Arbuscular mycorrhizal inoculation increases biomass of Euterpe edulis and Archontophoenix alexandrae after two years under field conditions Rev. Bras. Ciênc. Solo
Sgrott,Andressa Franzoi; Booz,Maristela R.; Pescador,Rosete; Heck,Teresinha Catarina; Stürmer,Sidney Luiz.
Inoculation with arbuscular mycorrhizal fungi (AMF) of tree seedlings in the nursery is a biotechnological strategy to improve growth, survival after transplanting, biomass production and to reduce the use of fertilizers. Archontophoenix alexandrae and Euterpe edulis are palm species used in southern Brazil to produce the palm heart, the latter being included in the list of threatened species due to the overexploitation of its native population. The purpose of this paper was to evaluate the effect of mycorrhizal inoculation on growth and physiological parameters of A. alexandrae and E. edulis. After germination, the seedlings were inoculated (AMF) or not (CTL) with AMF in the treatments. Values of chlorophyll content, biomass and shoot phosphorus were not...

Development and optimization of a HPLC-RI method for the determination of major sugars in apple juice and evaluation of the effect of the ripening stage Ciênc. Tecnol. Aliment.
Zielinski,Acácio Antonio Ferreira; Braga,Cíntia Maia; Demiate,Ivo Mottin; Beltrame,Flávio Luís; Nogueira,Alessandro; Wosiacki,Gilvan.
The sugars in apple juice prove its authenticity and its sensory and nutritional properties. The aim of this study was to develop and validate a simple analytical method using high performance liquid chromatography with refractive index detection (HPLC-RI) to determinate and quantify the sugars sucrose, D-glucose, D-fructose, and D-sorbitol polyol in apple juices, as well as to analyze the juices from the Fuji suprema and Lis Gala cultivars at three ripening stages. The analytical performance parameters evaluated indicated that the method was specific for the compounds analyzed, and the linearity of the calibration curves of sugars showed high correlation coefficients (close to 1.0). The limits of detection and quantification are consistent with...

Morphological and physiological adjustments of Brazilwood (Caesalpinia echinata Lam.) to direct solar radiation Braz. J. Plant Physiol.
Mengarda,Liana Hilda Golin; Milanez,Camilla Rozindo Dias; Silva,Diolina Moura; Aguilar,Marco Antonio Galeas; Cuzzuol,Geraldo Rogério Faustini.
This study aimed to characterize the alarm and resistance phases of stress of Caesalpinia echinata under intense irradiance in order to better define its position on forest succession. The alarm phase was identified by rapid reduction in the maximum quantum yield of PSII primary photochemical reactions (ΦP0 = FV/FM) and Performance Index (PIABS) followed by total leaf abscission in the first week of exposure to direct sunlight. The new leaves grown showed recovery of chlorophyll a parameters, increase in blade thickness, elongation of the palisade and spongy parenchymas, higher water content, and reduction of specific leaf area. These changes were associated with the osmoprotector of sucrose and antioxidative of raffinose effects, which indicate an...

Nitrógeno reducido, AG, y carbohidratos solubles en el amarre de frutos de aguacate (Persea americana Mill.) "Hass" Colegio de Postgraduados
Espíndola Barquera, María de la Cruz.
La investigación aquí reportada examina la relación entre el amarre de fruto de aguacate ‘Hass’ y las aplicaciones de N, AG3 y anillado, así como los cambios en el nitrógeno reducido, variables fotosintéticas, carbohidratos solubles, AG3, anormalidades florales y calidad de fruto. La investigación se realizó en la floración II durante el ciclo de baja (2003-2004 y 2005-2006) y alta producción (2004-2005). La aplicación de N realizada durante el crecimiento vegetativo I incrementó el amarre inicial de fruto, entre 168% y 207%, sólo en el primer año de evaluación (2003-2004). No hubo efecto en la acumulación de nitrógeno reducido, variables fotosintéticas, anormalidades florales y calidad de fruto. Los tratamientos aplicados en el estado ocho del desarrollo...

Solutos orgânicos em genótipos de sorgo forrageiro sob estresse salino. Repositório Alice
OLIVEIRA, L.A.A.; BARRETO, L.P.; BEZERRA NETO, E.; SANTOS, M.V.F. dos; COSTA, J. de C.A..
O objetivo deste trabalho foi verificar o acúmulo de solutos orgânicos, em materiais genéticos de sorgo sob estresse salino. O experimento foi realizado em casa de vegetação, em delineamento experimental inteiramente casualizado, organizado em arranjo fatorial entre três índices de salinidade no solo (2,4, 10 e 16 dS m-1) e dez genótipos de sorgo forrageiro (IPA SF-25, IPA 02-03-01, IPA 42-70-02, CSF-4, CSF-5, CSF-6, CSF-7, CSF-8, CSF-9 e CSF-10), com quatro repetições. Os índices de salinidade 10 e 16 dS m-1 incrementaram o teor de carboidratos solúveis totais em 20,2 e 21,3%, respectivamente. O teor de proteínas solúveis variou entre as cultivares de sorgo em resposta aos índices de salinidade do solo. Os maiores valores de aminoácidos livres totais...

Variations in sugars and cyclitols during development and maturation of seeds of brazilwood (Caesalpinia echinata Lam., Leguminosae) Braz. J. Plant Physiol.
Borges,Igor F.; Barbedo,Claudio J.; Richter,Andreas A.; Figueiredo-Ribeiro,Rita de Cássia L..
Seeds of Caesalpinia echinata are tolerant to desiccation, keeping their viability up to 0.08 g H2O g-1 DM. When stored under laboratory conditions they lose their viability within one month, while under low temperatures germination ability is maintained during two years of storage. Here, we report on the variations of soluble carbohydrates, cyclitols and cyclitol galactosides in seeds of C. echinata during development and maturation, aiming for a better understanding of the involvement of these compounds in the maturation process and seed quality. Individual flowers were tagged on the day of anthesis and pods were collected directly from the branches from 32 to 59 d after anthesis (DAA). Seeds were also collected after shedding. The physiological maturity...
