To date, ‘Japansche Citroen’ (JC) has only been used commercially as a rootstock in Indonesia; however, the use of suitable rootstock remains challenging because of water limits in different places. The morphological, physiological, and gene expression changes of one-and-a-half-year-old mandarin cv. ‘Keprok Batu 55’ (KB) and sweet orange cv. ‘Manis Pacitan’ (MP) budded onto ‘Japansche citroen’ (JC), ‘Rough Lemon’ (RL), ‘Salam’ (S), ‘Volkameriana’ (V), and ‘Cleopatra Mandarin’ (C) rootstocks, subjected to six-week drought-stress conditions, were examined...

Hort. Sci. (Prague), 2024, 51(4):270-277 | DOI: 10.17221/131/2023-HORTSCI  

The aim of this study was to determine the effects of elevated CO₂ (eCO2) on the quality and cadmium (Cd) accumulation of vegetables grown in soil with a background Cd level or in Cd-contaminated soil. We used four types of vegetable: pak choi (Brassica rapa L.), water spinach (Ipomoea aquatica Forssk.), cherry radish (Raphanus raphanistrum subsp. sativus (L.) Domin) and pepper (Capsicum annuum L.). Cd stress significantly reduced vegetable vitamin C and reducing sugar content; however, under eCO2, vitamin C and reducing sugar content levels were significantly higher than they were under...

Apples and pears are the main temperate fruit tree species, and metabolic disorders may occur during their development and post-harvest storage periods, leading to physiological diseases. In this study, we detected the phenylalanine ammonia-lyase (PAL) enzyme and related metabolites involved in phenylpropanoid metabolism in the pulp of pear with hard-end or cork spot and in the pulp of apple with bitter pit. These three physiological disorders differed in phenylpropanoid metabolism and had similar PAL activity, but their polyphenol, flavonoid, and lignin contents changes were completely. For fruits with the three types of physiological metabolic disorders,...

Yttrium nitrate improves the longevity of campanula cut flowers through strengthening the enzymatic antioxidant system and maintaining water balanceOriginal Paper

Hort. Sci. (Prague), 2024, 51(4):286-296 | DOI: 10.17221/171/2023-HORTSCI  

We explored the role of yttrium nitrate (Y(NO3)3) in extending the longevity of campanula cut flowers. The results showed that Y(NO3)3 significantly enhanced the enzymatic antioxidant system, including the superoxide dismutase, peroxidase, ascorbate peroxidase, dehydroascorbate reductase, monodehydroascorbate reductase, glutathione reductase, glutathione peroxidase, and glutathione S-transferase. In this way, Y(NO3)3 increased the DPPH scavenging activity and decreased the malondialdehyde content and electrolyte leakage, which implied that Y(NO3)3 strengthened the antioxidant capacity. Meanwhile, Y(NO3)3 significantly improved the production of the...

Anatolian sage (Salvia fruticosa Mill.) is widely used in many food, cosmetics, and pharmaceutical sectors. This study aimed to determine the differences in essential oil components and seasonal changes in the components of six clonally selected C-clones and one natural population in a randomized block design with three replications. Samples were collected monthly from C-clones for two years, and essential oil rates were determined. Clonal heritability was between 0.00 and 0.78. When the best clone was selected from six clones, the genetic gain changed from 12.4 to 44.8 for the essential oil components. Assessment of all clones revealed that...

The physiological performance, growth and competitive ability of fruit trees are increasingly affected by the effects of global climate change, very different at a regional level, which mainly causes considerable changes in water availability. The purpose of this study was the evaluation of three sweet cherry cultivars from the Research Station for Fruit Growing (RSFG) Iași, Romania under the climatic conditions of 2022–2023 by performing physiological investigations into the water regime and the transpiration process through the stomatal conductance, the water content of the leaves as well as their dehydration rate after 24 hours. The obtained...

Hort. Sci. (Prague), 2024, 51(4):314-326 | DOI: 10.17221/25/2024-HORTSCI  

To investigate the regulation mechanism of exogenous plant growth regulators on the sugar accumulation of ‘Fengtang’ plum fruits, and to provide theoretical support for improving the sugar content of ‘Fengtang’ plum fruits. The expression of fruit sugar fractions and related genes was determined by spraying different concentrations of exogenous abscisic acid (ABA) and Gibberellic acid 3 (GA3) during the critical period of sugar accumulation in ‘Fengtang’ plum. The results showed that exogenous ABA treatment increased fruit soluble solids content, delayed the decline in fruit firmness, increased fruit sucrose and...

Hort. Sci. (Prague), 2024, 51(4):327-340 | DOI: 10.17221/69/2023-HORTSCI  

The aim of the study was to assess the impact of the use of biofertilizers on the degree of colonization of cucumber and tomato plant roots by arbuscular mycorrhizal fungi and the number of AMF spores in the rhizosphere soil. Two experiments were carried out in containers on cucumber and tomato plants under field conditions. The plants were fertilized with standard NPK fertilizer, mineral fertilizers: POLIFOSKA 6, Super FOS DAR 40 and urea in the full recommended dose and reduced by 40%, microbiologically enriched, and only with strains of beneficial microorganisms (Bacillus spp., Bacillus amyloliquefaciens, Paenibacillus Polymyxa, Aspergillus...

Iron chlorin is known to affect plant growth, but its potential applications in watermelon production have rarely been explored. To better understand its effects on the growth, photosynthesis, yield, and quality of watermelon in a greenhouse setting, a series of experiments were conducted using the variety ‘Sumeng 6’. At the flowering and early fruit expansion stages, the plants were sprayed with iron chlorin with mass concentrations of 0.001, 0.002, 0.004, and 0.008 μg/L (T1, T2, T3, and T4). Control plants were sprayed with water (CK). The growth index, root activity, photosynthetic pigment content, photosynthetic parameters, yield,...
