1. Anatomical and histochemical studies of the somatic embryogenesis of Syagrus oleracea from immature inflorescences
Abstract Anatomical and histochemical studies were carried out during the somatic embryogenesis of Syagrus oleracea (Mart.) Becc. from immature inflorescences. Immature rachillas were inoculated on Murashige and Skoog medium with 4.52 μM 4-amino-3,5,6-trichloropicolinic acid (Picloram) and 2,4-diclorophenoxyacetic acid. Auxin concentrations were gradually r

3. HISTOLOGICAL ANALYSIS OF INDIRECT SOMATIC EMBRYOGENESIS INDUCED FROM ROOT EXPLATS OF OIL PALM (Elaeis guineensis Jacq)
RESUMO O dendezeiro é economicamente importante pela alta produção de óleo. A embriogênese somática indireta em dendezeiro demanda longo tempo de indução de calos e formação das plantas, sendo importante o estudo do potencial embriogênico dos calos e os mecanismos da embriogênese somática. O objetivo deste estudo foi verificar o efeito de difere

4. Influence of Silver Nitrate on Somatic Embryogenesis Induction in Arabica Coffee (Coffea arabica L.)
Abstract The influence of silver nitrate (AgNO3), benzyladenine (BAP), and indole-3-acetic acid (IAA) on low frequency somatic embryogenesis (LFSE) induction in Caturra and Catuaí arabica coffee was evaluated. For the Caturra cultivar, the production of somatic embryos was significantly increased by adding AgNO3 to the semisolid culture medium. The highest

5. Somatic embryogenesis in the commercial papaya hybrid UENF/Caliman 01 relying on plantlet production from sexed adult hermaphrodite donor plants
Abstract: Somatic embryogenesis from explants from hermaphrodite papaya mother plants is an alternative for the production of true-to-type plants without the need for sexing. This study aimed to analyze hormonal and osmotic inducers in different somatic embryogenesis stages in the commercial hermaphrodite hybrid papaya UENF/Caliman 01. Leaf disks from in vit

6. Somatic embryos from Phalaenopsis classic Spotted Pink (Orchidaceae) protocorms
RESUMO: O presente estudo buscou induzir a formação de embriões somáticos em protocormos do híbrido Phalaenopsis Classic Spotted Pink em dois estádios de maturação fisiológica aos 80 e 120 dias após a inoculação das sementes (DAIS). Os protocormos foram inoculados em meio ½ MS suplementado com 0,1 mg L-1 de ANA e 3 mg L-1 de TDZ. Aos 15 dias de

7. Morpho and Cytological Differentiation of Calli of Eucalyptus grandis x Eucalyptus urophylla During Somatic Embryogenesis
ABSTRACT The aim of this study was to induce and analyze embryogenic calli from two types of explants (leaves and meristems) of the hybrid Eucalyptus grandis x Eucalyptus urophylla. Leaves and meristems of plants kept in a nursery were disinfected and inoculated in Petri dishes containing MS culture medium supplemented with different concentrations of the gr

8. The effects of an osmoregulator, carbohydrates and polyol on maturation and germination of ‘Golden THB’ papaya somatic embryos
Abstract This study evaluated the effect of osmoregulators and carbohydrates on the maturation and germination of somatic embryos of papaya ‘Golden THB’. Cotyledon explants from papaya seedlings germinated in vitro on basal MS medium were cultured on somatic embryogenesis induction medium (IM) containing MS salts, myo-inositol, sucrose, agar and p-chloro

9. Somatic embryogenesis in Carica papaya as affected by auxins and explants, and morphoanatomical-related aspects
ABSTRACT The aim of this study was to evaluate somatic embryogenesis in juvenile explants of the THB papaya cultivar. Apical shoots and cotyledonary leaves were inoculated in an induction medium composed of different concentrations of 2,4-D (6, 9, 12, 15 and 18 µM) or 4-CPA (19, 22, 25, 28 and 31 µM). The embryogenic calluses were transferred to a maturati

10. Efficient In Vitro Somatic Embryogenesis and Plant Regeneration from Mature and Immature Embryos of Wheat ( Triticum aestivum L.)
ABSTRACT An efficient regeneration system is a pre-requisite for the application of genetic transformation and functional genomics study of important plants. In this study, the effect of different factors (plant growth regulators, casein hydrolysate, aspartic acid and ascorbic acid) on in vitro embryogenesis and regeneration of Arta, Bahar and Zagros cultiva

11. Large-scale, high-efficiency production of coffee somatic embryos
Abstract The study aims to compare the efficiency of previously used liquid media for coffee, evaluating NAA concentrations in liquid medium and proline in semi-solid medium in the regeneration of somatic embryos and asses concentrations of BA and IAA in the maturation of embryos in temporary immersion bioreactors. For the regeneration of globular embryos fr

12. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w
