Densidade radicular de progênies de pupunheira em função de adubação NPK
Provedor de dados: 75
Autores: Bovi,Marilene L. A.; Spiering,Sandra H.; Barbosa,Antonia Marlene M.
O uso eficiente de fertilizantes requer o conhecimento de seus efeitos tanto na biomassa aérea quanto na radicular, permitindo que se identifique uma adubação adequada do ponto de vista de uma melhor partição entre ambas. A massa de raízes secas por volume de solo vem sendo utilizada, principalmente em espécies perenes, como subsídio para estimativas de biomassa radicular. Com esse objetivo, foram estudados os efeitos da adubação NPK na densidade radicular de três progênies de pupunheira (Bactris gasipaes Kunth), cultivadas em um Aluvial álico (corrigido por meio de calagem) em Ubatuba, SP (clima "Cfa"), durante o ano de 1993. O delineamento foi um fatorial fracionado, composto por quatro doses crescentes de nitrogênio (0 a 400 kg/ha/ano de N), fósforo (0...

Adequate timing for heart-of-palm harvesting in King palm
Provedor de dados: 75
Autores: Bovi,Marilene L.A.; Saes,Luiz Alberto; Uzzo,Roberta Pierry; Spiering,Sandra H.
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...

Genetic parameters estimation in King palm through a mixed mating system model
Provedor de dados: 75
Autores: Bovi,Marilene L. A.; Resende,Marcos Deon V. de; Spiering,Sandra H.
Overestimation of the genetic parameters is common in palms due to the occurrence of geitonogamy and the absence of self-incompatibility mechanisms. Data from nursery grown Archontophoenix palms were utilized, assuming a mixed mating system including random cross-pollination and selfing at different rates. The objective was to show the importance of knowing the mating system predominant and define breeding strategies for that genus. Twenty-four King palm half sib families were evaluated at nursery conditions using a randomised complete block design, with nine replications and eleven plants per plot. Ten months after sowing, traits such as diameter, height, number of green leaves and length of the leaf sheath of the second leaf, were individually measured....
