The present studies report in vitro propagation of a rare and medicinally important orchid Vanda testacea through foliar explants. Explants were cultured on Mitra et al. (M) medium and its combinations with cytokinins (BAP, Kn 1 mgl each) and auxin (NAA 1 mgl) individually and in combination for initiation of regeneration response, proliferation of regenerants and subsequent development of plan...

The effects of salicylic acid (SA) and Putrescine (Put), on cut Narcissus was studied. SA (0, 100 and 200 mg l-1) and Put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 108 Narcissus cut flowers in horticulture laboratory of agriculture faculty of Islamic...

In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...

the present research was carried out to evaluate the response of seven selected persian leek accessions to in vitro gynogenesis. the experimental design was a factorial one based upon a completely randomized design of three culture media treatments b2d0 (2 mgl-1 ba), b2d2 (2 mgl-1 ba and 2 mgl-1 2, 4-d), and b2d4 (2 mgl-1 ba and 4 mgl-1 2, 4-d) along with seven persian leek accessions (gorgan, ...

Dog rose (Rosa canina L.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as Rosa hybrid and Rosa floribunda. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and d...

Lipid signals derived from lipolysis and membrane phospholipids play an important role in glucose-stimulated insulin secretion (GSIS), though the exact secondary signals remain unclear. Previous reports have documented a stimulatory role of exogenously added mono-acyl-glycerol (MAG) on insulin secretion from cultured β-cells and islets. In this report we have determined effects of increasing in...

The stabilization of swine wastewaters from swine confined housing by the combination of a upflow anaerobic sludge blanket (UASB) reactor and waste stabilization ponds is a viable alternative to minimize the environmental impact caused by inadequate disposal of swine wastewaters. In the present study, the polluting load of pre-decanted swine wastewater treated with a series of two 0.705 m(3) UA...

Aberrant glycosylation occurs in the majority of human cancers and changes in mucin-type O-glycosylation are key events that play a role in the induction of invasion and metastases. These changes generate novel cancer-specific glyco-antigens that can interact with cells of the immune system through carbohydrate binding lectins. Two glyco-epitopes that are found expressed by many carcinomas are ...
