An experiment was conducted to study the different biochemical constituents imparting resistance and susceptibility rust of sorghum disease caused by Puccinia purpurea Cooke. For this, five resistant (R) susceptible (S) genotypes were inoculated at 30 days after sowing (DAS) studied both inoculation (DAI). Reduction in chlorophyll a, b, total chlorophyll, soluble protein, reducing sugar, non su...
Cadmium (Cd) is a heavy metal that causes oxidative stress in plants. In this study toxicity effect of Cd on Silybum marianum was investigated. Four treatments of CdCl2 (0, 300, 600, 400 and 900 μM) were evaluated in five replications using complete random design. Results of tolerance stress index severity of Cd stress on plants under various levels of treatments. Shoot dry weight, leaf area, c...
Strawberry (Fragaria × ananassa Dutch) is a widely grown fruit crop in the world due to its high aroma, taste, and nutritional value. In this study, the effect of foliar application of titanium dioxide nanoparticles on phytochemical modifications of strawberry cv. Sabrina under deficit fertigation conditions was investigated. The interaction effect of titanium dioxide nanoparticles (0, 6 and 12...
Given the increasing consumer demand for ready-to-eat products in recent years, the use of nano technology has been considered to improve the quality and increase the shelf life of fresh cuttings of fruit and vegetables. In this research, the effects of polypropylene contents of Nanoclay nanocomposites prepared by Bespar Aitec Company dishes, on quantitative and qualitative post-harvest indices...
abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...
Exposure to benzene has been monitored in petrol-pump workers and dry cleaners of Meerut City (India) by measuring phenol content of their urine samples. Average values for phenol in urine were higher in petrol-pump workers than dry cleaners. Alcoholic subjects excreted more phenol than smokers and non-vegetarians. It is concluded that alcohol can alter the susceptibility of man to benzene toxi...
A whole-cell recombinant bacterial sensor for the detection of phenolic compounds was constructed and used for the analysis of bioavailable phenols in natural samples. The sensor Pseudomonas fluorescens OS8(pDNdmpRlux) contains luxCDABE operon as a reporter under the control of phenol-inducible Po promoter from Pseudomonas sp. CF600. Expression of lux genes from the Po promoter, and thus the pr...
Jujube (Ziziphus jujuba Mill.) fruit is an important medicinal plant in Iran. The harvesting time is a crucial for jujube fruit quality. Several characteristics of jujube fruit when harvested at four development stages; white mature (light green), crisp mature (white-red), fully mature (red) and fully ripe (dehydrated brown) were evaluated. Fruit weight, diameter, volume, pulp to stone ratio, f...
This study was carried out to characterize some cherry cultivars (‘0900 Ziraat’, ‘Regina’, ‘Kordia’, ‘Sweetheart’, ‘Starks Gold’ and ‘Early Burlat’) in terms of phytochemical characteristics Eskisehir ecological conditions. As a result the research, vitamin C, total phenol, antioxidant activity, soluble solid content (SSC) pH were showed high variation among values determined range 2.53 (0900 Z...
