Zusammenfassung
Es wurde die Aktivität von verschiedenenp-Nitrophenyl-d-glycosidasen während der Entwicklung und Reifung der Oliven in drei Jahren (1987–88; 1988–89, 1989–90) untersucht. Es wurde keine Aktivität in der voll entwickelten Frucht festgestellt. Es wurden die Aktivitätenα-Galactosidase,β-Galactosidase,α-Mannosidase,α-Arabinosidase undα-Xylosidase entdeckt und ihre Molekularmassen durch Gelfiltration-Chromatographie mit Sephadex G-100 bestimmt. Es gibt eine zeitliche Wechselwirkung zwischen der enzymatischen Aktivität und der Abnahme in der Zuckerzusammensetzung in dem Nichtcellulose-Anteil der Zellwand.
Summary
We have studied the activity of variousp-nitrophenyl-d-glycosidases during development and ripening of olive fruit in three seasons (1987–88, 1988–89, 1989–90). Activity was absent in the first phases of ripening but appeared in the completely developed fruit,α-Galactosidase,β-galactosidase,α-mannosidase,α-arabinosidase, andα-xylosidase activities were detected and their relative molecular mass determined by gel filtration chromatography using Sephadex G-100. There is a temporal correlation between enzymatic activity and decrease in non-cellulosic cell-wall neutral sugar composition.
