The object of the study is ecologically significant flowering plants (rare, endangered, invasive and quarantine). The purpose of work is development of fundamental principles of molecular and cellular biotechnology, which focused on the epigenetic regulation of seed productivity of environmentally significant flower plants for conservation of natural and urbanized areas. Research methods field observations, laboratory studies, cytological methods and application of methods of mathematical analysis of the obtained data. To achieve this goal it was necessary to conduct a detailed study of the processes of epigenetic activation and inhibition of the reproductive systems of both flowering plants and invertebrates-until that pollinate these plants. For the first time for science it is shown that the implementation of short-term anesthesia in young females wild insect until carbon dioxide dramatically stimulated processes to iogenes (growth and development of ovaries and oocytes), which leads to faster development of the reproductive system with the ability to lay normal eggs, including in cases where the majority of individuals at birth have underdeveloped ovaries in norm perish, and not having to lay eggs. On a model object Megachile rotundata found that short-term anesthesia adults (10-20 minutes) significantly increases the fecundity of females, and, therefore, can be recommended for the development of technologies artificial increase in the number of insect pollinators. This method of increasing the reproductive capacity of insects-antill is a new direction in biotechnology and can be used not only to improve the efficiency of artificial breeding insects for pollination, but also to restore populations of rare and endangered insect species. Method of cultivation of pollen investigated in vitro germination of pollen of an invasive species Impatiens parviflora (which is very difficult to control in natural ecosystems) on different types of culture medium alone and in the presence of pollen of other plants. First established inhibition of germination of pollen grains Impatiens parviflora pollen of cultivated plants Rudbeckia hirta and Rubus serpens. At the same time revealed a stimulation of germination of pollen I. parviflora under the influence of pollen Lysimachia nummularia. Installed phenomena allow us to offer, on the one hand, a new method of reducing the number of specified invasive species that can be considered a new scientific direction in biological control of noxious plants. On the other hand, shows the new biotechnological potential direction of increasing the yield of entomophilous crops. Proposed quantitative indicator of the direction and strength of mutual influence of pollen of different species - the index of the PAS (a measure of antagonism-synergy).

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
