Two biochemical compounds of hydrogen peroxide and 24-epibrassinosteroid have significant biological effects on plant growth. In the present study, the effects of drought and its interaction with H2O2 and 24-epibrassinosteroid on the protein, sugars, essential oil percentage, photosynthetic pigments, phenols and flavonoids were investigated. For this purpose, a factorial experiment in a complet...

This study was conducted to assay the effects of methanol foliar application (0, 10, 20 and 30% v/v) and bed cover (control, white and black covers) on yield and some physiological traits of marigold as a factorial based on RCBD. The results revealed the significant interaction effects of bed cover and methanol foliar application on chlorophyll a content and plant height. The highest plant heig...

This work evaluated the effect of drought stress on seedling growth, protein, soluble sugars, and phenolic compounds of two cultivars of canola (RGS003 and Sarigol). Drought stress was induced with polyethylene glycol (PEG) at 0, 5, 10, and 15%. Drought stress increased root fresh weight in both cultivars and the effect of drought was more pronounced in RGS003. Shoot fresh weight reduced in Sar...

There are complex inter- and intra-relations between regressors (independent variables) andyield quantity (W) and quality (Q) in tobacco. For instance, nitrogen (N) increases W butdecreases Q; starch harms Q but soluble sugars promote it. The balance between (optimizationof) regressors is needed for simultaneous increase in W and Q components [higher potassium(K), medium nicotine and lower chlo...

in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...

Seasonal variations may influence the quality and quantity of biologically active ingredients in medicinal plants. Rosemary (Rosmarinus officinalis L.) a member of the Lamiaceae family, contains valuable antioxidant, anticancer and antibacterial substances, including Carnosic acid (CA). Here, the fluctuations of important active compounds present in rosemary leaf extracts collected in Golestan,...

investigation of physiological responses to water deficit in sesame (sesamum indicum l.) genotypes can help to identify effective mechanisms of plant resistance to stress. therefore, chlorophyll content, proline, soluble carbohydrates, net photosynthesis rate, stomatal conductance, maximum quantum efficiency (fv/fm), plant height and shoot dry weight in a complete block factorial pot experiment...
