salicylic acid play an important role in plants physiological processes. in this research the effect of salicylic acid on induction of somatic embryogenesis and plant pigments synthesis in the phloem and petiole explants of carrot in the b5 medium was investigated. we added treatments with 0, 0.5, 1.5, 2 and 3 mm to culture medium by experimental base on the randomized design to investigate the...

Somatic embryogenesis is the process by which somatic cells are induced into an embryogenic state, followed by differentiation into embryos. Somatic embryogenesis, in addition to being a method of propagation, can serve as an experimental tool for research into plant embryo development. This is a review of the current literature on in vitro plant somatic embryogenesis and the molecular advances...

abstract in this research, the effects of ba with different concentrations (0, 0.5, 1, 1.5, 2, 2.5 and 3 mg/l) in combination with iba (0, 0.01 and 0.1 mg/l) on bud growth and shoot proliferation and tdz with different concentrations (0, 1, 2, 3 and 4 mg/l) in combination with 0 and 0.5 mg/l iba on somatic embryogenesis from different parts of immature cotyledons (proximal, median and distal) w...

frequency of somaclonal variation in embryogenic calli and plants of olea europaea l cv.kroneiki derived from somatic embryogenesis were examined by randomly amplified polymorphic dna (rapd) analysis. radicle and cotyledon (proximal part) of mature zygotic embryo were cultured in omc medium supplemented with iba (5 mgl-1) and 2-ip (0.5 mgl-1). somatic embryogenesis was induced in calli of radic...

Somatic embryogenesis is affected by several factors. In this research project, we studied the effect of explant size, wounding and desiccation treatments on somatic embryogenesis and their conversion into plantlet among three genotypes of soybean. The explants were sampled from immature embryos of soybean in three different sizes (3, 5 & 7 mm) with wounding treatment on half of each, and then ...

Many of the regulatory processes occurring during plant embryogenesis are still unknown. Relatively few cells are involved, and they are embedded within maternal tissues, making this developmental phase difficult to study. Somatic embryogenesis is a more accessible system, and many important regulatory genes appear to function similar to zygotic development, making somatic embryogenesis a valua...

this study was carried out to investigate the morphological and anatomical aspects of somatic embryogenesis in date palm. lateral bud and shoot tip explants excised from young offshoots were cultured on ms medium with 2,4-d. somatic embryogenesis was in-duced by transferring the calli produced on the same medium without hormones. micro-tome sectioning of paraffin-embedded specimens was carried ...

abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...
