Nurseries producing apple and rose rootstock plants, apple orchards as well as rose production often experience replanting problems after several cultivations at the same site when a chemical soil disinfectant is not applied. The etiology of apple and rose replanting problems is most likely caused by soil-borne pathogen complex, defined as "replant disease (RD)". Symptoms typical of RD are redu...

OBJECTIVES Seed of Cucumis sativus Linn. is one of the herbal remedies has been traditionally used for diabetes mellitus treatment. We studied the effect of hydroalcoholic and buthanolic extract obtained from C. sativus seeds in a model of streptozotocin (STZ)-induced diabetic (type I) rats. MATERIALS AND METHODS Normal and diabetic male Wistar rats (STZ, 60 mg/kg, intraperitoneal) were treat...

Grass pea (Lathyrus sativus) is an ideal pulse crop for sustainable agriculture due to its superior agronomic traits such as deep penetrating root system, resistance many biotic and abiotic stresses rich protein content. Even with these traits, the considered orphan lower productivity presence of neurotoxin, b-N-ozalyl-L-adiamino-propanoic acid (ODAP). By following classical mutational breeding...

saffron or crocus sativus l. (c. sativus) has been widely used as a medicinal plant to promote human health, especially in asia. the main components of saffron are crocin, picrocrocin and safranal. the median lethal doses (ld50) of c. sativus are 200 mg/ml and 20.7 g/kg in vitro and in animal studies, respectively. saffron has been suggested to be effective in the treatment of a wide range of d...

BACKGROUND Crocus sativus L. (saffron), which belongs to the Iridaceae family, is widely cultivated in Iran. Cardiovascular effects of saffron has been established in some studies but the effects of chronic administration of saffron (C. sativus) stigma aqueous extract on blood pressure has not been investigated. OBJECTIVES In this study the effects of saffron (C. sativus) stigma aqueous extra...

Stigma of Crocus sativus L. (Iridaceae), commonly known as saffron, is the world’s most expensive spice and apart from its traditional value as food additive recent studies indicate its potential as antidepressant. Because saffron is expensive, using it daily to address depression may not be practical. Moreover, recent study indicated antidepressant effect of petal of Crocus sativus. As petal o...

1. Functional response models (e.g. Holling's disc equation) that do not take the spatial distributions of prey and predators into account are likely to produce biased estimates of predation rates. 2. To investigate the consequences of ignoring prey distribution and predator aggregation, a general analytical model of a predator population occupying a patchy environment with a single species of ...

In the present study, inhibitory effect of the methanol extract of Raphanus sativus root on lipid peroxidation has been carried out in normal rats. Graded doses of methanol extract of root of the plant (40, 80 and 120 mg kg(-1) body weight) were administered orally for 15 days to experimental treated rats. Distilled water was administered to experimental control rats. At the end of experiment, ...

Crocins are among the active components of the plant Crocus Sativus L. C. Sativus L. and its constituents were effective in different models of psychiatric disorders including anxiety and depression. Obsessive-compulsive disorder (OCD) is a common psychiatric disorder defined by the presence of obsessive thoughts and repetitive compulsive actions. The non selective serotonin (5-HT) receptor ago...

Micro RNAS (miRNAs) are a class of endogenous small non coding RNAs involved in the post-transcriptional regulation of gene expression. In plants, a great number of conserved and specific miRNAs, mainly arising from model species, have been identified to date. However less is known about the diversity of these regulatory RNAs in vegetal species with agricultural and/or horticultural importance....
