Abstract Coconut palm (Cocos nucifera L.) is one of the most important tropical species used by man, known as “tree life”. In recent decades, with expansion coconut growing areas, limitations such occurrence pests, uniformity crops, adaptation to different ecosystems and others have affected production longevity trees. This review describes major advances in propagation techniques palm, conventionally, seeds through plant tissue culture from mid-twentieth century onwards, well phytosanitary...
In February of 2004, at "Platô de Neópolis", Sergipe, Brazil, about 50 coconut plants were found bearing symptoms a disease not yet recorded in Brazil.The trunk diseased exhibited reddish-brown or rust��colored liquid bleeding from scars.Inside the stem, tissues under lesions rotting and turned brownish-yellow to black.Diseased palms had reduced growth three four months after first noticed affected died.A fungus was isolated identified as Thielaviopsis paradoxa.Healthy inoculated with...
Despite the larger total amount of photosynthetic photon flux density (PPFD) in dry seasons, integrated values stomatal conductance (Gs), photosynthesis (A) and transpiration (E) were higher during wet season six tall genotypes Cocos nucifera L. Average A E from all correlated with PPFD (r2 = 0.711, p <0.001) but not Gs 0.301) season. Conversely, strongly 0.776, 0.169) Five showed strong reduction (between 46–86%) A, Contrastingly, Brazilian genotype (BRT) reduced only between 12–29% leaf...
Avaliou-se o curso diurno e sazonal do potencial hídrico das trocas gasosas foliares coqueiro-anão (Cocos nucifera L.) sob condições de campo, no município Ilha Flores-SE. As quatro variedades estudadas (Anão Vermelho Camarões - AVC, Anão Gramame AVG, Amarelo AAG Verde Jiqui AveJ) reduziram drasticamente a condutância estomática (gs) período seco. Sob estiagem, os valores transpiração (E) fotossíntese líquida (A) foram reduzidos principalmente nas AVG AVeJ, as quais apresentaram aumento...
SUMMARY Daily courses of leaf gas exchange and water potential (Ψ ) green dwarf coconut palm ( Cocos nucifera were measured in irrigated plantations on the wet coastal plateau a dry semi-arid area northeast Brazil. At both sites, significant correlations obtained between stomatal conductance (gs) vapour pressure deficit (VPD air ), Ψ VPD , transpiration (E) gs, E-Ψ . Despite these similar relationships stronger involving gs-VPD found at site, where whole-plant hydraulic (gp) was correlated...
The behavior of coconut (Cocos nucifera L.) stomata was studied under field conditions in adult plants. Hourly determination relative stomatal opening and conductance values revealed that were opened maximally between 0800 1600; by the end this period, closed rapidly as solar radiation decreased. Changes temperature humidity air did not affect behavior. maximum occurred at midday, when water potential leaf is its lowest point, showing depends mostly on does control loss efficiently stress.
A fenologia do coqueiro fornece informações que tornam possível a seleção de cultivares partir características permitam maior eficiência no uso ambiente, tornando seu comportamento previsível em diversas condições. Dessa forma, analisou-se coqueiro-anão nas condições edafoclimáticas dos tabuleiros costeiros norte Sergipe. O experimento foi conduzido um plantio comercial da empresa Agreste delineamento experimental blocos ao acaso, com quatro tratamentos e repetições, utilizando-se oito...
Avaliou-se o efeito do déficit hídrico e da irrigação com água de diferentes níveis salinidade, no desenvolvimento coqueiro (Cocos nucifera L.) "Gigante Brasil", cinco anos idade cultivado em condições campo. O experimento foi conduzido Campo Experimental Embrapa Tabuleiros Costeiros, localizado município Itaporanga D'Ajuda, SE. delineamento experimental utilizado blocos ao acaso, quatro tratamentos repetições. Cada parcela constituída 12 plantas úteis. Os foram: sem (T0), aplicação 40 L...
