A pot (0.5 dm3) experiment was carried out under greenhouseconditions using river sand as substrate irrigated with nutrient solution twice every day. Theexperiment that was a completely randomized design had six treatments and three replicates.The treatments consisted of nutrient solution free of K+ (control) or supplied with 2, 4, 6, 8 and12 mM of K+ as KCl salt. After germination and the period necessary for the plants to stabilizein conditions of the experiment they had been irrigated with K+- nutrient solution treatmentsduring 30 days. The experiment was harvested 80 days from transplanting. K+, Ca2+ and Mg2+contents in roots, stems and leaves were determined. Through the growth analysis the leafmass ratio, the efficiency of K+ translocation and use were calculated. The results haveshowed that Moringa oleifera was not responsive to the K+ external concentration above 2mM. The K+ accumulation in stems was higher than in roots and leaves. The treatments hadnot influenced on the translocation efficiency of K+ throughout the plants. Finally, the plantsshowed to be more efficient to use K+ under conditions of a lower concentration of this ion inthe nutrient solution. 2005 artículo científico 1519-5228 https://www.redalyc.org/articulo.oa?id=50050220 en http://www.redalyc.org/revista.oa?id=500 Revista de Biologia e Ciências da Terra application/pdf Universidade Estadual da Paraíba Revista de Biologia e Ciências da Terra (Brasil) Num.2 Vol.5 |
