چکیده
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 differences were analysed according to mother plant juvenility; clonal characteristics and the stage of plant development at the time of planting. These first results are positive for in vitro plantlets, particularly since the analysis showed that before the true growth and production gain offered by this new planting material can be measured, it is essential to optimize the vigour of plants produced by in vitro culture, along with their growth in the nursery.

La cocoteraie mondiale couvre une superficie d’environ 11,5 millions d’hectares. Les petites plantations (< 3-4 ha) fournissent 96 % de la production mondiale de coprah. Sur ces petites exploitations, le cocotier est presque toujours associé à d’autres cultures. Les planteurs, soit en raison d’une vieille habitude culturale, soit sous l’effet d’une pression foncière grandissante, essaient de va...

The appearance of «dry» trees in rubber plantations and the development of Tapping Panel Dryness has been the subject of a considerable number of studies. The original causes of the disease have yet to be identified. Genetic factors at molecular level in the latex producing tissues determine susceptibility to tapping panel dryness. An experimental approach involves two-dimensional electrophores...
