Abstract

Licuri ( Syagrus coronata (Mart.) Becc.) is an ornamental palm tree native of Brazil with great economic potential, because it provides raw material for manufacturing a wide range of products. The objective of this study was to assess the morphology of the fruits, diaspores, seeds, seedlings, and saplings of Syagrus coronata . The study was performed at the Laboratory of Seed Analysis (LSA) of the Federal Rural University of Pernambuco/Academic Unit of Garanhuns-PE, by using licuri fruits collected from the rural area of Caetes-PE. It was evaluated fruit morphology, diaspores, seeds, seedlings and saplings. Germination, in the form of cotyledon petiole emergence, began 15 days after sowing, is hypogeal, cryptocotylar, and remote tubular. It is slow and uneven, extending up to 60 days after the first eophyll appears. The saplings have alternate, pinnate, glabrous, entire leaves with parallel venation and sheath invagination. The primary roots persistent, the secondary roots arise from the stem root node in the primary root, and lateral roots only fasciculate was evidenced when the change was 300 days, and must remain in the nursery for at least 360 days after germination before taking it to the field, due to the slow development of this species.

Highlights

Palm trees belong to the Arecaceae (Palmae) family and consist of about 2,600 species in more than 240 genera

The fruit of Syagrus coronata (Mart.) Becc is a fleshy drupe whose color varies from light to dark green when immature and yellow or orange when ripe

Summary

Introduction

Palm trees belong to the Arecaceae (Palmae) family and consist of about 2,600 species in more than 240 genera. Brazil has the third most palm species diversity worldwide, with about 387 species and 37 genera of native palm trees, which have several uses (COSTA; MARCHI, 2008). They are widely exploited by local native communities living in the areas with the vegetative and reproductive parts are used, which demonstrates the nutritional, economic, and ecological importance of these species, in addition to their social value to different communities (OLIVEIRA et al, 2010). The nuts are used in the manufacture of coconut sweets, granola, and animal feed, while the endocarps are used to make high quality charcoal; these uses of have lowered the harvest of other endangered Brazilian tree species (CARVALHO et al, 2006; LORENZI et al, 2006)
