“…The observed Fo value is lower than the range of 949.35 to 672.56 reported by Diniz et al (2021) for seedlings of yellow passion fruit cv. 'Gigante Amarelo' irrigated with saline water (3.1 dS m -1 ), but higher than the values found by Andrade et al ( 2022) for yellow passion fruit accession 'Guinezinho' irrigated with water up to 2.8 dS m -1 (121.84 to 146.77).…”

The Northeast region of Brazil is the primary producer of yellow passion fruit. In recent years, water scarcity has led passion fruit growers to use highly saline water for cultivation. Therefore, implementing technologies that alleviate the negative effects of salt stress on plants is a promising approach, particularly in semi-arid conditions. This study aimed to assess the efficacy of organomineral fertilizers in mitigating salt stress effects on chlorophyll-a fluorescence and gas exchange in ‘Guinezinho’ yellow passion fruit seedlings. The treatments were arranged in randomized blocks with four replicates and four seedlings per plot, following a 2 × 3 factorial design. The factors considered were irrigation using water with low (0.18 dS m-1) and high (4.0 dS m-1) electrical conductivity and three liquid organomineral attenuators (Codasal™, Aminoagro Raiz™, and a mixture of Codasal™ + Aminoagro Raiz™ at a 1:1 v/v ratio), applied through fertigation. Irrigation with water containing 4.0 dS m-1 electrical conductivity, combined with liquid fertilizers, resulted in increased substrate salinity, and reduced stomatal conductance in yellow passion fruit seedlings, particularly when Codasal™ was applied. Application of Codasal™ alone or in combination with Aminoagro Raiz™ significantly enhanced variable fluorescence, quantum efficiency of PSII, CO2 assimilation rate, and instantaneous carboxylation efficiency in ‘Guinezinho’ yellow passion fruit seedlings.

Paclobutrazol as a strategy to induce reproductive precocity in sour passion fruit

The adoption of growth regulators can be an alternative method to modulate the quality of the propagation material and obtain reproductive precocity. The objective was to evaluate if a gibberellin biosynthesis inhibitor affects the morphophysiological, biochemical and anatomical parameters of sour passion fruit seedlings and if such alterations affect the reproductive period. Two trials were conducted. In trial I, 40 days after emergence, the seedlings were immersed up to the substrate level in paclobutrazol (PBZ) solutions at concentrations of: 0, 40, 80, 120 and 160 mg L-1. At 45 days after the application of PBZ - DAA, the morphophysiology, biochemistry and anatomy were evaluated. Trail II was conducted in pots, using seedlings from trail I with 45 DAA of PBZ. At 200 days after transplanting, accumulation of shoots and roots fresh and dry mass (g), flowering speed index, total number of reproductive organs and SPAD index were evaluated. In seedlings, restriction of shoot growth induced by PBZ was associated with root increment, seedling quality, photosynthetic pigments and optimization of gas exchange. A shorter period of transition from the juvenile – vegetative phase to reproductive is observed when the seedlings were submitted to PBZ concentrations.

Salicylic acid is a phytohormone that has been used to mitigate the effects of saline stress on plants. In this context, the objective was to evaluate the effect of salicylic acid as a salt stress attenuator on the physiology and growth of precocious-dwarf cashew plants in the post-grafting phase. The study was carried out in a plant nursery using a randomized block design in a 5 × 4 factorial arrangement corresponding to five electrical conductivity levels of irrigation water (0.4, 1.2, 2.0, 2.8, and 3.6 dS m−1) and four salicylic acid concentrations (0, 1.0, 2.0, and 3.0 mM), with three replications. Irrigation water with electrical conductivity levels above 0.4 dS m−1 negatively affected the relative water content in the leaf blade, photosynthetic pigments, the fluorescence of chlorophyll a, and plant growth and increased electrolyte leakage in the leaf blade of precocious-dwarf cashew plants in the absence of salicylic acid. It was verified through the regression analysis that salicylic acid at a concentration of 1.1 mM attenuated the effects of salt stress on the relative water content and electrolyte leakage in the leaf blade, while the concentration of 1.7 mM increased the synthesis of photosynthetic pigments in precocious-dwarf cashew plants.
