Popis: | 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. |
