A regular pruning cycle (RPC) reduces costs when implementing crop treatments and facilitates semi-mechanized harvesting. However, there is information on plant development under this system. Thus, this study aimed to assess the new branch growth of 22 genotypes of Coffea canephora (conilon) after a regular pruning cycle. The assay was conducted at Cachoeiro de Itapemirim, Southern Espírito Santo State, Brazil. Measurements of 12 morphoagronomic traits were performed, and their relationships with temperature and rainfall were studied. The branch vegetative growth rates varied seasonally throughout the assessment period, with higher growth rates and higher temperatures, even not extreme, during rainy periods and lower growth rates and milder temperatures during the dry season. The logistic model with best fit to describe pattern of cumulative growth by genotypes following RPC was sigmoid for all the studied traits.
Key words: Coffea canephora, growth curve, seasonality, temperature.
