Megjegyzések:The production of micropropagated plants in plant-tissue-culture laboratories and nurseries is the most important method for propagation of many economic plants. Micropropagation based on tissue-culture technology involves large-scale propagation, as it allows multiplication of a huge number of true-to-type propagules in a very short time and in a very limited space, as well as all year round, regardless of the climate. However, applying plant-tissue-culture techniques for the commercial propagation of plants may face a lot of obstacles or troubles that could result from technical, biological, physiological, and/or genetical reasons, or due to overproduction or the lack of facilities and professional technicians, as shown in the current study. Moreover, several disorders and abnormalities are discussed in the present review. This study aims to show the most serious problems and obstacles of plant micropropagation, and their solutions from both scientific and technical sides. This review, as a first report, includes different challenges in plant micropropagation (i.e., contamination, delay of subculture, burned plantlets, browning, in vitro rooting difficulty, somaclonal variations, hyperhydricity, shoot tip necrosis, albino plantlets, recalcitrance, shoot abnormalities, in vitro habituation) in one paper. Most of these problems are related to scientific and/or technical reasons, and they could be avoided by following the micropropagation protocol suitable for each plant species. The others are dominant in plant-tissue-culture laboratories, in which facilities are often incomplete, or due to poor infrastructure and scarce funds.

Cím:Quantifying Intergenerational Plasticity in Tomato: Temporal Divergence as a Cost-Effective Survival Strategy Against Drought Following Parental Ultrasound Priming / Dóra Farkas, Judit Dobránszki
Dátum:2026
ISSN:2311-7524
Megjegyzések:Understanding intra- and intergenerational adaptive strategies is essential for developing resilient crops. This study investigated these dynamics in Solanum lycopersicum L. cv. Micro- Tom by subjecting parental plants to ultrasound priming and drought stress, followed by drought treatment in the progeny. We introduced the Intergenerational Plasticity Ratio (IPR) as a framework to quantify how stress-response strategies shift across generations. Our results reveal a divergence in adaptation: while parental plants prioritize immediate survival through morphological reductions, the progeny exhibit refined phenological shifts as a cost-effective mechanism. The results suggest that ultrasound may serve as a priming stimulus, preparing internal signaling pathways for heightened stress readiness. These phenotypic shifts suggest that ultrasound-based priming could be explored as a potential non-chemical approach to influence crop resilience. This may allow plants to exhibit adaptive developmental timing in response to specific stressors; however, further research is needed to determine the scalability and stability of these effects across different environments.

Cím:Responses of Potato (Solanum tuberosum L.) Breeding Lines to Osmotic Stress Induced in In Vitro Shoot Culture / Hanász Alexandra, Dobránszki Judit, Mendler-Drienyovszki Nóra, Zsombik László, Magyar-Tábori Katalin
Dátum:2022
ISSN:2311-7524
Megjegyzések:In vitro experiments were conducted to study the responses of potato (Solanum tuberosum L.) genotypes to osmotic stress. In vitro shoot cultures of 27 breeding lines and their drought-tolerant parents (referent lines: C103 and C107) were tested under osmotic stress induced by addition of PEG 6000 (Mw = 6000; 5.0, 7.5, 10.0%, w/v), D-mannitol (0.1, 0.2, 0.3 M) and PEG 600 (Mw = 600; 2.5, 5.0, 7.5%, w/v) to the Murashige-Skoog medium. Stress index (SI) was calculated from shoot length (SL) and root length (RL), root numbers (RN) and the rate of surviving shoots (SR) (SISL;RL;RN;SR = Parameter(SL;RL;RN;SR) of treated shoots/Parameter(SL;RL;RN;SR) of control shoots x 100) to compare genotypes. In the average of each breeding line and concentration, the osmotic agents resulted in SI values of 40.1, 60.8, 82.6 and 76.0 for SISL, SIRL, SIRN and SISR, respectively. In general, all SI values of C103 and SIRL,RN of C107 were significantly higher than those of the breeding lines. Nine breeding lines were found to be promising based on their final ranking. According to the results, 7.5% and 10% PEG 6000 or 0.2 M and 0.3 M D-mannitol treatments proved to be suitable for the selection of osmotic stress-tolerant genotypes.

Cím:Ultrasound in plant life and its application perspectives in horticulture and agriculture / Anita Király, Dóra Farkas, Judit Dobránszki
Dátum:2025
ISSN:2311-7524
Megjegyzések:Acoustic vibrations may induce different changes in plants that perceive them, and plants themselves can also emit acoustic signals. The aim of this review was to cover the past ten years of plant acoustic research and its shortcomings, with a focus on the reflecting, sensing, and emission of ultrasound by plants. Ultrasonication may alter plant growth and development, and an increasing number of studies are being carried out to investigate its effects on both in vitro plant culture and greenhouse or field plant production, as well as on the biochemical and molecular functions of plants. In this paper, we summarized the progress in the use of ultrasound in horticulture and agriculture for enhancing plant growth and development, either in vitro or in vivo, improving yield and crop quality and increasing stress tolerance, as well as for special methodological applications, like sonication-assisted Agrobacterium-mediated transformation. Some research gaps, such as the lack of a precise mechanism for plant ultrasound emission, the possible participation of some reactive radicals in ultrasound signaling, the effect of ultrasound on the epigenome, the role of ultrasound in plant-to-plant communication, and whether there is a specific, sound perceiving organ, etc., were also presented. In addition, a predictive vision is described of how ultrasonication of plants and ultrasound detection emitted by plants can be used in the future to develop green and sustainable agricultural and horticultural technologies. Furthermore, based on our current knowledge, a proposal is presented to combine them with machine learning and artificial intelligence for developing novel production technologies.

Cím:In vitro micropropagation of Dianthus plumarius subsp. praecox, a wild carnation species, for ornamental horticultural and gene conservation purposes / Pál Szarvas, Dóra Farkas, Judit Csabai, Angéla Kolesnyk, Judit Dobránszki
Dátum:2025
ISSN:0304-4238
Megjegyzések:Carnation is important floral crop. The introduction of wild carnation species is carried out in parallel with research on existing species and varieties. Dianthus plumarius subsp. praecox is a wild species with an extremely high germplasm conservation importance. The most important step in the study of its cultivation is to propagate it in vitro under conditions of minimum impact on nature. Therefore, present work aimed to develop an in vitro micropropagation protocol for this species. Different types of cytokinins, such as 6-benzylaminopurine, 6-benzylaminopurine riboside, meta-topolin, N-(2-chloro-4-pyridyl)-N'-phenylurea, kinetin, N6-(2-isopentenyl) adenine, zeatin and adenine sulfate, was applied for the in vitro multiplication. Cytokinins were applied alone in a concentration of 4.5 ?M, or in the combination of 2.25 ?M BA and 2.25 ?M KIN. Their effect on the in vitro shoot multiplication and their after-effects on the in vitro rooting were tested. Based on the present detailed study, a micropropoagation protocol was developed, where high shoot multiplication rate (4.7 ? 0.4 shoot/explant with 25.1 ? 1.4-mm-long shoots) could be achieved using zeatin as cytokinin source in the shoot multiplication medium. For successful in vitro rooting 6-benzylaminopurine-containing medium was applied for 3 weeks after shoots multiplication phase on zeatin-containing medium, then shoots were conditioned for 2 weeks on plant growth regulator free medium directly before rooting. With this treatment hyperhydration of in vitro shoots could be decreased from 91 % to 12 % and high frequency (86.7 %) in vitro rooting was gained. Rooted in vitro shoots were successfully acclimatized in 71 %.
