Copyright: © 2026 by the authors. Open access under the Creative Commons Attribution (CC BY 4.0) licence.	Abstract: A single paragraph of 150–250 words. State (1) the aim and the question addressed, (2) the materials and methods, (3) the main results, and (4) the conclusion. The abstract must stand on its own: no citations, no undefined abbreviations, and no results that do not appear in the main text. An English abstract is required for every article; Russian and Uzbek abstracts are welcome and are printed as well. Key words: keyword 1; keyword 2; keyword 3; keyword 4; keyword 5 (five to eight keywords, specific to the article but common in the discipline, separated by semicolons) Leave the block on the left as it is — the editorial office fills it in during production. It is printed in the margin beside the abstract.

0. How to use this template

This template shows every section a manuscript may contain. Each section carries a short description of what belongs in it. Write over the sample text, keep the headings and keep the styles: the journal reads the title, authors, affiliations, abstract, keywords and reference list from them when it builds the formatted PDF.

Sections that do not apply to your work may be deleted, but keep the order of those you retain. When you have finished, delete this section 0 and renumber from 1.

Submit this file only. You do not need to produce a PDF: upload the .docx at https://pdca.uz and the journal typesets it, shows you the result, and creates the submission only after you confirm it.

1. Introduction

Place the study in a broad context and explain why it matters. Define the purpose of the work and its significance. Review the current state of the field, cite the key publications, and highlight controversial or diverging views where they exist. Keep the introduction comprehensible to botanists outside your particular speciality.

State the aim, question or hypothesis in the last paragraph. Cite references by number in square brackets in order of first appearance — [1], [2,3] or [4–6].

2. Materials and Methods

Describe the objects, the study area, the period and the methods in enough detail for the work to be repeated. Well-established methods may be summarised and cited; new methods must be described in full.

2.1. Study area

Give the geographical position, altitude range, climate and vegetation of the study area, and a map where it helps (Figure 1). State the coordinate system used.

2.2. Sampling and vouchers

State the sampling design, the number of plots or specimens, and the period of field work. Give herbarium acronyms for voucher specimens following Index Herbariorum, and the collector and collection number.

Give botanical names in full with the authority at first mention — for example, Tulipa greigii Regel — and set Latin names of taxa in italics. Follow the current International Code of Nomenclature. Use SI units throughout.

2.3. Data analysis

Name the software and version used, the statistical tests applied, and the significance level. Where large datasets are deposited in a public repository, give the accession numbers here.

Where generative artificial intelligence was used in preparing the manuscript — for generating text, data or graphics, or for study design or analysis — disclose it in this section. Use for language editing alone need not be declared.

3. Results

Give the results only, with references to the tables and figures; interpretation belongs in the Discussion. This section may be divided by subheadings.

3.1. Subsection

3.1.1. Subsubsection

Bulleted lists look like this:

• First bullet;

• Second bullet;

• Third bullet.

Numbered lists look like this:

1. First item;

2. Second item;

3. Third item.

The text continues here.

3.2. Figures and tables

Cite every figure and table in the text as Figure 1, Table 1, and place it near the point of first citation. Table captions go ABOVE the table; figure captions go BELOW the figure.

Table 1. This is a table. Tables must be real tables, not images, so that they can be re-typeset. Keep them within the column width where possible.

Variable	Group A	Group B
Parameter 1	0.00	0.00
Parameter 2	0.00	0.00
Parameter 3	0.00	0.00 1

1 Tables may have a footer.

The text continues here (Figure 1 and Table 2).

[ place the figure here ]	[ place the figure here ]
(a)	(b)

Figure 1. This is a figure. If a figure has several panels, label them (a), (b), … and describe each panel in the caption. Supply figures at 300 dpi or better; do not paste screenshots of charts. A figure that needs the full page width will be set across both columns automatically.

Table 2. A wider table. If a table does not fit in one column it will be set across both columns in the published article.

Taxon	Locality	Altitude, m	Vouchers
Taxon 1	locality	0000	TASH 00000
Taxon 2	locality	0000	TASH 00000

* Tables may have a footer.

3.3. Mathematical components

This is example 1 of an equation:

a = 1,	(1)

the text following an equation need not start a new paragraph. Punctuate equations as if they were part of the sentence. This is example 2:

S = 1 / (1 + exp(−Σ βi xi)),	(2)

where xi are the standardised predictors and βi the fitted coefficients. Refer to equations in the text as Equation (1).

4. Taxonomic treatment

This section is not mandatory. Include it when the article describes new taxa, new combinations, typifications or nomenclatural changes.

For each taxon give: the accepted name with authority, the place of publication, the type (holotype and isotypes, with herbarium acronyms), a full description, distribution, habitat, phenology, conservation status assessed against the IUCN criteria, and the specimens examined.

New taxa must cite a designated holotype and the herbarium where it is deposited. Nomenclatural novelties must be registered where the relevant code requires it.

5. Discussion

Interpret the results in the light of previous studies and of the working hypothesis. Discuss the findings in the broadest possible context, state the limitations of the study, and point out where further work is needed. Do not repeat the Results.

6. Conclusions

State the main conclusions and their implications. This section is optional if the Discussion already ends with them, and it must not repeat the abstract.

Back matter

Keep the statements below that apply to your article and delete the rest. They are printed after the conclusions and before the reference list.

Supplementary Materials: The following supporting information can be downloaded at: URL. Figure S1: title; Table S1: title.

Author Contributions: Describe the contribution of each author using the CRediT taxonomy — for example: “Conceptualisation, A.B. and C.D.; methodology, A.B.; formal analysis, E.F.; writing—original draft, A.B.; writing—review and editing, all authors. All authors have read and agreed to the published version of the manuscript.”

Funding: “This research received no external funding”, or “This research was funded by NAME OF FUNDER, grant number XXX.”

Institutional Review Board Statement: For studies involving humans or animals, give the approving body and the approval code, or state that ethical review was not required.

Data Availability Statement: State where the data supporting the reported results can be found, including repository names and accession numbers, or state that data sharing does not apply.

Acknowledgements: Acknowledge support that does not qualify for authorship — technical help, materials, access to collections, or administrative assistance.

Conflicts of Interest: “The authors declare no conflict of interest.” Declare any role of a funder in the design of the study, in the collection or interpretation of the data, or in the decision to publish.

The following abbreviations are used in this manuscript:

Appendix A

Appendix A.1

The appendix is optional. Use it for details and data that support the main text but would interrupt it — full specimen lists, extended tables, or supporting analyses. Every appendix must be cited in the main text.

Table A1. This is a table caption in the appendix. Figures and tables in appendices are numbered A1, A2, and so on.

Title 1	Title 2	Title 3
entry 1	data	data
entry 2	data	data

Appendix B

Further appendices follow the same pattern.
