| Resumo: |
The paper provides information about histochemical staining reactions in leaves and embryos of 'Coqueiro Anão' (Cocos nucifera). It was compared in vitro coconut and autotrophic palm leaves. Reactions for insoluble polysaccharides and acidic compounds, protein, extractable lipids, lignin and other classes of compounds were tested using histochemical tests. None sample gave positive reaction for lignin and phenolic compounds. All the samples gave positive reaction for protein, starch and insoluble polysaccharides while acidic compounds were positive only in in vitro leaves. Both in vitro and autotrophic leaves gave positive reaction for lipids showing presence of cuticle even in in vitro leaves. Only autotrophic palm leaves showed idioblasts containing calcium oxalate crystals.
