| Heart-of-palm, palm heart, or "palmito" can be considered as a non-conventional vegetable, largely consumed in Brazil and exported to more than sixty countries. Timing of heart-of-palm harvesting is a critical issue in palmito agribusiness, since it affects yield, quality and costs. A three-year field experiment was utilized to identify the correct timing for king palm heart-of-palm harvesting, from the standpoint of maximizing yield and minimizing growing period. The experimental site was located at Pariqueraçu, Vale do Ribeira, a region where palmito agribusiness has increased recently, due to adequate climatic conditions, low costs and high industry demand. Crop was grown in 2 x 0.75 m spacing, utilizing six-month old seedlings. Growth was assessed... |

| A determinação do coeficiente de caminhamento é bastante útil no melhoramento genético de plantas perenes. No presente estudo foram estimados os efeitos diretos e indiretos de cinco caracteres vegetativos da planta, relacionados ao crescimento, sobre os principais componentes da produção de palmito da palmeira real australiana (Archontophoenix alexandrae Wendl. & Drude), por meio do coeficiente de caminhamento. Para tanto, foram utilizados dados obtidos por ocasião da colheita realizada em 238 plantas de um experimento, com três de anos de campo, conduzido em Pariquera-Açu, SP. Desdobraram-se as correlações lineares simples existentes entre as variáveis padronizadas (dependentes e independentes), estabelecendo-se posteriormente um diagrama causal e... |

| Archontophoenix palms, utilized both as ornamental species and as a source of high-quality heart of palm, are susceptible to sooty mold, a disease coupled with aphid infestation, which affects photosynthesis and causes unpleasant, darkish palm appearance. Scoring rates for sooty mold resistance and three growth traits were assessed under field conditions in 24 open-pollinated half-sibs families, 28 months after planting, aiming to identify genetic variability for sooty mold resistance; estimate genetic parameters for this trait and plant height, diameter and number of leaves; estimate genetic and phenotypic correlation for the four traits and evaluate selection methods for heart of palm production through multi-trait index selection based on growth traits.... |
