    Cambial dormancy in a tropical evergreen species is long lasting, and the initiation of cambial activity is related to day length.
  • Abstract
    Studies on cambial activity allow us to understand the growth dynamics of plants. In this study, we investigate cambial activity and the conducting phloem in a population of an evergreen shrubby species from a semi-deciduous tropical forest with distinct wet and dry seasons. Stem samples from Cordiera concolor were collected bimonthly in 2010 and prepared according to the standard methods for plant anatomy. The relationship between cambial activity and climate factors as well as phenology was investigated using Spearman’s correlation. The cambium is dormant during the rainy season and dormancy lasted up to 9 months. Cambial activity was positively related to day length, and although it occurred in the rainy season, the period of its onset and termination was not concurrent with the beginning and end of the rainy season. The conducting phloem corresponded most to the non-collapsed phloem and was present year-round, ranging in width (in transverse section) from 62 µm in the rainy season to 112 µm in the dry season. Together, these results illustrate that cambial activity in an evergreen species of a seasonal tropical forest is seasonal with long-lasting cambial dormancy, and that at least some conducting phloem is present year-round.
