periwinkle (vinca minor l.) is an evergreen perennial herbaceous plant that belongs to the family apocynaceae. the aerial part of this plant contains certain alkaloids such as vincamine, isovincamine and vincine. the most important of these is vincamine that re-duces blood pressure and promotes memory and the ability for mental concentration. mi-cropropagation could be a good alternative for th...

The frequency of shoot regeneration and multiplication of P. harmala was influenced by the type of explant and kind and concentration of hormones. Of the various seedling explants, cotyledonary node exhibited maximum shoot regeneration frequency from axillary region on MS medium supplemented with 5 microM BAP. Addition of 0.1 microM NAA enhanced the efficacy of BAP for multiple shoot regenerati...

An efficient and reproducible in vitro protocol for largescale multiplication of Liquorice (Glycyrrhiza glabra L.)has been described. Multiple shoots formation was significantly influenced by growth regulators, photoperiod,explant position, season of explant collection and culture passage. Nodal explants were collected atmonthly intervals to initiate in vitro cultures. The hig...

ABSTRACT Physalis ixocarpa Brot. ex Horm. is considered the most economically important species of genus. Tissue culture pointed out as a strategy for its propagation, but researches indicate that in vitro responses are genotype-dependent. This study aimed to evaluate morphogenesis P. green and purple varieties, view massive propagation species. The morphogenic capacity explants cotyledonary no...

orchids are one of the most popular plants in the world and among them phalaenopsis genus have the most sales in a global market. because of its hard propagation, micropropagation technique has been employed recently. in this study, we tried to find out useful protocol for commercial production through in vitro culture. at first, for seed capsules production, flowers were pollinated with hand i...

Soybean, a major legume crop, is the source of vegetable oil and protein. There is a need for transgenic approaches to breeding superior soybean varieties to meet future climate challenges. Efficient plant regeneration is a prerequisite for successful application of genetic transformation technology. Soybean cultivars are classified into different maturity groups based on photoperiod requiremen...

Cotyledonary node explants excised from 21 day old seedlings of T. arjuna produced multiple shoots when cultured on full strength MS or modified MS (1/2 strength major salts and Fe-EDTA) medium supplemented with different concentrations (0.1-1.0 mg/l) of BAP. Maximum 8.9 shoots/explant could be recorded after 30 days of inoculation on modified MS medium supplemented with BAP (0.5 mg/l). A proli...

Pieces of tissue were dissected from early chick and quail embryos (Stages XIII and XIV of Eyal-Giladi & Kochav, 1976; and stages 3-5 of Hamburger & Hamilton, 1951). These tissues were taken from three different regions of the early embryos, and from eight different regions of the older ones, and were derived mainly from the lower layer. Epiblast tissues were also used. The experiments were des...

A 28-year-old female presented with a palpable mass lesion on the superonasal aspect of her right globe and she had a progressive diplopia. She had a scleral encircling surgery with a Miragel explant (MIRA, Waltham, Mass, USA) for the tractional retinal detachment associated with pars planitis 9 years previously. On examination, she revealed restricted eye movements of her right eye. The magnet...
