Abstract:

In order to understand spring bud dynamic of Taxus yunnanensis and the influencing factors, we investigated the living and dead numbers of spring buds at February, April and June. The results showed that the spring bud number of T. yunnanensis ranged from 3 to 29 per each individual, and the coefficient of variation was 42.93%. The number and density of spring buds in the upper crown was greater and higher than those in the lower crown. The spring bud number in the east of crown was smaller than that in the west of crown, while the spring bud density in the east of crown was lower than in the north of crown. The number of spring buds was highest in February. Likewise, dead spring buds and mortality were also most and highest in February and declined with time. The correlation analysis indicated the twig size and leaf number affected spring bud number. Basal diameter, top diameter and length of twig and leaf number were positively related to spring bud number.

Key words: spring bud numbers, temporal dynamic, spring bud density, correlation analysis, Taxus yunnanensis
