Increasing quality and vase life of cut flowers play vital role in flower production industry. . Lisianthus (Eustoma grandiflora cv. Echo) has short vase life and it has been revealed that ethylene directly affect the initiation and process of senescence of petals. In this study, the effects of Silver and silicon nanoparticles with four concentrations of 0, 10, 20 and 40 mg L-1 with 4% sucrose...

Oregano and thyme essential oils are used for therapeutic, aromatic and gastronomic purposes due to their richness in active substances, like carvacrol; however, the effects of the latter on the central nervous system have been poorly investigated. The aim of our study was to define the effects of carvacrol on brain neurochemistry and behavioural outcome in rats. Biogenic amine content in the p...

using haploid technique in breeding of sugar beet as an allogamous plant will facilitate breeding efforts. in this method,a pure line with a desirable genotype can be achieved by unfertilized ovule culture. therefore ovule culture was done from populations with numbers: 27621, 27624, 27626 and 27629. young flowering stems were collected and ovules were isolated from the flower buds after steril...

embryogenic calli production in vitis is mainly possible by use of such regenerative tissues as anther and ovary. because of long periods of time required for obtaining such tissues, use of such vegetative organs as leaf explant would be a promising alternative. towards this end, leaf explants were taken from two varieties of ‘flame seedless’ and ‘red sultanina’ to be raised in. ms medium, cons...

The aim of this investigation was to assess the effect of different antioxidants on the motility andmembrane integrity of the ram semen during storage at 5ºC for 0, 12, 24, 48 and 72 hrs after collection anddilution. A total of 57 ejaculates from 12 Bakhtiary rams was collected by artificial vagina and were extended1 : 3 with egg yolk-citrate buffer, which was containing one of the following an...

background and aims: the antioxidant and anti-inflammatory effects of carvacrol were reported. the aim of the current study was an investigation the relaxant effects of carvacrol on acetylcholine-induced contraction in isolated rat's ileum. materials and methods: in this study, the tissues separated from ileum were fixed on the organ bath containing tyrode's solution. the amplitude of...

In rats, the pharmacological (interoceptive) effects of 0.4 mg/kg nicotine can serve as a conditional stimulus in a Pavlovian conditioning task. Nicotine administration is paired with intermittent access to a liquid sucrose unconditional stimulus; sucrose is withheld on saline sessions. An increase in sucrose receptacle entries (goal tracking) on nicotine sessions indicates conditioning. Rats w...

PURPOSE The aim of this study was to evaluate the effects of pomegranate (PMG) extract and carvacrol (CARV) on methotrexate (MTX)-induced oxidative stress and bone marrow toxicity. METHODS Wistar albino rats (32 rats) were divided into four groups (n=8): Group 1 was control; Group 2 was given a single intraperitoneal injection of methotrexate (20 mg/kg); Group 3 was treated with carvacrol (73...

This study was designed to determine whether N-acetylcysteine (NAC, C(5)H(9)-NO(3)S), a compound from Allium species may be used as a complementary therapeutic agent, to inhibit high-sucrose induced-obesity and its effects on glucose tolerance, in vivo low-density lipoprotein (LDL)-oxidation and serum oxidative stress in rats. Initially, 24 male Wistar rats were divided into two groups: control...

Plant regeneration and somatic embryogenesis through interspecific hybridization among different Carica species were studied for the development of a papaya ringspot virus-resistant variety. The maximum fruit sets were recorded from the cross of the native variety C. papaya cv. Shahi with the wild species C. cauliflora. The highest hybrid embryos were recorded at 90 days after pollination and t...
