| Authors: | E. Fernández Caldas, V. Garcia, A. Diaz |
| Abstract:
For the first time, a method of foliar analysis is proposed for Strelitzia, choosing as typical the youngest fully-developed leaf. The most frequent levels for the concentrations of N, P2O5, K, Ca, Mg, Fe and Mn in the leaves of well-developed plants have been determined. The different nutritional levels shown by plants in the open and by those in protected culture are noted. A description is given of the symptoms and nutrient disorders produced in the plant by iron chlorosis. | |
