Abstract
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 $7^{\circ}C$.
