Heavy metals are some of the most harmful chemicals in the environment today. Today, many scientists believe that the main factor that negatively affects the plant in saline conditions is the osmotic effect of salts. In conditions of soil salinity, the lack of plants causes dehydration of proteins, which negatively affects the physiological and biochemical processes of plants. Plants absorb heavy metals in different ways. It absorbs heavy metals from the soil through the roots and from the air through the stomata of the leaves, mainly through dust. The aim of the research is to study the influence of heavy metals on the physiological and biochemical processes of growth and development of maize varieties. The article presents the research results of the heavy metals influence on the elongation of seedlings and the synthesis of photosynthetic pigments during the germination of maize varieties. It is obvious that heavy metals affect the growth and plant development from the initial germination stage of corn kernels. The results of monitoring various effects of heavy metals on photosynthetic pigments are also presented. In addition, the length of the above- water and underground parts of the biomass, the ratio of dry weight to actual weight is the heavy metals effect on plants. For example, the leaves turned dark green, the stems twisted, did not fully open and turned pink. Under the influence of heavy metals, plant development, metabolism and photosynthesis are disrupted, as well as the normal course of respiration and photosynthesis. According to the results obtained, the impact of heavy metals on maize varieties significantly inhibits the accumulation and growth of biomass. In particular, the processes of plant root growth are suppressed. Differences in the tolerance of different varieties of heavy metals can be explained by their varietal characteristics and genetic basis. Currently, there is a theoretical and practical interest in the identification of ion-resistant forms of heavy metals, their ability to detect and reveal their nature, the development of ways to increase the impact and resistance of heavy metals on plants. Formulating the results of the study, it was found that different heavy metals concentrations (CuSO4 and CdSO4) negatively affect the growth of corn varieties. This can be seen from the tables below (tables 1, 2, 3, 4).

Studied the impact of prolonged watering of different amounts of citrate Ge, obtained by nanotechnology method, on the biochemical processes and antioxidant activity blood of male rats F2 1 and 2nd offspring in times of physiological and puberty. Established differently directed influence citrate Ge on the biochemical parameters bloods of animals of all ages – the increase of creatinine, phosphorus and triacylglycerol in male 4-month-old 1st offspring, while in animals 2 offspring grew albumin, calcium, phosphorus and triacylglycerols. Noted growth activity of antioxidant enzymes – catalase, SOD and GP animals 2-month-old 1st offspring, while the 4 months activity remained at the level of the control group, but males 2nd offspring grew – SOD and GP. For the watering 200 mkg Ge content hydroperoxides lipid and TBA products in the blood is reduced by 4 months of age the animals received both the first and second litters.

The leguminosae are second to cereal crops in agricultural importance based on area and total production, covering 14% of the cultivated land. Within the current and near future context, legume production is threatened by various abiotic stresses associated with climate change, which are expected to increase in number and severity during the following decades. Due to the important challenge to food security, it is important to understand how future legume crops can be bred to withstand adverse environmental conditions. The overall aim of this thesis is to gain further insights on the mechanisms involved in legume response to environmental conditions ([CO2], drought and temperature) through the integrated investigation of biomass, physiological and biochemical processes and the levels of metabolites and other compounds of the plants.

The Impact

High concentrations of ozone (O3) can have significant impacts on the health and productivity of agricultural and forest ecosystems, leading to significant economic losses. In order to estimate this impact under a wide range of environmental conditions, the mechanisms of O3 impacts on physiological and biochemical processes have been intensively investigated. This includes the impact on stomatal conductance, the formation of reactive oxygen species and their effects on enzymes and membranes, as well as several induced and constitutive defence responses. This review summarises these processes, discusses their importance for O3 damage scenarios and assesses to which degree this knowledge is currently used in ecosystem models which are applied for impact analyses. We found that even in highly sophisticated models, feedbacks affecting regulation, detoxification capacity and vulnerability are generally not considered. This implies that O3 inflicted alterations in carbon and water balances cannot be sufficiently well described to cover immediate plant responses under changing environmental conditions. Therefore, we suggest conceptual models that link the depicted feedbacks to available process-based descriptions of stomatal conductance, photosynthesis and isoprenoid formation, particularly the linkage to isoprenoid models opens up new options for describing biosphere-atmosphere interactions.

The Impact

In this work, we study an impulsive mathematical model proposed by Chavez et al. [1] to describe the dynamics of cancer growth and HIV infection, when chemotherapy and HIV treatment are combined. To better understand these complex biological phenomena, we study the stability of equilibrium points. To do this, we construct an appropriate Lyapunov function for the first equilibrium point while the indirect Lyapunov method is used for the second one. None of the equilibrium points obtained allow us to study the stability of the chemotherapeutic dynamics, we then propose a bifurcation of the model and make a study of the bifurcated system which contributes to a better understanding of the underlying biochemical processes which govern this highly active antiretroviral therapy. This shows that this mathematical model is sufficiently realistic to formulate the impact of this treatment.

Physiological And Biochemical

The ability of melatonin to regulate number of physiological and biochemical processes under different environmental stresses has been widely studied in plants. So, this investigation was done to study the protective roles of melatonin on Cicer arietinum L. grown under arsenic stress. Subjecting Cicer arietinum L. seeds to arsenic stress caused significant decreases in germination percentage, radicle growth, biomass accumulation, protein content and activities of antioxidant enzymes. On the other hand, melatonin treatment significantly increased growth parameters and protein quantity via improving antioxidant enzyme systems as compared with their corresponding untreated controls.
