Study on the Natural Regeneration of Quercus phillyraeoides Population in Different Communities

Abstract

Abstract: It is very important for regeneration of a population to maintain its stability and development.Based on the field investigation,the regeneration of Quercus phillyraeoides population in different places was discussed.The results are showed as fo11ows:(1)The pattern of population in most areas was shown with an inverted pyramid form,which means that there were difficulties for the population to regenerate;but in the climax community of Quercus phillyraeoides,the population regeneration could continue because of the number of young trees in a short period of time;(2)The spatial pattern of Quercus phillyraeoides seedling indicated that it was of an aggregated distribution in the canopy gaps or forest edge while even distribution existed under the crown of a tree,which means that there was a close relation to seedling growth and light.(3)The experiment of seed germination revealed that it was good for the seed to germinate through the way of sand storage for 1-2 months,and the rodent damage and moth attack was the key reason to restrict the rate of germination.(4)The seed dispersal of Quercus phillyraeoides was not only the gravity but also the rodent,and the latter had more influence on it in the forest communities.There was a trade-off relationship between the rodent and seed dispersal.To improve the natural regeneration of Quercus phillyraeoides,it was an effective measure to keep the canopy gaps in its forest.

Key words: Quercus phillyraeoides, population, regeneration, seedling
