LA CULTURE DE LA STRELITZIA REGINAE AUX ILES CANARIES ET L’APPLICATION DE L’ANALYSE FOLIAIRE

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.
