Morphology and anatomy of developing fruits and seeds of Mammea americana L. (Clusiaceae) BJB
MOURÃO,K. S. M.; BELTRATI,C. M..
Morphological, structural and developmental features of fruits and seeds of Mammea americana L. are here studied, with the purpose to give a proper classification of their fruit and embryo type and to contribute to future taxonomical and ecological studies. The fruit is a berry and the "rind" consists of the exocarp, represented by a periderm with lenticels, and by the parenchymatic mesocarp, with branched secretory ducts and vascular bundles. The edible pulpy is formed by the endocarp, destituted of secretory ducts, and derived from the activity of a ventral meristem, which emerges early in the fruit development. The inner endocarp cell layers undergo a radial elongation and become firmly attached to the testal outer layers. At maturation the endocarp may...

Morphology and anatomy of developing fruits and seeds of Vismia guianensis (Aubl.) Choisy (Clusiaceae) BJB
MOURÃO,K. S. M.; BELTRATI,C. M..
Morphological, structural and developmental features of fruits and seeds of Vismia guianensis (Aubl.) Choisy. are here presented, with the purpose to elucidate their structure and to contribute to taxonomical and ecological studies of the family. The fruit is a berry and the "rind" is constituted by the exocarp and by the subepidermal layers which constitute the mesocarp. The reddish pulp, rich in starch, is constituted by the parenchymatic mesocarp, with branched secretory ducts and vascular bundles, joined with the endocarp, which arises from a ventral meristem. The bitegmic, anatropous ovules, provided by the endothelium, develop into anatropous, bitegmic and exalbuminous seeds. The reddish uniseriate testa shows phenolic contents. The tegmen becomes...

Growth and Yield Response of Watermelon to in-row Plant Spacings and Mycorrhiza Chilean J. Agric. Res.
Ban,Dean; Goreta Ban,Smiljana; Oplanic,Milan; Horvat,Josipa; Novak,Bruno; Zanic,Katja; Znidarcic,Dragan.
Worldwide, a significant increase in watermelon (Citrullus lanatus [Thunb.] Matsum. & Nakai) growing areas has been registered in the last few years. In-row plant spacing has a significant effect on the growth and yield of watermelon, and can enhance competition for water and nutrients. The aim of this study was to investigate the effects of in-row plant spacing (1.0, 1.5, 2.0 and 2.5 m) and arbuscular mycorrhiza (AM) fungi Glomus mosseae inoculations on watermelon growth and yield under field conditions during 2003, 2004, and 2005 year. In 2003, the main vine length, number of leaves, and number of lateral branches were increased quadratically as the in-row plant spacing increased from 1.0 to 2.5. With an increase in the in-row plant spacing the...

Distribution and recycling of canopy nitrogen storage reserves in sweet cherry (Prunus avium) fruiting branches following 15N-urea foliar applications after harvest Ciencia e Investigación Agraria
Ayala,Marlene; Bañados,Pilar; Thielemann,Mariana; Toro,Román.
In sweet cherries, accumulated nitrogen (N) stores from the previous fall support early spring growth. To complement the N supply in the soil, Chilean growers use foliar urea applications after harvest. Information on the effectiveness of foliar N applications in sweet cherry is lacking. To study the canopy distribution of N applied as urea foliar sprays, an experiment using a "Bing"/"Gisela®6" ("GI®6") sweet cherry orchard was carried out in 2009/2010 in Chile (35° 09' 53'' S, 71° 20' 43'' W). The objective was to investigate N distribution and recycling in 3-year-old fruiting branches. A total of 120 branches (one per tree) were labeled using 15N-urea. 15N-urea was applied to the whole branch on four separate dates or treatments (TR) after fruit harvest:...

Physicochemical and microbiological stability of mixed nectar of orange and uvaia Ciência Rural
Tomaz,Karla Silva; Ferreira,Mayara Rodrigues da Silva; Mesquita,Mércia da Silva; Oliveira Filho,José Humberto de.
ABSTRACT: The addition of Cerrado fruits to juice and nectar formulations is an interesting alternative for the beverage industry, as it allows developing innovative products containing nutritive and bioactive compounds. Thus, the objective of this study was to produce mixed nectar of orange and uvaia, using orange nectar as a control, and to evaluate physicochemical and microbiological characteristics of beverages during the storage. Mixed nectar formulations were prepared with the addition of uvaia pulp and orange juice, while the orange nectar was made with fruit juice, and the addition of mineral water and commercial sucrose. Resulting nectar was bottled in sterilized glass bottles, immediately closed and heat-treated in a water bath at 90 °C for 5...

Drying kinetics of bananas by natural convection: Influence of temperature, shape, blanching and cultivar Ciência e Agrotecnologia
Borges,Soraia Vilela; Mancini,Maurício C.; Corrêa,Jefferson Luiz Gomes; Leite,Julia Benedito.
The influence of variables as temperature, solid shape, temperature, branching and cultivar on drying of bananas were studied. Bananas from cv. Prata and D'água, on disk and cylindrical shape, blanched or not, were dehydrated in a tray dryer in natural convection at 40 and 70ºC. Drying behavior was analyzed by using a mathematical model. The exponential model showed good agreement to experimental data (r² 0.93 - 0.99 and standard error: 0.01- 0.05). Temperature presented positive influence on drying rate in all the tested conditions. With respect to the sample shape, the disk shape carried out to significantly higher drying rates only for D'água cultivar without blanching. Blanching was significantly influent, with positive influence, on drying rate of...
