چکیده

ABSTRACT In the Brazilian semiarid region, occurrence of water sources with high salt concentrations stands out as a limiting factor for production most crops under irrigated conditions. This research was conducted to evaluate physical and chemical quality sour passion fruit function brackish irrigation strategies potassium doses. The experiment carried field conditions using randomized block design in 6 × 2 factorial scheme, consisting six (irrigation 1.3 dS m-1 throughout cycle - WS; 4.0 vegetative stage VE; flowering FL; fruiting FR; successive vegetative/flowering stages VE/FL; vegetative/fruiting VE/FR) two doses: 60 100% (345 g K2O per plant year) recommendation, four replicates three plants plot. Irrigation or continuously reduced yield size fruit. Fertilization 60% K is recommended fruits greater polar diameter. It feasible cultivate fertilization recommendation without losses ascorbic acid total soluble sugars.

Histological analysis of pollen-pistil interactions in sour passion fruit plants (Passiflora edulis Sims).

The success of sexual plant reproduction is directly influenced by specific interactions between the pollen and pistil. Light, fluorescence and scanning electron microscopy techniques were used to evaluate the steps of pollination in sour passion fruit plants (Passiflora edulis Sims). In the compatible interaction, pollen tubes grow through stigma projections towards the ovary. The pollen grain...

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...
