in the present study, an efficient protocol has been developed for callus induction and production of ra in callus culture of satureja khuzistanica for the first time. in vitro callus induction was achieved from young shoot tip explants cultured on ms and b5 media supplemented with different concentrations of iba (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins bap and kin...

Plant cell signaling triggers the abscission of entire organs, such as fruit, leaves and flowers. Previously, we characterized an ADP-ribosylation factor GTPase-activating protein, NEVERSHED (NEV), that regulates membrane trafficking and is essential for floral organ shedding in Arabidopsis. Through a screen for mutations that restore organ separation in nev flowers, we have identified a leucin...

this study involves in vitro androgenesis of zea maysl. via anther culture. combination of two embryoinduction media (imss & ypm) in presence of different colchicine concentrations (0, 100, 200, 250, 300and 400 mg/l ) in the pretreatment medium (iml) andpretreatment duration (0, 3, 6 and 9 days) in twogenotypes (dh5×dh7 and eth-m82) were tested.after colchicine pretreatment, anthers were tr...

The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...

Studies of physiological diversity and its effect on the expression of traits in plants are used in breeding programs as a selective tool with the aim of selecting special attributes for creating a new product. In this study, the correlation coefficients among 17 horticultural traits of 34 genotypes from 11 different places of Semnan province were examined. A significant positive correlation wa...

there is some report about the hypoglycemic effect of juglans rejia l. leaf in alloxan induced diabetic rats and hypoglycemic effect of its fruit peel administered intra peritoneally. thirty male wistar rats divided into five groups, to evaluate the hypoglycemic and pancreas β-cells regenerative effects of oral methanolic extracts of leaf and fruit peel of walnut. rats were made diabetic by int...
