“…Evaluating the effects of salt stress on the West Indian cherry cv. 'BRS 366 Jaburu', Dias et al (2019) found that the increase in water salinity from 0.8 to 3.8 dS m -1 caused reduction in the CO 2 assimilation rate of 49.13% (3.53 μmol m -2 s -1 ).…”

The objective of this study was to evaluate the gas exchange, chloroplast pigments and growth of ‘BRS Rubi do Cerrado’ passion fruit as a function of irrigation with saline water and potassium fertilization in the seedling formation stage. The experiment was conducted under greenhouse conditions in the municipality of Pombal-PB, Brazil. A randomized block design was used in 5 x 2 factorial scheme, corresponding to five levels of water electrical conductivity - ECw (0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1) and two doses of potassium - KD (50 and 100% of the recommendation), with four replicates and two plants per plot. Water salinity from 0.3 dS m-1 reduced the stomatal opening, transpiration, CO2 assimilation and inhibited the growth of ‘BRS Rubi do Cerrado’ passion fruit plants, at 40 days after sowing. There was no CO2 restriction in the substomatal cavity of passion fruit plants grown under water salinity from 0.3 dS m-1. Potassium dose of 150 mg kg-1 of soil, corresponding to 100%, intensified the effect of salt stress on the assimilation rate and instantaneous carboxylation efficiency in 'BRS Rubi do Cerrado' passion fruit. There was interaction between water salinity levels and potassium doses for the chlorophyll a and b contents of 'BRS Rubi do Cerrado' passion fruit.

“…In order to enable the use of these resources in agriculture, potassium fertilization should also be considered as an alternative that can minimize salt stress in plants (ABBASI et al, 2016). Potassium stands out as attenuator of the deleterious effects of water salinity on crops (GURGEL;GHEYI;OLIVEIRA, 2010;PRAZERES et al, 2015;LIMA et al, 2018;DIAS et al, 2019). Potassium participates in protein synthesis, carbohydrate metabolism and as an enzymatic activator.…”

The objective of this study was to evaluate the gas exchange, growth and production of yellow passion fruit cv. BRS GA1, as a function of irrigation management strategies with saline water and potassium doses. The experiment was conducted under field conditions in São Domingos, PB, Brazil. A randomized block design was used in a 6 * 2 factorial scheme. The treatments consisted of six strategies of irrigation with saline waters (irrigation with low-salinity water throughout the crop cycle - SE; irrigation with high-salinity water in the vegetative stage - VE; flowering stage - FL; fruiting stage - FR; in the successive vegetative/flowering stages - VE/FL; vegetative/fruiting stages - VE/FR) and two doses of potassium (100 and 130% of the K2O recommendation), with four replicates and four plants per plot. The 100% dose corresponded to 60 g of K 2O plant-1 year-1. The effects of using high-salinity water (3.2 dS m-1) alternated with low-salinity water (1.3 dS m-1) were evaluated in different stages of the cultivation cycle. Irrigation with saline water in the fruiting stage promoted an increase in intercellular CO2 concentration and decrease in CO2 assimilation, with effects of non-stomatal origin standing out as limiting factors of photosynthetic efficiency. The highest CO 2 assimilation rate in plants subjected to water salinity of 1.3 dS m-1 throughout the cycle resulted in increments in the number of fruits and in the production per plant of the passion fruit cv. BRS GA1.

“…Silva et al, 2016), in addition to protecting chlorophyll from photooxidation (Taiz et al, 2017). Corroborating these results, Dias et al (2019) found a reduction of 57.2% in the leaf content of carotenoids as water salinity increased from 0.8 to 3.0 dS m -1 in West Indian cherry cv. BRS 366 Jaburu.…”

“…Thus, it is clear that, under high salinity levels, the supply of 45/45% of K 2 O/P 2 O 5 had mitigating action on chlorophyll a synthesis, possibly because the increase in the supply of mineral fertilizers contributes to the increase in soil EC, given their salt indices, especially that of potassium chloride, compromising chlorophyll biosynthesis by crops. This situation has been observed in cowpea (Prazeres et al, 2015), colored cotton (A. R. Silva et al, 2017), and West Indian cherry (Dias et al, 2019) under water salinity conditions.…”

The objective of this study was to evaluate chloroplast pigments and photochemical efficiency of West Indian cherry cv. BRS 366 Jaburu as a function of irrigation water salinity and potassium-phosphorus fertilization combinations in the second year of cultivation. The experiment was carried out in a protected environment in Campina Grande, Brazil. Treatments were distributed in randomized blocks, in a 5 × 4 factorial scheme, corresponding to five levels of electrical conductivity of irrigation water ECw (0.6, 1.4, 2.2, 3.0 and 3.8 dS m-1) and four combinations of potassium-phosphorus fertilization (100/100, 85/85, 60/60 and 45/45% of the K2O/P2O5 recommendation for the second year of cultivation 200 g of K2O and 120 g of P2O5 per plant per year) with three replicates. Irrigation with saline waters hampered the biosynthesis of chloroplast pigments and the photochemical efficiency of West Indian cherry cv. BRS 366 Jaburu in the second year of cultivation. Water salinity from 2.6 dS m-1 reduced the maximum fluorescence, variable fluorescence, and quantum efficiency of photosystem II of West Indian cherry plants cv. BRS 366 Jaburu. Fertilization with 60/60 and 85/85% of the K2O/P2O5 recommendation promotes an increase in the synthesis of chlorophylls a and b, respectively, in the first and second production cycles of the second year of cultivation. Supply of 85/85% of the K2O/P2O5 recommendation promoted an increase in maximum and variable fluorescence in plants subjected to water salinities of 0.6, 2.2, and 3.8 dS m-1 in the second cycle and reduced the initial fluorescence, regardless of the salinity level in the first and second production cycles of West Indian cherry.
