Abstract

With polyacrylamide gel electrophoresis, peroxidase isoenzyme patterns in the terminal buds of grafted, 20-year-old Pinus elliottii trees were compared between abundant-flowering and poor-flowering trees during the period of female flower bud initiation. A total of nine peroxidase bands were observed in the terminal buds. The total amount of peroxidase enzymes in slash pine buds showed no significant difference between the abundant-flowering and poor-flowering trees. However, the fifth band from the gel front was observed in all the samples of abundant-flowering trees throughout the sampling period (July 8 to September 17), while this band was absent in most of the poor-flowering trees.

Polyacrylamide gel 전기영동법(電気泳動法)을 이용(利用)하여, 슬래쉬 소나무 (접목묘(接木苗), 20년생(年生))의 화아원기형성기간(花芽原基形成期間) 동안에 자화다량(雌花多量) 개화개체(開花個体)와 소량(少量) 개화개체간(開花個体間)에 정아(頂芽)의 peroxidase 동위효소(同位酵素)의 변화(変化)를 비교(比較)하였다. 정아(頂芽)에서 모두 9개의 band를 관측(観察)할 수 있었으며, 두 개체간(個体間)에 동위효소(同位酵素)의 양적(量的)인 차이(差異)는 미세(溦細)하였으나, 제오(第五) band는 다량(多量) 개화개체(開花個体)에서 대부분(大部分) 발견(発見)되었다. 제오(第五) band의 동위효소(同位酵素)는 자화원기형성(雌花原基形成)에 직접(直接) 관병(関聠)되는 것 같이 생각된다.
