Com o objetivo de caracterizar a acumulação de matéria seca pelo cafeeiro conilon (Coffea canephora Pierre), um experimento foi conduzido em Marilândia/ES, no delineamento de blocos casualizados, com 24 tratamentos (época de amostragem) e três repetições. Utilizou-se a variedade clonal EMCAPA 8111, plantada em outubro de 1995. Constatouse que o cafeeiro conilon apresentou padrão sigmoidal de crescimento até os seis anos de idade, com acumulação crescente de massa de matéria seca. Houve declínio na taxa de crescimento absoluto após 48 meses de idade e diminuição na taxa de crescimento relativo após o primeiro mês de idade.
The objective of this study was to characterize the dry matter accumulation of Conilon (Coffea canephora Pierre) coffee plants. The experiment was conducted in Marilândia/ES, Brazil, in an orchard with the clone 02, from the clonal variety EMCAPA 8111, established in October 1995. The experiment was arranged in a randomized block design, with twenty-four treatments (date of sampling) and three repetitions. It was found that up to six years of cultivation, plants of Conilon coffee show a sigmoid growth pattern, with a continuous increase in dry matter accumulation. There was a decline in the absolute growth rate after 48 months of cultivation, whereas for the relative growth rate, the reductions were observed after only one month of cultivation. |

The economics of coffee plantations is intrinsically linked to pruning, which can improve the canopy architecture and thereby increase productivity. However, recommended pruning times on conilon coffee plantations have been made on an entirely empirical basis. In this study, by evaluating growth, photosynthetic gas exchanges, starch accumulation and crop productivity, the effects of pruning at different times between harvest and flowering were investigated for six conilon coffee clones with distinct stages of fruit maturation (early, intermediate and late). Clones with an early maturation stage were pruned at four different times: 0, 30, 60 and 90 days after harvest (DAH). Intermediate clones were pruned at 0, 30 and 60 DAH, and late clones were pruned at 0 and 30 DAH. Overall, the rates of shoot growth and net photosynthesis, the stomatal conductance and the crop yield were not affected by the pruning treatments in any of the clones. In addition, pruning times did not affect the concentrations of starch or the photochemical efficiency of photosystem II. The carbon isotope composition ratio was marginally affected by the treatments. These results suggest that the pruning time after harvests is relatively unimportant and pruning operations can be scheduled to optimise the use of labour, which directly impacts the production costs of coffee. |
