Abstract: Through the cuttage experiments of Liriodendron chinense L .tulipifera conducted in spring and summer , characteristics such as the time of adventitious root formation , the effect of terminal bud and the state of callus are studied in detail .The results show that the cutting in different seasons have different biological characters of root formation .The time of adventitious rooting formation is longer in spring (60 ~ 80 d) than in summer (20 ~ 30 d);the effect of termindal bud in summer is stronger than that in spring .When cuttage is conducted in spring , there are serious phenomena of pseudo-growth , the number of adventitious roots is 3 ~ 4 and smaller than that in summer ;when cuttage is conducted in summer , the cutting are likely to rot .When cuttage is conducted in spring , the number of adventitious roots is 3 ~ 4 ;when cuttage is conducted in summer , the number is over 10 . When cuttage is conducted in spring , the cuttings have few calluses ;when cuttage is conducted in summer , some cuttings have only calluses but no roots .Therefore , different measures of cuttage shall be taken in different seasons to improve rooting rate .[ Ch , 2 fig .1 tab .14 ref .]
