Tomato samples were collected from the field of Absheron peninsula in Azerbaijan order to evaluate incidence main Tobamoviruses. According results serological and molecular tests, mosaic virus (ToMV), Tobacco (TMV), Pepper mild mottle (PMMoV) detected as single mixed infections (TMV + PMMoV; ToMV PMMoV) various tomato samples. It was found that Tobamovirus infection caused an increase content malondialdehyde, alterations activities peroxidase enzymes quantitative qualitative changes their...

The ascorbate-glutathione (AsA-GSH) cycle is a major pathway of H2O2 scavenging in plants. effect diurnal variations hydrogen peroxide (H2O2) content, the intensity lipid peroxidation (malondialdehyde, MDA), photosynthesis, antioxidants and antioxidative enzyme activities involved AsA-GSH metabolism has been studied comparatively leaves durum (Triticum Desf.) bread aestivum L.) wheat genotypes exposed to soil drought. Drought stress caused an increase content H2O2, MDA, alterations enzymes...

Land plants shorten their vegetation period during water deficiency.Under stress, wheat undergo several changes at the morphophysiological level.We tried to elucidate role of parameters and photosynthetic machinery in response drought followed by rewatering.Therefore, some traits two bread genotypes (drought-tolerant Gobustan, drought-sensitive Tale 38) were studied.The H2O2 content increased under both but recovered Gobustan genotype after rewatering.The isozymes peroxidase manifested...

Wheat is one of the most important crops to ensure food production globally. Understanding mechanism leaf senescence in wheat plays a crucial role improving its productivity and resilience under varying stress scenario. In this study, we investigated biochemical, functional, ultrastructural changes during genotypes with contrasting drought tolerance. For this, key parameters such as chlorophyll total protein content, membrane stability, malondialdehyde level, activity antioxidant enzymes...

Phytoplasmas are pathogens of important annual crops as well perennial cultures, causing different symptoms that ranges from yellowing to death infected plants.The aim the present work was analyze changes in activity metabolic and antioxidant enzymes, content total soluble sugars, tocopherols, phenolic compounds field-grown pepper plants (Capsicum annuum L.) under influence phytoplasma infection.The activities benzidine peroxidase (BPO) guaiacol (GPO) were observed increase leaves comparison...

Drought is one of the major factors limiting yield and quality crops in world. The activity antioxidative system to tolerate drought stress significant plants. In present study, activities isoform profiles catalase (CАТ), ascorbate peroxidase (APX), glutathione reductase (GR), superoxide dismutase (SOD) were analyzed four barley genotypes grown under soil water restriction. caused increase CАТ SOD all studied genotypes, while APX decreased. total GR increased substantially K 2778 St.Garabag...

A characteristic feature of C4 plants is the differentiation photosynthetic leaf tissues into two distinct cell types: mesophyll (M) and bundle sheath (BS) cells. We have investigated several biochemical parameters, including pigment composition, polypeptide patterns, fluorescence at 77K, activity photosystems ultrastructure chloroplasts maize (Zea mays L.) plants. It shown that BS ~2-fold higher chlorophyll a/b ratio than M chloroplasts, 6.15 3.12 respectively. The PSI apoprotein (68 kDa)...

Salinity is one of the most severe abiotic stresses for crop production. The present study was conducted to evaluate effect NaCl on growth and some biochemical parameters in chickpea (Cicer arietinum L.) seedlings. Chickpeas were grown hydroponically 14 days then treated with 0 mM 200 NaCl. Plants harvested experiment 7 after salt treatment. showed marked changes (fresh dry weight roots shoots) amount photosynthetic pigments. revealed that activity photosystems (PS I PS II) under stress...

The effect of elevated NaCl concentrations (0.5–4.0 M) on the proline content and activity free peroxidase in green alga Dunaliella salina have been investigated. It was revealed that tolerance to determined by functioning complex metabolic reactions including both necessary stress-induced accumulation high peroxidase. obtained data demonstrate testify a deep reorganization processes, occurring cells during adaptation salinity conditions.

Objective: Grapevine (Vitis vinifera L.) is one of the major crops widely cultivated for wine industry, as well production fresh and dried fruit in Azerbaijan. leafroll disease (GLD) affects vines throughout world considered most economically destructive among all virus virus-like diseases. Vineyard surveys were conducted to determine infection grapevine growing region Azerbaijan during 2019-2020. Methods/Statistical analysis: Forty-six samples collected from fields screened by rapid...

In the course of study, endemic plants flora Sumgayitchay River basin were studied. A total 265 species studied, which 215 are characteristic Caucasus and 50 naturally distributed in zone Azerbaijan. Endemic systematically analyzed for presence taxa. Of Caucasian species, 36 belong to family Asteraceae, 27 Fabaceae, 17 Brassicaceae, 16 Rosaceae, 14 Poaceae, Caryophyllaceae 10 Ranunculaceae. 266 higher listed Red Book Azerbaijan, 62 rare endangered common basin. Plants with a new habitat...
