The past year has seen the fruits of biotechnological manipulation of forest trees approach commercial application. Advances in somatic embryogenesis have brought mass clonal propagation of the top commercial trees closer to reality, and efficient gene transfer systems have been developed for a number of conifers and hardwoods. Radical alterations in the quantity and quality of lignin in wood h...

An efficient protocol for callus induction and somatic embryogenesis of Cyclamen premium Mill. Was developed. In this study we investigate difference between response of two explants type leaf and petiole and two medium salt concentrations MS and 1⁄2 MS on callus percentage and somatic embryo number. Media was non-significant on callus production but leaf explants was better than petiole and in...

Oil palm is one of the most economically valuable oil seed plants, but the expansion of plantations has been limited by availability of seedlings, as the conventional propagation is through seeds, which have low germination rates. One possible solution for the large-scale production is the use of somatic embryogenesis. The aim of this study was evaluate the effects auxins 2,4-D and picloram on ...

Three trials have been set up in Côte d’Ivoire to analyse the growth of six-year-old microcuttings produced from seedlings, 45-month-old somatic embryos of PB 260 and PR 107 and 31-month-old microcuttings of IRCA 18. The results show that Hevea in vitro plantlets produced by somatic embryogenesis or microcutting consistently grow as well as if not better than conventional budded plants. The dif...
