ABSTRACT
 
Phytohormones are widely used in Solanum tuberosum plants to accelerate the in vitro multiplication process. The main objective of this research was to evaluate the effect of different concentrations of phytohormones: auxins (IAA, IBA, NAA), cytokinins (6-BAP, TDZ, Zeatin), and gibberellins (GA3) on the morphological characteristics of Solanum tuberosum L. var. Cecilia. In vitro established plants were used, and the in vitro multiplication was performed using nodal segments cultured in MS medium supplemented with 20 g.L⁻¹ sucrose, 7 g.L⁻¹ agar, and phytohormones. The plants were maintained under total fluorescent white light conditions. The number of nodes, number of leaves, plant height, and number of shoots were evaluated. At 21 days, the use of IBA (0.05 mg. L⁻¹ and 0.25 mg. L⁻¹) increased the number of nodes and the number of leaves. Meanwhile, Zeatin concentrations of 0.05 mg. L⁻¹ and 0.1 mg. L⁻¹ increased the number of leaves, plant height, and number of shoots. Additionally, the concentration of 0.15 mg. L⁻¹ increased the plant height compared to GA3, and the concentration of 0.15 mg. L⁻¹ increased the number of nodes in S. tuberosum var. Cecilia plants. Based on the results of this study, it was concluded that IBA, Zeatin, and GA3 promoted the in vitro multiplication of S. tuberosum var. Cecilia plants.

INTRODUCTION
 
Solanum tuberosum L., commonly known as potato and belonging to the Solanaceae family1, stands out as the world's fourth most important food crop due to its high productivity and nutritional value for human consumption2. In 2017, global production reached 388 million tons cultivated over 19.5 million hectares3.
 
The primary global challenge in potato cultivation lies in reducing yield losses caused by the degeneration of planting material associated with various diseases 4. The most economically significant losses are caused by late blight (caused by Phytophthora infestans de Bary)5-7. This disease can devastate crops within two weeks under high humidity conditions 8. Moreover, it can survive even in adverse conditions and quickly spread through soil, water, rain, and wind9. Similarly, viruses pose a significant threat to potato crops worldwide. Viral infections are concerning not only due to the noticeable decline in production but also because the disease often lacks visible symptoms10.
 
The known susceptibility of this crop to disease, primarily viral infections, implies a scarcity of high-quality seed, significantly restricting potato production in several countries12,13. Acquiring certified seed can be difficult for farmers due to its high cost or limited availability14. However, enhancing seed quality through healthy and virus-free potato plantlets and microtubers15 is crucial. This improvement can lead to a yield increase of 15% to 20%16.
 
Micropropagation technology represents an alternative to conventional propagation and has proven to be effective in systematically eliminating viral infection19, ensuring the acquisition of high-quality and disease-free planting material20-22. This technology offers a solution to the challenge mentioned above in potato production23. It is based on cultivating plant cells, tissues, organs, seeds, protoplasts, or embryos in a sterile environment within a nutrient medium24,25. Factors such as temperature, photoperiod, humidity, light, and medium components must be meticulously controlled to provide an optimal growth environment26,27.
 
The culture medium is one of the most critical aspects that directly influences the success of the micropropagation technique28,29. The addition of plant hormones in appropriate quantities is crucial for regulating plant growth and development30-32. Among the growth hormones, cytokinins and auxins are commonly employed33,34. Among cytokinins, 6-benzylaminopurine (6-BAP) and kinetin (KIN) stand out for their ability to stimulate cell division and shoot development. On the other hand, key auxins include 1-naphthaleneacetic acid (NAA), indole-3-butyric acid (IBA), and indole-3-acetic acid (IAA), which play a crucial role in the overall development of plants35,36.
 
Although phytohormones significantly regulate the growth and development of in vitro-cultured plant tissues37, their effects can vary considerably depending on factors such as plant species, genotype, and culture conditions. This variability can pose challenges in successfully reproducing plants through micropropagation 38,39. Another critical aspect is the loss of tissue regeneration capacity over time. Moreover, excessive or inappropriate use of phytohormones can lead to undesired effects, including shoot deformations, hyperhydration (excessive tissue moisture)41-44, necrosis, or explant oxidation45.
 
Based on the issues mentioned earlier, the present study aimed to evaluate the effect of different concentrations of phytohormones, including auxins (IAA, IBA, NAA), cytokinins (6-BAP, TDZ, Zeatin), and gibberellins (GA3), on the number of nodes, number of leaves, number of shoots, and plant height of Solanum tuberosum L. var. Cecilia.
 
 
 
 
MATERIAL AND METHODS
 
The experiment was conducted at the Plant Biotechnology Laboratory of the Faculty of Agricultural Sciences at the Technical University of Ambato, located in the Cevallos canton, Tungurahua province, from April to September 2022.

Evaluations
 
The plant length (cm), number of leaves, number of nodes, and number of shoots per plant were determined at 21 days for each experiment.

 
Experimental design and statistic analysis
   
A completely randomized design was employed for each experiment. A control group (without phytohormone application) was included for each type of phytohormone. The data obtained for the variables, including the number of leaves, number of nodes, and number of shoots per plant, were recorded using SPSS version 26.0. Normal distribution was assessed using the Kolmogorov-Smirnov test, and homogeneity of variance was examined using Levene's test. For variables that did not meet these requirements, the Kruskal-Wallis test was used, followed by the Mann-Whitney U test. The significance level was set at 95%.

DISCUSSION
 
Influencia de concentraciones de auxinas (ANA, AIB, AIA) sobre la multiplicación in vitro de plantas de papa var. Cecilia.
 
Auxins are plant hormones primarily known for their role in plant root development 46. In the in vitro cultivation of S. tuberosum, adding auxins to the culture medium can enhance the formation of roots in the explants. The concentration and type of auxin used can influence the degree of stimulation of root formation 47. For instance, naphthaleneacetic acid (NAA) is a commonly used auxin in plant micropropagation and has been shown to induce root formation in various plant species 48, including potatoes.
 
Auxins can regulate cellular growth by influencing gene expression in cell division and elongation 49. It has been demonstrated that they can activate the expression of genes responsible for synthesizing structural cellular proteins and enzymes involved in cellular expansion and growth 50. This regulation directly impacts the proper development of tissues during in vitro multiplication 51.
 
In addition to these direct effects, auxins can interact with other phytohormones, such as cytokinins and gibberellins, to coordinate tissue growth and in vitro culture development 52. The relationship between different phytohormones and their balance in the culture medium are critical aspects to consider in optimizing the in vitro multiplication process of S. tuberosum 53.
 
The concentrations of naphthaleneacetic acid (NAA) and indole-3-acetic acid (IAA) used in the study may have been insufficient or excessive to promote an increase in the number of leaves, nodes, shoots, and plant height 54,55. If the concentrations were not within the optimal range, it is possible that no effect on in vitro multiplication was observed 56,57. Research has determined that NAA did not influence in vitro multiplication of S. tuberosum when shoot height and multiplication rate were evaluated 58. Regarding the effect of indole-3-butyric acid (IBA), low concentrations positively impacted in vitro multiplication.
 
Influence of cytokinin concentrations (6-BAP, TDZ, Z) on the in vitro multiplication of Solanum tuberosum L. var. Cecilia plants.
 
Cytokinins are phytohormones that play a crucial role in plant growth and development 59, including in vitro multiplication of crops such as S. tuberosum. They are commonly used in plant micropropagation, where plant tissue is cultured under controlled conditions 60.
 
These phytohormones promote cell division and tissue expansion, significantly contributing to in vitro multiplication by enabling rapid cell proliferation 61. They can induce shoot formation and can develop into complete plants when properly cultivated 62. They are responsible for promoting meristem activity, which are regions of active plant growth, stimulating the production of new buds and shoots 63.
 
In addition to stimulating vegetative growth and development, cytokinins can delay cellular aging and promote longevity of plant cells 64, which is beneficial for maintaining the health and viability of in vitro cultured tissues over extended periods. Research indicates that supplementation of the medium with concentrations of 6-benzylaminopurine (6-BAP) ranging from 0.5 to 1 mg.L⁻¹ did not show an apparent effect on in vitro multiplication when evaluating the number of nodes and plant height in S. tuberosum group Phureja 65.
 
Some authors have noted that S. tuberosum cv. Almera and Diamante explants measuring 1 to 2 cm with 2 nodes, cultured in MS medium supplemented with TDZ and auxin concentrations showed positive effects by exhibiting more shoots per explant when using 3.0 mg.L⁻¹ of TDZ combined with 0.1 mg. L⁻¹ of NAA 67. However, in this study, high concentrations of Zeatin had no effect when used on the Cecilia variety. This could be attributed to the fact that each variety responds differently to a specific phytohormone.
 
Research conducted to evaluate the effect of Zeatin on the in vitro multiplication of S. tuberosum indicated that a medium supplemented with 0.1 mg.L⁻¹ of Zeatin + 0.5 mg.L⁻¹ of 2,3,5-triiodobenzoic acid (TIBA) promoted an increase in the number of shoots 68. Furthermore, they noted that higher concentrations inhibited shoot development. The obtained results are consistent with the findings reported by the authors.
 
Influence of gibberellin concentrations (GA3) on the in vitro multiplication of Solanum tuberosum L. var. Cecilia plants.
 
Gibberellic acid (GA3) can stimulate both cell elongation and division, resulting in increased growth of in vitro cultured plant tissues 69. It is a crucial factor in plant micropropagation, as greater cell growth leads to more shoots and, consequently, a higher multiplication rate 70. The use of GA3 in the micropropagation of S. tuberosum activates the expression of genes involved in the initiation and development of shoots, leading to increased shoot formation on in vitro multiplied plants 71.
 
GA3 can influence plant tissue morphogenesis, encompassing the formation of roots, stems, nodes, and leaves. This aspect is crucial for producing healthy seedlings that have a higher chance of surviving during acclimatization 72. Additionally, GA3 can affect various metabolic processes such as protein synthesis, photosynthesis, and nutrient uptake, directly contributing to a higher propagation rate under in vitro conditions by providing optimal conditions for the growth and development of plant cells 73.
 
Research conducted for the micropropagation of S. tuberosum using a liquid culture medium with different concentrations of phytohormones indicates that MS medium supplemented with 0.25 mg. L⁻¹ of GA3, 5 mg. L⁻¹ of pantothenic acid, 1 mg. L⁻¹ of thiamine and 20 g.L⁻¹ of sucrose, under constant agitation, yielded better results at in vitro multiplication stage 58. Similarly, some authors mentioned that a concentration of 0.1 mg. L⁻¹ of GA3 significantly increases plant height and the number of nodes and leaves. It was also observed that high concentrations of GA3 lead to a decrease in leaves number and number of nodes per explant 74. These findings are consistent with the results obtained in the present study.

CONCLUSIONS
 
The present study concluded that specific phytohormone treatments positively affected the in vitro multiplication of Solanum tuberosum L. var. Cecilia. The auxin IBA at concentrations of 0.05 mg.L⁻¹ and 0.25 mg.L⁻¹ increased the number of nodes and leaves. The cytokinin Zeatin at concentrations of 0.05 mg.L⁻¹ and 0.1 mg.L⁻¹ significantly improved leaf number, plant height, and shoot proliferation, while 0.15 mg.L⁻¹ Zeatin promoted increased plant height. The gibberellin GA3 at a concentration of 0.15 mg.L⁻¹ notably increased the number of nodes. These findings offer valuable insights for optimizing in vitro multiplication protocols for Solanum tuberosum L. var. Cecilia contributes to the efficient production of disease-free potato plantlets and promotes sustainable agricultural practices.
