Abstract: Resources are evenly allocated between reproductive and vegetative growth for Liriodendron chinense.Moreover,resource niches for reproductive vs vegetative structure developing are temporally overlapping.The patterns of reproductive package and resource allocation imply that large seeds are slightly advantageous over small ones.Resources seem to be partly partitioned to improve seed dispersal fitness.The hypothesis of resource limitation to seed-set does not occur in the species.The following life-history traits were recognized for L.chinense:(1)Possessing a high age of first fecundity(more than 10 years old);(2)Reproducing annually;(3)Reproducing in large quantity;(4)Possessing medial seeds;(5)Surviving for more than 100 years;(6) Maintaining a long stage of sexual reproduction.All these life-history traits suggest that L.chinense is a species with r-strategy.
