Two separate factorial experiments were conducted to study the effects of explant sources, plant growth regulators, sucrose concentrations, and light conditions on in vitro cormlet formation of freesia (Freesia ×hybrida Bailey 'Argenta'). Interestingly, it was observed that the pupae had lower contamination levels compared to mother corms. Using 40% sodium hypochlorite solution for 40 min, cont...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...

This study evaluated the anesthetic potential of thymol and carvacrol, and their influence on acetylcholinesterase (AChE) activity in the muscle and brain of silver catfish (Rhamdia quelen). The AChE activity of S-(+)-linalool was also evaluated. We subsequently assessed the effects of thymol and S-(+)-linalool on the GABAergic system. Fish were exposed to thymol and carvacrol (25, 50, 75, and ...

In this study, combined effect of two essential oils, Thymol and Carvacrol, with different concentrations in two methods on Gladiolous grandiflorous L. was investigated based on a completely randomized design with 3 replicates and four flower in each replicate. Sansusi variety applied that was red. In short term method, different concentrations of Thymol and Carvacrolin including 25+25, 50+50 a...

Studies show that Oryza sativa L. contains a structure named β-glucan with anti cancer properties. In the present study, a tissue culture for rice was carried out and β-glucan content was measured under various sugar and vitamin levels in basic MS medium. Seeds of Hashemi cultivar were cultured on MS medium. Two plant hormones, namely, 2,4-D (0, 1, 1.5, 2 and 3 mg/l) and kinetin (0,0.5, 1, and ...

this study was carried out to investigate the effect of differentpreservative solutions to improve the keeping quality of tuberose (polianthes tuberosa cv. single). these preservative solutions (treatments) were: t1= 2% sucrose + 200 mg/l agno3, t2= 2% sucrose + 200 mg/l agno3 + 25 mg/l citric acid, t3= 2% sucrose + 300 mg/l hqs, t4 = 2% sucrose + 300 mg/l hqs+ 25 mg/l citric acid, t5= 2% sucro...

in order to study the effects of silver thiosulfate (0.02, 0.05, 0.1 and 0.2 mm), humic acid (100, 500 and 1000 mg l-1), nano silver (5, 10, 25 mg l-1), salisilicacid (1, 2 and 4 mm) and sucrose (1%, 2.5% and 5%) on the vase life and some qualitative characteristics of cut narcissus var duch master floweres, two expriments were counducted in postharvest laboratory of mohaghegh ardabili universi...

Pollen viability and its germination capability for fruit set in are almond and peach essential. To optimize the pollen culture medium of almond and peach and selection of best medium, the present study was carried out with 48 different culture media containing different compositions including diverse levels of boric acid (0 and 100mg/1), calcium nitrate (0,150and300mg/l،), magnesium sulphate (...

necessary conditions for callus production from leaf and stem explants of norfolk island pine (araucaria excelsa l.) have been studied. ms and bm culture media containing 0.2, 0.5, 1, 2 and 5 mg/l naa, iba, 2,4-d and picloram supplemented with 30 g/l sucrose were used. callus was initiated in both culture media only in the presence of picloram and in the dark, but bm culture medium produced mor...
