Ten grape rootstocks were subjected to moisture and salinity stress in two separate experiments. The influence of these stresses on gas exchange, water relation, and biochemical parameters was monitored at various stages of stress cycle. Both stresses indicated significant changes in the physiological and biochemical parameters studied. Some biochemical constituents increased by several folds in few rootstock cultivars which also recorded increased osmotic potential suggesting their role in osmotic adjustment. Some of the rootstock cultivars such as 110R, 1103P, 99R, Dogridge, and B2/56 recorded increased phenolic compounds under stressed conditions. The same rootstock also recorded increased water use efficiency. The increased accumulation of phenolic compounds in these cultivars may indicate the possible role of phenolic compounds as antioxidants for scavenging the reactive oxygen species generated during abiotic stresses thus maintaining normal physiological and biochemical process in leaves of resistant cultivars.

Induced Changes

The effects of subchronic exposure to copper (Cu) on lipid peroxidation, hemato-biochemical parameters, and the possible protective role of flavonoids Quercetin and (-)-Epicatechin were studied. Male Wistar albino rats were treated with Cu (560 mg/L, p.o. as CuCl2?2H2O for 5 weeks) and Quercetin and (-)-Epicatechin (40 mg/kg BW each, i.p., every third day during the last 3 weeks) alone or in combination. Cu increased the concentration of lipid peroxides, decreased the number of erythrocytes, hemoglobin and hematocrit values and increased the activities of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase. Coadministration of Quercetin and (-)-Epicatechin with Cu lowered the process of lipid peroxidation and restored examined hemato-biochemical parameters to control values. Our results indicate that Cu induced oxidative damage in erythrocytes, which led to anemia, while Quercetin and (-)-Epicatechin showed a protective effect on the hemato-biochemical processes in the blood of rats.

When the animals exposed to the high environmental temperature most of the physiological and biochemical parameters are disturbances. The heat-induced changes in each of thermoregulatory parameters as well as water, protein turnover or balances and hormonal levels may be used for evaluation the animal's adaptability to hot climate. Detection of such phenomena in the animals could be achieved by different indices. Most of indices which may be used for detecting the heat adaptability in animals are reviewed in this article paper.

Stem rot cause significant ecological and economic damage to forests. Affected stands are prone to windbreaks and windfalls. Value of wood and stability of stands are reduced. Despite intensive studies of resistance biochemical aspects to rotting diseases, role of phenolic compounds remains insufficiently clarified. The purpose of research was studying composition of phenolic compounds in birch leaves with a significant level of damage to the diameter of the trunk. Stem rot was determined by taking core from trunk. Biochemical composition of leaves determined by HPLC. There are 64 phenolic compounds was revealed. 24 factions identified, 45.83% of compounds in affected trees, content was increased. Flavonoids are prevail (63.64%). In 45.83% of compounds, content decreased. They had predominance of flavonoids (81.82%). All compounds possess antioxidant activity. They contain phenolglycosides, determining entomoresistance (arbutin, salicin, salidroside). The results showed that with significant infestation with rot, there is an increase in the content of phenolic compounds in the leaves, therefore, the biochemical processes of combating oxidative stress are activated. This is due to violation of physiological and biochemical processes in diseased trees.
