Against the background of global climate change, drought stress has become one of the environmental limiting factors that can significantly influence the growth and development of crop plants. Drought stress conditions also cause changes in plant physiological and metabolic processes. The influence of soil drought on the mineral composition of the...
Article
Hyssopus officinalis L. is a promising essential oil plant of complex use containing various types of biologically active substances (BAS). The purpose of the research was twofold: study the features of accumulation of various types of BAS in H. officinalis plants grown in the foothill zone of the Crimea; assess the possibility to use them in perfu...
Article
The mineral composition of Allium cepa L. leaves was measured by using the scanning electron microscope of Japanese company JEOL, model JSM600LA with EDS system. 11collection samples of FRC “All-Russian Institute of Plants Genetic Resources named after N. I. Vavilov” and 4 samples of FSBSI “Research Institute of Agriculture of the Crimea” were stud...
Conference Paper
We developed an optimized method for the production of flavored oils for salad dressing containing 4-5 times more aromatic substances compared to original mustard oil and having an optimal fatty acid composition. An application 2019135136/10(069439) for the invention “Method for producing flavored vegetable oils for salad dressing” was submitted to...
Conference Paper
Based on the conducted research, a method with an internal standard for the quantitative determination of the content of individual phenolic compounds – carvacrol and thymol in essential oils of Thymus vulgaris L., Monarda fistulosa L., Origanum vulgare L., Satureja hortensis L., Satureja montana L. was developed. The internal standard – oxygen-con...

The scheme of induced chemical mutagenesis of treatment of Allium sativum L. air bulbs of winter garlic bred by FSBSI “Research Institute of Agriculture of Crimea”, grown in a breeding nursery, has been developed. Two chemical mutagens of the first group, capable of transferring alkyd compounds to other plant cells were used in the study. Different...

Thirteen collection samples of Allium cepa L. of different ecology-geographical origin grown in the Crimea conditions are given. Morphometric characteristics of the bulbs - the form index, the diameter, the height, the weight, the thickness and the quantity of rich skins are analyzed. The greatest output of standart production (90 - 95.6%) was obse...

... Other shallot cultivars need different treatments to initiate flowering (Marlin et al., 2018). These treatments include the addition of GA3, vernalization, and exposure to long photoperiods (Sopha et al., 2014;Pramukyana and Den-Respatijarti, 2018;Nemtinov et al., 2021). Differences in flowering abilities and times complicate crossing genotypes with each other and introgressing new traits through TSS production in breeding programs. ...
... Molecular indicators of water stress speeded accumulation of active forms of oxygen that leads to the development of oxidative stress, the change of chlorophyll structure, decrease in photosynthetic pigments and metabolites, and the plant cells damage (Hernandez et al., 2001;Munne-Bosch et al., 2013;Getko et al., 2019). Mineral elements are not only structural components, but also play an important role in the enzyme activity, osmotic pressure control for cell turgor and growth, and acid-base and water-salt metabolism (White and Brown, 2010;Nemtinov et al., 2020). Increased stability to drought stress mostly depends on the plant's mineral accumulation (Waraich et al., 2011;Khan et al., 2012). ...
