Objective: The activities of alanine and aspartate aminotransferases, NADmalate dehydrogenase in the ontogenesis have been determined in leaves of durum wheat genotypes (Barakatli 95, Garagylchyg 2) with contrasting drought tolerance, cultivated under natural soil drought conditions. Methods/analysis: Enzymatic activities of aspartate and alanine transferases, NADmalate dehydrogenase were determined spectrophotometrically (Ultrospec 3300 pro, Amersham, USA). Measurements were taken at 340 nm for 1 min and the obtained results were expressed as µmol mg -1 *protein min -1 . The unequal variance two-tailed Student's t-test was applied for the analysis of the significance of differences between plants cultivated under irrigated and natural drought conditions. P≤ 0.05 was considered statistically significant. We used three samples for each treatment and performed the analysis twice. Findings : In flag leaves of the drought-tolerant Barakatli 95 genotype, the alanine aminotransferase activity increased ~2.7 and ~2.2 fold compared to the drought-sensitive Garagylchyg 2 genotype, under irrigated and natural drought conditions. According to the results, catabolism of amino acids is faster in the drought-sensitive Garagylchyg 2 genotype compared to the droughttolerant Barakatli 95 genotype under stress. Although the activity of all three enzymes studied varies in parallel in the ontogenesis of flag leaves, it is mostly dependent on leaf water content during the day. Novelty/improvement: The obtained data suggest that high enzyme activities in the Barakati 95 genotype play a role in achieving drought tolerance.

Rutin is a well hown flavonoid found in Artem'sia scoparia and some other plants. It exhibits multiple actions such as spasmolytic and inhibition of arachidonic acid metabolism. In this study we provide an evidence that ruth exhibits hepatoprotective activity in an animal model of hepatotoxicity.Wistar rats (200-250 g) were divided into 3 groups of 10 each.Group 1 served as control and received normal saline (10 mL/kg) and vehicle (1% rnethylcellulose; 13 mL/kg) orally. Group 2 was given 4doses of saline at 12 hrs interval and paracetamol was administered orally 1 hr post-uearment of the last dose. Group 3 was treated similar to that of group 2, except that rutin (20 mgKg) was administered instead of saline.In a parallel study on 3 similar groups, the treatment remained same except that paracetam01 was replaced by CCl, and vehicle was changed to olive oil (7.5 m L K g . Liver function was assessed after 24 hr of toxin administration by measuring serum aminotransferases (GOT and GPT).Acetaminophen (640 mglkg) produced liver damage as manifested by the rise in serum levels of GOT and GFT to 1013 f 268 and 686 f 219 lU/L (n=10) compared to respective control values of 118 f 6 and 39 f 07. Pretreatment of animals with rutin lowered (P

Lycopersicon esculentum Mill. — is one of the most important vegetables of Azerbaijan. Heterosis propagation is used to increase the yield and quality of Lycopersicon esculentum Mill., because traditional methods cannot be used to achieve this goal. Heterosis in tomato led to an increase in productivity by 20–50%. The paper presents a study to assess heterosis in tomato inbreeds for the development of hybrid varieties. Used hybrids obtained from combinations of Tom-1 × Masally. Commodity productivity of the plant differed from the maternal form, and the paternal productivity — 2 times from the paternal form. The hybrid forms of Tom-1 × Masally in terms of fruit mass and productivity had the effect of heterosis.
