“…A limiting factor for the production of this fruit crop in the semi-arid region of northeastern Brazil is the occurrence of low rainfall, temporal and spatial variability, and high temperatures and evapotranspiration (LIMA et al, 2016;SANTOS et al, 2016). In this region, water scarcity makes it impossible to grow fruit crops under a rainfed regime (SILVA et al, 2016), so irrigation becomes necessary. However, the occurrence of water sources with high concentrations of salts is a barrier to the expansion of irrigated agriculture (BEZERRA et al, 2018).…”

Sour passion fruit is a fruit crop widely cultivated throughout Brazil, due to its adaptation to the tropical climate. However, in semi-arid regions its development is limited by the high concentration of soluble salts in the waters commonly used in irrigation. In this context, exogenous application of low concentrations of hydrogen peroxide can attenuate the damage caused by salt stress. The objective of this study was to evaluate electrolyte leakage, photosynthetic pigments and photochemical efficiency in sour passion fruit cv. BRS Rubi do Cerrado under irrigation with saline waters and foliar application of hydrogen peroxide. A completely randomized design was used, with treatments arranged in split plots, corresponding to five levels of irrigation water salinity - ECw (0.6; 1.2; 1.8; 2.4 and 3.0 dS m−1) and four concentrations of hydrogen peroxide - H2O2 (0; 15; 30 and 45 μM of H2O2) in plots and subplots, respectively. Irrigation with saline water reduced chlorophyll a and total chlorophyll contents of sour passion fruit plants cv. BRS Rubi do Cerrado, at 240 days after transplanting. Hydrogen peroxide at concentration of 15 μM stimulated chlorophyll a and total chlorophyll biosynthesis and, at 45 μM, relieved the effect of 3.0 dS m−1 water salinity on electrolyte leakage in the leaf blade of sour passion fruit. Salt stress did not affect the initial, maximum, variable fluorescence and quantum efficiency of photosystem II of sour passion fruit cv. BRS Rubi do Cerrado.

“…There was difference of 31% in income values between the lowest and highest irrigation levels ( Figure 4D). This results are above 50% yield required by the processed market, with fruits suitable for consumption in natura and for industry (Chagas et al, 2016;Silva et al, 2016a). However, this increase in pulp yield may be related to the reduction in peel thickness occurred with water replacement rates above 100% of ETo.…”

“…Although there are publications on the passion fruit cultivation under irrigated system (Cavichioli et al, 2008;Nascimento et al, 2015;Silva et al, 2016a), it is necessary to obtain information to enable understanding the daily seasonal variability of the fluorescence of chlorophyll a according to irrigation management, which helps identify water replacement levels that affect the photosynthetic apparatus and consequently the fruit characteristics. This study was developed in order to analyze the photochemical and productive performance of the passion fruit hybrid 'BRS Gigante Amarelo' irrigated in the Brazilian Semiarid.…”

The drought stress is an important factor for crops in areas with low rainfall as in the semiarid regions and affects immediately the physiological processes and plant production. However, irrigation is an essential practice to minimize effects of drought stress since the appropriate management is done it can increase the farm income. This study aimed to analyze the photochemical and productive performance of passion fruit (Passiflora edulis) hybrid 'BRS Gigante Amarelo' irrigated in a Brazilian semiarid region. It was studied four water replacement rates (33, 66, 100 and 133% of ETo) at field conditions. A randomized block design was used with five replications and the fluorescence of chlorophyll a, yield and fruit quality were evaluated. The photochemical efficiency of photosystem II has been changed along the day at high temperatures occurring evidential damage in PHS II. Water replacement between 100 and 133% of ETo (1032 mm year-1) promoted the best production rates and quality of the fruit, however the size of the fruit and bark thickness are reduced by over 100% ETo.

The study aimed to evaluate the mitigating effect of nitrogen (N) on the damages caused by irrigation water salinity, in the production of yellow passion fruit seedlings. A randomized block design in split plots was used, with five levels of irrigation water salinity (plot) (0.3, 1.0, 1.7, 2.4 and 3.1 dS m-1) and five doses of N fertilization (sub-plot) (180, 240, 300, 360 and 420 mg of N dm-3), with five replicates, totaling 125 experimental units, with one plant per plot. The seedlings were produced in 3.780 mL tubes, used as drainage lysimeter, which received a daily irrigation depth based on water balance. Growth and contents of chlorophyll and carotenoids were evaluated at 85 days after sowing. The increase in irrigation water salinity reduced stem diameter, plant height, number of leaves, chlorophyll a, chlorophyll b and total chlorophyll; increasing N doses also led to linear decline in stem diameter and plant height. Application of increasing doses of N did not attenuate the effect of salinity on growth and pigment contents.
