Acclimatation de vitroplants de bananier Musa sp. en culture hydroponique: impact de différentes concentrations en cuivre sur la croissance des vitroplants

Acclimatation of Banana's Vitroplants (Musa sp.) in Hydroponic Culture: Effects of Different Concentrations Copper on Growth of Vitroplants. Constraints due to copper and consequences of its accumulation in acclimatized banana in vitroplants have been studied in hydroponic culture. 0-100- 500-1000 ppm copper was added to the nutrient medium in hydroponic culture. At 1000 ppm, copper was accumulated in the roots but not in the aerial parts. Surprisingly, biomass of shoots and roots was augmented significantly at this concentration (with leaves as an exception). Plant height was reduced strongly even at 100 ppm CuSO4, although the copper content in shoots and leaves was very low.
