چکیده

ABSTRACT The objective of this study was to evaluate the effects saline water irrigation management strategies and potassium doses on concentration photosynthetic pigments, gas exchange, fruit production ‘BRS GA1’ yellow passion fruit. experiment carried out under field conditions using a randomized block design, with treatments based 6 × 2 factorial scheme, related six for (irrigation low-salinity throughout crop cycle-WS; high-salinity in vegetative stage-VE; flowering stage-FL; fruiting stage-FR; successively vegetative/flowering stages-VE/FL vegetative/fruiting stages-VE/FR) two (60 100% recommendation), four replicates. dose recommendation corresponded 345 g K2O plant-1 year-1. High electrical conductivity (4.0 dS m-1) used different phenological stages according treatment, alternating low (1.3 m-1). synthesis chlorophyll b, stomatal conductance, instantaneous carboxylation efficiency use were reduced 4.0 m-1 all adopted. Fertilization 60% K promoted greater number fruits yield. Irrigation yield

Genetic diversity in yellow passion fruit populations

The genetic diversity in yellow passion fruit genotypes from populations of different origins (Campos dos Goytacazes, Itaperuna and São Francisco de Itabapoana , Rio de Janeiro State, Brazil), was quantified. The following traits were evaluated in two environments (Macaé and Campos dos Goytacazes): fruit weight, mean number of fruits, fruit length, equatorial fruit diameter, rind thickness, bri...

Detection of a resistance gradient to Passion fruit woodiness virus and selection of 'yellow' passion fruit plants under field conditions.

Productivity of 'yellow' passion fruit (Passiflora edulis Sims. f. flavicarpa O. Deg.) is reduced by infection with Cowpea aphid-borne mosaic virus (CABMV). We examined resistance in 72 yellow passion fruit plants grown from open-pollinated commercial seed. Plants were mechanically inoculated with CABMV virus and maintained in the field in order to select contrasting genotypes for resistance. I...
