42 ARTIGO 2 Growth rings in lianas of Leguminosae family from Atlantic forest in Rio de Janeiro, Brazil Arno F. N. Brandes 1* and Cláudia F. Barros 1 1) Escola Nacional de Botânica Tropical, Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, Rua Pacheco Leão 915, Jardim Botânico, CEP 22460-030, Rio de Janeiro, Brazil. Short running title: Growth rings in lianas Artigo submetido ao “Botanical Journal of Linnean Society”
43 ABSTRACT The anatomical features of growth rings of 8 lianas from Leguminosae family, occurring in mountainous relief within Atlantic forest of the Rio de Janeiro State, south-eastern of Brazil, were studied. Four species showed distinct growth rings. The others presented cambial variants and growth rings of sporadic occurrence. The cambial variants observed were stem with xylem furrowed and lobed stem. Semi-ring-porous, marginal parenchyma, fibrous zone and radially flattened latewood cells were the main features that mark the growth rings. The species with cambial variants have some boundaries made by pith flecks and traumatic canals. Piptadenia adiantoides, Piptadenia micracantha, Senegalia tenuifolia and Dalbergia frutescens show well-distinct growth rings in macroscopy and microscopy, that suggests the utilization in futures growth rings researches. ADDITIONAL KEYWORDS: cambial variants – Mimosoideae – Papilionoideae – secondary xylem – tropical region – wood anatomy.
