본연구(本硏究)는 생장(生長)이 우수(優秀)하여 선발(選拔)한 ${\times}$P. albaglandulosa 15 clone의 엽(葉)에 대(對)하여 과산화동위효소변이(過酸化同位酵素變異)를 전기영동법(電氣泳動法)에 의(依)거 조사(調査)하여 다음과 같은 결과(結果)를 얻었다. 15 clone의 총(總) band수(數)는 6~11본(本)이다. 그중(中) 활성(活性) band수(數)는 4~7본(本)이고 흔적(痕迹) band는 1~4본(本)으로서 어느 clone에서나 활성(活性) band가 다수(多數)히 출현(出現)하였다. 그리고 cathode측(側)은 anode보다 band의 출현(出現)이 어느 clone에서도 단조(單調)로웠다. 한편(便) 효소형(酵素型)이 각(各) clone마다 특이(特異)하여 clone시별(識別)을 가능(可能)케 하였으며 g와 1 band는 ${\times}$P. albaglandulosa의 고정(固定) band이다. 또한 ${\times}$P. albaglandulosa가 $F_1$인 까닭에 효소형(酵素型)의 유전적(遺傳的) 변이(變異)가 인정(認定)되었다.
The variation of isoperoxidase band patterns in the zymograms in the leaves of ${\times}$P. albaglandulosa clones showing excellent growth were observed by starch gel electrophoresis in this study. The results are summerized as follows; The numbers of total bands in the clones were six to eleven. Four to seven were active and one to four were of trace in these bands, and also active bands appeared plentifully in all clones. The appearing pattern of the bands was more monotonous to the cathode than to the anode. Besides, the uniqueness of the isoenzyme forms in each clone made possible to identify the clones, and g and 1 bands were fixed in ${\times}$P. albaglandulosa, ${\times}$P. albaglandulosa being $F_1$ hybrid, the genetic variation of isoenzyme forms was significant statistically.
