ABSTRACT The objective of this study was to evaluate the physiological indices sour passion fruit under brackish water irrigation strategies and potassium fertilization. carried out field conditions in São Domingos, PB, Brazil, using a randomized block design 6 × 2 factorial scheme, with treatments consisting six (irrigation moderately saline (1.3 dS m-1) throughout crop cycle - WS; high-salini...

the possible alleviating effects of salicylic acid on protection of cowpea (vigna unguiculata) cv. parastu under water stress conditions were investigated in the university of zanjan agriculture research station during 2008. water stress was imposed by withholding irrigation at 50% flowering (flowering water stress, fws) and when 50% of the pods grew 2-3cm (pod-formation water stress, pfws). sa...

ETHNOPHARMACOLOGICAL RELEVANCE Different parts of Ocimum gratissimum Linn are largely used in folk medicine for the treatment of many diseases, some of which related to parasitical infections as fevers and headaches. In order to validate their use and to clarify the plant part which possesses the best antiparasitic properties, we decided to evaluate the in vitro antiplasmodial and antitrypanoso...

ABSTRACT This study was conducted with the objective of evaluating quantum yield, photosynthetic pigments and biomass accumulation mini watermelon cv. Sugar Baby, under strategies irrigation saline water potassium fertilization. The experiment in a randomized block design, 8 × 3 factorial scheme, three replicates, corresponding to eight applied at different phenological stages crop (control - l...

Here we analyzed in leaves the effect of FT overexpression driven by meristem-specific KNAT1 gene homolog of Arabidopsis thaliana (Lincoln et al., 1994; Long et al., 1996) on the transcriptomic response during plant development. Our results demonstrated that meristematic FT overexpression generates a phenotype with an early flowering independent of photoperiod when compared with wild type (WT) ...

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-sali...

This study was conducted to determine the chemical composition, metabolizable energy, digestibility and ability of gas production of Poa trivialis. Samples was collected at three phenological stages including: vegetative growth, flowering and seedling on two different elevations of 1300 to 1500 m and 2000 to 1800 m asl in Neor and Hir region as the first and second sites, respectively. Testing ...

Invasive species that are closely related to each other may have similar population dynamics and, therefore, be controlled by targeting life stages. We studied two invasive knapweed species, spotted (Centaurea stoebe subsp. micranthos) and the hybrid meadow complex ( Centaurea × moncktonii ) in New York, USA, determine their individual growth rates (λ) across several sites over three years. Bot...

The transcription factor HAHB10 belongs to the sunflower (Helianthus annuus) HD-Zip II subfamily and it has been previously associated with the induction of flowering. In this study it is shown that HAHB10 is expressed in sunflower leaves throughout the vegetative stage and in stamens during the reproductive stage. In short-day inductive conditions the expression of this gene is induced in shoo...
