FLOWERING AND FRUITING PHENOLOGIES OF THE WOODY PLANTS IN THREE FLORAS IN CHINA
几个气候区木本植物的开花结果物候

Flowering and fruiting phenologies, and fruit and seed dimensions were analysedfor the woody plants in the floras of Hainan -Guangdong , Qinling and North-east China.Similar seasonal patterns of flowering and fruiting phenologies were found among thewoody floras, although the flora at lower latitude had longer flowering and fruitingperiods in the year, and had a peak of flowering appearing earlier and a peak of fruitingappearing later than the flora at higher latitude. Frequency distributions of fruit and seedsizes also showed similar patterns, although the range of fruit and seed dimensions becamenarrower with the increase of latitude. The smallest dimension of fruit (0.1 cm) was similaramong the floras, but the smallest dimension of seed became bigger with the increaseof latitude. Relationships between the flowering and fruiting phenologies and the airtemperature and rainfall were different among the floras .More obving correlation was found between the fruit ripening and the climate factors than between fruiting phenologyand the climate factors for the common woody plants in Dinghushan Biosphere Reserve ,Guangdong Province.
