한국 자생 노랑붓꽃과 금붓꽃을 초봄의 분화로서의 가치를 구명하기 위하여 11 월 1일부터 12월1일까지 15일 간격으로 3차례 입실하였고, $7^{\circ}C$, $12^{\circ}C$와 $15^{\circ}C$의 온도 처리구에 12월1일에 입실시켜 개화 및 생육에 미치는 영향을 조사하였다. 노랑붓꽃과 금붓꽃은 입실시기가 지연될수록 초장이 커지고 엽수가 많아졌다. 노랑붓꽃을 11윌 1일에 입실한 것은 전혀 개화를 하지 않았으나 11윌 16일에 입실한 것은 30%를 개화하였고, 12윌1일에 입실한 것은 100% 개화하였다. 한편 금붓꽃은 11월1일부터 12월 1일 사이에 입실한 것 모두가 개화되었다. 개화주의 개화수와 개화기는 차이가 없었다. 한편 입실온도가 증가할수록 초장과 엽장이 작아지고 엽수가 현저히 많아졌다. 노랑붓꽃을 $12^{\circ}C$와 $15^{\circ}C$에 입실한 것은 전혀 개화를 하지 않았으나 $7^{\circ}C$에 입실한 것은 100% 개화하였다. 금붓꽃을 $15^{\circ}C$에 입실한 것은 전혀 개화를 하지 않았으나 $12^{\circ}C$에 입실한 것은 30% 개화하였고 $7^{\circ}C$에 입실한 것은 100% 개화하였으며 개화시기가 빠르고 화경 및 화경장이 길었다.

This experiment was conducted to investigate growth and flowering characteristics of Iris koreana and Iris minutoaurea Makino native to Korea for potting plant of early spring treated by forcing date and temperature. As forcing date delayed from November 1 to December 1, the plant height and number of leaves were increased, however no difference in the number of flower and date of flowering. In Iris koreana, the plant was not flowering in forcing on November 1, flowering 30% on November and 100% on December 1. However all the forcing plant flowered in Iris minutoaurea Makino. As forcing temperature increased from $7^{\circ}C$ to $15^{\circ}C$, the plant height and number of leaves were decreased, however the number of flower in $7^{\circ}C$ was increased and date of flowering was earlier than ones of higher temperature. In Iris koreana, the plant was not flowered in forcing $12^{\circ}C$ and $15^{\circ}C$, all flowered in forcing $7^{\circ}C$. Iris minutoaurea Makino was flowered 30% forcing in $12^{\circ}C$ and all flowered forcing in $7^{\circ}C$.
