Abstract

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.

  • Micropropagation has expanded to include various crops, fruit plants, vegetables, trees, medicinal and aromatic plants, and is now a multibillion-dollar industry worldwide.

    “Micropropagation, initially applied to ornamental plants [5], has expanded to include various crops, fruit plants, vegetables, trees, and medicinal and aromatic plants, and is now a multibillion-dollar industry worldwide [6].”

    From Somaclonal Variation and Clonal Fidelity in Commercial Micropropagation: Challenges and Perspectives (2025) · cites this paper as [5]

    The paper discusses micropropagation across diverse plants, including fruit crops, trees, and medicinal plants (References; Section 4.4), and describes its commercial use (General Discussion). It does not give a worldwide market value or say the industry is worth multiple billions of dollars. The separate claim about its initial use in ornamentals is attached to [5], not this source. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
