Summer fruit drop (June drop) is one of the main reasons for low yield in some citrus varieties in northern Iran. Recognition of physiological changes in fruit abscission zone (calyx) and application of suitable treatments would reduce or control abscission. Hence, the changes of auxin, cellulose, and polygalacturonase in calyx of Thomson navel fruitlets were measured and their relations with a...

The present study was carried out to evaluate the effects of thymol and carvacrol supplementation on performance, immune response, antioxidant enzyme activity and blood parameters of heat stressed broilers. Broilers were fed with commercial diet till 25 d of age, then they were allocated to a completely randomized design with a 3 × 2 factorial arrangement with 6 treatments including 3 levels of...

two factorial experiments were conducted to study the interactive effects of four levels of sucrose (0, 20, 40 and 60 g l-1), two levels of citric acid (0 and 160 mg l-1) and two levels of one of the following compounds (aluminum sulphate, 0 and 160 mg l-1 and silver nitrate, 0 and 120 g l-1) on vase life and quality attributes of lisianthus cut flowers ‘mariachi blue fonce.’ the experiments ca...

Objective: Paraquat (PQ) is a herbicide which induces oxidative stress and inflammation. Anti-inflammatory and anti-oxidant effects were shown for Zataria multiflora (Z. multiflora) and carvacrol previously. The effects of Z. multiflora hydroalcoholic extract and carvacrol on systemic inflammation and oxidative stressinduced by inhaled PQ were examine...

An important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. Ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. Nowadays, the use of compounds such as essential oils (EOs) and nanoparticles is applicable in microbiology studies. The main objective of this experiment was to study the s...

Tuberose (Polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. Thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. Tests were done to examine the effects on of nano-silver (NS) (0, 15, 30 and 45 mg L-1) and sucrose (0, 4 and...
