. CV. ZARD) DURING "ON" AND "OFF" YEARS N. MOTAMED, H. EBRAHIMZADEH* AND SH.MONTASSER-KOUHSARI
Abstract: Results of the studies on olive trees from four regions of Iran (Roudbar,
Gilvan, Gorgan, and Zanjan) indicate that soluble protein content as
well as the activity of peroxidase and polyphenoloxidase in the leaves
and fruits increases and continues to do so until complete ripening
of fruits. After ripening, protein content and enzyme activities don't
change or slightly decrease until the harvest of fruits. The trend seems
to be similar in the "on" and "off" years, but in
the "off" years the protein content and enzyme activity in
the leaves and fruits are greater reflecting the various metabolic status
of the plant during floral induction and fruit ripening.
