| Abstract;The effect of growth temperature on lignotuber formation in Telopea speciosissima seedlings as well as the relationship with leaf shape was studied. 1) Six months after sowing, lignotuber started to form as a swelling at the cotyledonary nodes. Initially, They began in an orthogonal arrangement at the opposite cotyledons, and then stem tissue above the cotyledons swelled succeedingly. The vegetative bud primordia were formed over the surface and some of them elongated into shoots. 2) When plants grown at 25.DEG.C. and under low land conditions, which experienced temperatures above 25.DEG.C., lignotuber formation and development was depressed. Several seedlings did not form lignotuber and shoots borne from axillary buds in the basal nodes. While at 20.DEG.C., 25/15.DEG.C., 15.DEG.C. and high land cultivation treatments, all plants formed lignotuber. The temperature condition suitable for lignotuber enlargement was 20.DEG.C.. 3) Despite evident variations in leaf shape, no significant correlations between leaf shape categories and lignotuber formation rate were encountered.
