Depending on the variety, the total surface areas of trees: all branches, boughs and tree trunks after winter pruning, ranged from 27 dm2 to 118 dm2. The development of stem and leaf surface areas were studied comparatively throughout a year’s cycle, and the proportions of these areas within the total area of trees were calculated. The species studied could be grouped according to their leaf pattern as brevideciduous or deciduous and according to their reproductive pattern as having long-term or short-term strategies. The foliation of the four species is phenologically related to the rainy season. macroprophyllata, which show a reproductive strategy associated with the rainy season. lutescens as species with a reproductive strategy (flowering and fruiting) synchronized with the dry months, in contrast to A. Phenological characteristics distinguish A. The phenology was correlated with the stages of rain and drought by Spearman’s correlations Variable time periods were adapted to the extended BBCH scale.
Stages of foliation, flowering, fruiting and senescence of 20 individuals per species were documented by written and photographic records during the course of a year. What are the the foliar and reproductive strategies of four species of Annona living in the Deciduous Forest of Chiapas, Mexico?Īnnona lutescens, A.
These studies provide useful means for understanding the relationships between plants and their environment. Phenological descriptions of plant species are used to understand cycles of foliation, flowering and fruiting.
