Induction of somatic embryogenesis in absence of exogenous auxin can clarify some basic concepts of somatic embryogenesis.  Explants from leaf and petiole of Cucumber (Cucumis sativus) were used in this experiment for somatic embryogenesis using three different modified B5 basal media; boron and 2,4-D but no IAA as control (I), boron and IAA but no 2,4-D (II) and no boron, 2,4-D and IAA (III). ...

plant tissue culture is an alternative method of commercial propagation and is being used widely for the commercial propagation of a large number of plant species, including many medicinal plants. somatic embryogenesis is a process by which asexual or somatic cells are induced to form embryos in culture. somatic embryogenesis is a multi-step regeneration process starting with formation of pro-e...

Many factors may influence the efficiency of somatic embryogenesis. This capability may be differ with regard to media compositions, genotype, tissue, organ ontology and the stage of differentiation. The effects of five salicylic acid concentrations (0, 25, 50, 75 and 100 mM) on different stages of carrot somatic embryogenesis were studied using petiole and root secondary phloem explants as sta...

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 ...
