Abstract:
The winged-seeds of Keteleeria evelyniana spread by wind.To reveal the adaptability of seeds dispersal,the morphological characters of the seeds (weight,length,width,etc.) and its dispersal characters (proportion of the seed's wing,dropping time in the still air,etc.) were measured.The results showed:(1) Morphological characters were normally distributed,the weight and the length of the seeds and seeds' wings were positive correlated significantly;(2) Dropping time in the still air was affected comprehensively by the seed characters;(3) Morphological variation of the seeds was important to the seeds dispersal and population propagation in Keteleeria evelyniana Mast.
