In vitro regeneration ability of four varieties potato (Solanum tuberosum) was evaluated for plantlet production applying hormonal concentrations and combinations. Shoot root characteristics were observed at 15 days after inoculation sprout explants. There significant variation found among the treatments in studied traits. The genotype Chollisha exhibited superior performance genotypes. Out tea...
An efficient in vitro protocol has been established for somatic embryogenesis and plantlet conversion of Korean wild ginseng (Panax ginseng Meyer). Wild-type and mutant adventitious roots derived from the ginseng produced calluses on Murashige and Skoog (MS) medium supplemented with 0.5 mg/L 2,4-dichlorophenoxyacetic acid and 0.3 mg/L kinetin; 53.3% of the explants formed callus. Embryogenic ca...
The biological effects of heavy-ion beam irradiation on cultured tissues of cyclamen were investigated by establishing an irradiation-mediated mutation breeding protocol for producing a new variety of cyclamen. Initially, a callus, a somatic embryo, and a plantlet were irradiated with C ion beam at doses of 10, 20, 40, 60, and 80 Gy. Distinct mutants were not obtained in plants regenerated from...
Berberis tinctoria Lesch. Is an endemic plant to high hills of Nilgiris having lot of medicinal properties. For its better conservation through mass multiplication, attempts have been made to standardize tissue culture technology. The results of the study exhibited that the basal medium containing BAP and NAA each at 0.5 mg/1 was found to be the optimum for callus formation. Shoot proliferation...
In present experiment callus induction and plantlet regeneration of four sesame varieties (Oltan, Yekta, Varamin and Single Branch Naz) have been considered in different environments with different hormone combinations. In order to evaluate callus induction, after surface sterilization of seeds, diploid embryos were isolated and cultured on related media enriched with 1.5, 2, 2.5 and 3 mg l-1 2...
The magnetic field (MF) is considered as a biophysical treatment to change the growth and development parameters. Current research was carried out to evaluate the effect of different intensities of MF (0, 45, 60, 70 and 75 mT) on seed germination and some morphologic and physiologic parameters of Rudbeckia hirta L. in dry and humid conditions for 30 min. Results showed that the MF trea...
This experiment aims was to study the effect of concentration aloe vera juice and get which shows better growth number leaves roots on Dendrobium orchid plantlet in Hybrid-vitro results. carried out at Tissue Culture Laboratory, Faculty Agriculture, Winaya Mukti University, began May August 2019. The experimental design used a Completely Randomized Design with 5 treatments replications namely: ...
In this study, physiological and morphological responses of five almond cultivars to drought stress were investigated under in vitro conditions. Plantlets from five commercial almond cultivars (Supernova’, ‘Tuono’, ‘Sahand’, ‘Ferragnes ’ and ‘Shahroud 21’] were established in MS medium containing 0.5 mg per liter BAP and then subcultured in MS proliferation medium containing 1 mg per liter BAP...
