The use of in vitro potato shoot cultures for protoplast isolation is desirable for consistent protoplast qualities. Ethylene build-up in the culture vessels causes problems for leaf growth (e.g. decreasing leaf surface, dry weight and chlorophyll) in shoot culture. Fifty to one hundred µM Silver thiosulfate (STS) produced a larger leaf area as a source of plant material for protoplast isolatio...

Background & Aim: Effects of ultra violet spectrum on plants due to their obligatory requirement for sunlight for survival are unavoidable. Direct effects of UV on plant growth and development are generally negative and usually they use many different defense mechanisms to acclimate and protect themselves. Material & Methods: The present research for the first time was conducted to investigate...

Lisianthus (Eustoma grandiflorum L.) is a very popular, ornamental plant. Due to low germination of its seeds, usual techniques for its propagation are not efficient. The present study was aimed to establish callus from explants of different plant parts of Eustoma grandiflorum L. Raf Shinners in B5, LS and MS media with modifications.  The results showed that among different plant parts, leaf e...

Background: Tooth avulsion is one of the most severe dental traumas which most often occur in children. When immediate replantation is not possible, storage in a proper media may lead to a prolonged survival rate. Aloe Vera is a cactus like plant with green, tapered leaves that are filled with a transparent viscous gel. This medicinal plant has significant anti-inflammatory, antioxidant, antiba...

Role of humic acids (HA) in plant tissue culture as plant growth regulators has been reviewed. Humic acid is a principal component of humic substances, which are the most important organic constituents of the soil (humus). Humus is defined as the organic matter in soil, a mixture of partially and totally humified substances. Leonardite is the best source for humic acid and it is extracted by us...

introduction: despite extensive studies about effects of crataegus monogyna on cardiovascular diseases yet, a few study has been undertaken antiarrhythmic property of this plant. aims of the present study were: 1) to determine the protective role of methanolic extract of c.monogyna on the rate-dependent model and the concealed conduction . 2) to explore the role of na+-k+ a tpase in the protect...

Micropropagation of Asclepias curassavica L. a medicinal plant valued for its medicinal properties has been carried out using two different plant culture media, Murashige and Skoog (MS) and L2. L2 medium proved to be superior to MS medium in terms of shoot multiplication and shoot length. Nodal explants showed enhanced organogenic response than shoot tip explants. Basal nodal explants produced ...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...
