The drought tolerance of canola cultivars viz., Shirale, Oscar, Con-II, Rainbow and 19H was investigated after exposure to drought stress at various growth stages in a pot experiment. Water stress was imposed at flowering and pod filling growth stages. Data of various physiological (leaf chlorophyll a & b, proline and protein contents) and agronomic attributes (number of pods/plant, seeds/pods,...
Plants can perceive environmental changes and respond to external stressors. Here, we show that OsNAC2, a member of the NAC transcription factor family, was strongly induced by ABA and osmotic stressors such as drought and high salt. With reduced yields under drought conditions at the flowering stage, OsNAC2 overexpression lines had lower resistance to high salt and drought conditions. RNAi pla...
ABSTRACT This study was conducted with the objective of evaluating quantum yield, photosynthetic pigments and biomass accumulation mini watermelon cv. Sugar Baby, under strategies irrigation saline water potassium fertilization. The experiment in a randomized block design, 8 × 3 factorial scheme, three replicates, corresponding to eight applied at different phenological stages crop (control - l...
This study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. Different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. Genotypes were sown under normal irrigation and moisture stress conditions. In stres...
In order to study the effects of bio fertilizers application on quantitative and qualitative yield, proline content and activity of some antioxidant enzymes in sunflower (Helianthus annus L. var. Urofelor) in different irrigation withholding levels, a factorial experiment was conducted based on randomized complete block design with three replications in research farm of faculty of Agricultur...
Many plant species are induced to flower by stress. Stress-induced flowering has been studied mostly in the short-day plant pharbitis (also called Japanese morning glory; Ipomoea nil, formerly Pharbitis nil). In this article, physiological characteristics, the regulation by salicylic acid (SA) and the expression of flowering-related genes in stress-induced flowering in pharbitis are reviewed. P...
The research on reducing the water consumption in conventional cropping system is one of the important strategies to improve the water use efficiency in agriculture. In order to investigate the effect of time of potassium application under different irrigation regimes on millet grain yield and protein percent, a field experiment was carried out in Agricultural Research Center of Yasuj, Iran, in...
BACKGROUND: Humic acid is a natural polymeric composition which is produced as a result of decaying organic matters in soil, peat and lignin to increase crop product. OBJECTIVES: Assessment the effect of different irrigation regime and humic acid on red bean production and correlation coefficient between measured traits. METHODS: Cu...
Background and objectives: Ducrosia anethifolia is one species which belongs to Apiaceae family that is used to improve the odor of foods and drinks. It is used also to treat catarrh, headache and backache in folk medicine. The herb is also reported to relax the mind and body and induce a peaceful sleep. The growing stage has an important role in quantity and quality o...
Rosemary (Rosmarinus officinalis L.) is an important medicinal plant that contained a wide range of secondary metabolites such as rosmarinic acid. In this study, essential oil content and composition and rosmarinc acid were determined at three phenological stages (before flowering, full flowering and fruit set stages). Hydro distillation method was used for essential oil extraction and GC and ...
