Exogenous Salicylic Acid

With the development of industry, synthetic drugs and their secondary metabolites bring some hidden dangers to environmental safety. As an excellent drug, salicylic acid is widely used in cardiovascular drugs, industrial dyes, skin care and acne products, etc. Therefore, it is possible to detect salicylic acid molecules, its derivatives or secondary metabolites in the natural environment. It should be noted that salicylic acid, as an endogenous signal molecule, can greatly affect plant growth. In this study, the common algal Spirogyra in fresh water was taken as the research object. The effects of exogenous salicylic acid on the growth of Spirogyra were analyzed through the changes of chlorophyll content and plant cross section during the growth of Spirogyra. It is found that the concentration of salicylic acid in the natural environment generally promotes the development of algae and improves their resistance to environmental stress. Therefore, as a possible correlation index of algal blooms, it deserves our attention.

Significant Difference

Salicylic acid (SA) is a common plant-produced signal molecule that is responsible for inducing tolerance to a number of biotic and abiotic stresses. An experiment was, therefore, conducted to test whether acetyl salicylic acid (ASA) application at various concentrations through seed immersion or foliar spray would protect muskmelon [Cucumis melo L. (Reticulatus Group)] seedlings subjected to chilling stress. Twenty-one-day-old plants pre-treated with ASA (0, 0.1, 0.25, 0.50 or 1.0 mM) were subjected to chilling stress for 72 h at 3 ± 0.5°C. ASA, applied either through seed immersion or foliar spray, was effective within the range of 0.1 to 1 mM in inducing tolerance to chilling stress in muskmelon seedlings; however, there was no significant difference between application methods. ASA significantly and curvilinearly affected all seedling growth and stress indicator variables tested except shoot dry weight. The best protection was obtained from seedlings pre-treated with 0.5 mM ASA. The highest ASA concentration used was slightly less effective in providing chilling stress protection. Even though both methods provided similar means of protection, due to its simplicity and practicality, immersion of muskmelon seeds prior to sowing in 0.5 mM ASA would be a more desirable method to induce tolerance to chilling stress. Key words: Cucumis melo, aspirin, chilling stress tolerance, gas exchange, electrolyte leakage

Ballast Water Management

Diagnostics in ballast water management is the main remedy to protect against the threat of spreading invasive species that can be carried in ships' ballast tanks. This phenomenon is getting better known and understood. New and more effective methods of preventing threats related to this are being developed. Procedures are created to ensure environmental safety in the face of ever-increasing transport by sea. The article characterizes both the background of the problem, basic diagnostic medics used in ballast water management, as well as procedures and basic techniques used to ensure the safety of the natural environment..

Currently, the concept of sustainable development of nature and society is gaining relevance, a key aspect of which is the development of the ecological network. In Ukraine, there is a regulatory framework for the formation of an ecological network of three levels - Pan-European, National and regional. One of the important problems is that in the developed schemes of regional eco-networks should be interconnected to the eco-networks of neighboring regions and countries. The main features of the ecological network of the Odesa region are due to its coastal position and location mainly in the Steppe, partly Forest-Steppe landscape zones. The region includes vast areas of coastal territories and coastal waters - coastal zones, which concentrate unique protected areas. Mandatory basis for the formation of ecological networks is land use. The proposed concept of geoplanning is based on planning developments of the main components of the territory: the natural environment; population; economic activity. The basic characteristics of the natural environment are the landscape map and physical and geographical zoning of the territory. Maps of resilience of the natural environment to man-caused load, natural and ecological potential of the territory, levels of ecological and economic balance have already been drawn up. This series of maps for the needs of planning the territory of Ukraine should be continued by project maps of national and regional ecological networks, as well as maps of ecological capacity of the territory for population settlement, various economic activities and the general level of economic development in general. For the needs of spatial planning it is necessary to emphasize the levels of anthropogenic and urban pressures on the natural environment in the settlement of the population. Allocation of water fund lands in kind and strict regulation of their use is the main prerequisite for the formation of ecological networks of Ukraine and its regions.
