Antioxidative enzymes during germination of two lines of Serbian spruce [picea omorika (panc.) purkyae]

Abstract

dTwo lines of Picea omorika (Pane.) Purkyne were compared with respect to germination percentage as well as specific activity and isoenzyme pattern of catalase, superoxide dismutase, and peroxidase (POD) during germination. Line A had a higher gennination percentage and higher enzyme activities in dry seeds and seedlings compared to line C. Peroxidase activity was not detected in dry seeds, but measured up to 10 U/g and 28 U/g on the 7(th) day of germination in lines C and A, respectively. The most abundant POD basic isoform in seedlings of both lines (pl 8.2) was not found previously in needles of adult Serbian spruce trees of the same lines.

Poređeni su procenat klijanja, specifična aktivnost i izoenzimski profil katalaze, superoksid dismutaze i peroksidaze u dve linije omorike [Picea omorika (Panč.) Purkyně] u toku klijanja. Linija A je imala veći procenat klijanja i veće enzimske aktivnosti u suvom semenu i klijancima, u poređenju sa linijom C. Peroksidazna aktivnost nije nađena u suvim semenima, a povećavala se do 10 U/g i 28 U/g sed- mog dana klijanja u linijama C i A, respektivno. Najzastupljenija bazna izoforma peroksidaze u klijancima obe linije (pI 8.2) nije nađena ranije u četinama odraslih jedinki istih linija. .
