two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...

Abstract The influence of TDZ on adventitious shoot regeneration from leaves the pear cultivars Conference and Abate Fétel, rootstock Farold ® 87 was investigated. Our main aim to set up efficient in vitro protocols for all these genotypes by using expanding elongated cultures as starting plant material. best results terms percentage were achieved half-strength Murashige Skoog basal medium supp...

three experiments were conducted in tissue culture and biotechnology laboratory of horticulture department of mohaghegh ardabili university in 2012. for the regeneration of plant from seed, different concentrations of naoh (5, 10, 15, 20 m) and various scarification methods with sandpaper (soft scarification, medium scarification and hard scarification) were used based on completely randomized ...

A comparative study on the effect of excess copper (Cu) supplied through leaves and root treatments in soybean plants is presented. Although Cu was accumulated in leaves upon both treatments, important differences were observed between Cu treatment of leaves and Cu supplementation in hydroponic medium. The application of 50 μM CuSO4 on leaves increased chlorophyll content, oxygen evolution acti...

Shoots of greenhouse-grown Algerian ivy (Hedera canariensis L.) were surface disinfected and explanted on modified Murashige and Skoog (MS) medium supplemented with BA (10 μM) and NAA (2.5 μM). One month later the shoots were transferred to MS proliferation medium supplemented with TDZ (0.1 or 0.5 μM) and NAA (40 μM). An average of three microshoots developed on each stem treated with TDZ. Prun...

The effect of various concentrations of thidiazuron (TDZ) with or without 2.7 μM of α-naphthalene acetic acid (NAA) on adventitious shoot formation of two Petunia hybrida cultivars was studied. Seeds from ‘Daddy Blue’ and ‘Dreams White’ cultivars were germinated in vitro. Expanded leaves from both seedlings and regenerated shoots were taken as explants. Explants were placed on MS media supplied...

Plants react differently to various media concentration and constituents. Growth of Senna alata (linn) inoculated on woody plant media (WPM) and Murashige & Skoog (MS) supplemented with growth regulators were investigated. Mature seeds were collected from the medicinal garden of National Centre for Genetic Resources and Biotechnology (NACGRAB), Ibadan; latitude 70221N; longitude 30 551E. Seeds ...

recently, tan spot disease of wheat caused by pyrenophora tritici-repentis(died.) drechsler has become very important disease in northern parts of iran and causes severe yield loss. although the anamorph of the fungus has been reported previously on infected leaves from mazandaran province (forotan et al., 1995), but there is no report on mass production of conidia in laboratory and the teleomo...
