| Popis: | Peach palm is a domesticated palm commercially important for the production of fruits and hearts of palm. Somatic embryogenesis, an effective technique for mass propagation, was successfully established for this species. Furthermore, a temporary immersion system improved plant regeneration. However, production can be further improved by understanding the peach palm’s growth dynamic and modifications of culture media. The aims of this study were to evaluate the growth of plantlets cultured in different culture media in a temporary immersion system and to correlate the results with nutrient uptake during the growth period. Somatic embryo-derived young plantlets approximately 1 cm in length were cultivated for 12 weeks in a twin flask system containing MS, Y3 or N6 salts, Morel and Wetmore vitamins and 3% sucrose, with a monthly medium refreshment. Growth was measured and mineral analysis of the plantlets was carried out after 12 weeks of culture. The Y3 and MS salts were the most appropriate for the plant growth. Number of roots was 52.52% higher and the root size was 40.42% between the N6 and MS medium and the root number in Y3 medium was 37.74% greater than in MS medium, which is important for post acclimatization survival. K and Na are important elements for peach palm. N is not required at such a high concentration as in Murashige and Skoog formulation. The Chu (N6) medium did not generate high quality plantlets, possibly due to the absence of some micronutrients, like Mo, Cu and Co. |
