摘要

O reduzido conhecimento sobre aspectos básicos relacionados à autoecologia de espécies florestais nativas inviabiliza a elabora??o de estratégias para o manejo adequado de florestas, restaura??o e produ??o de mudas. Assim, o estudo teve como objetivo caracterizar a época de flora??o e frutifica??o, morfologia da flor, fruto, semente, plantula e muda de Holocalyx balansae Micheli (alecrim), além de analisar características físicas e fisiológicas de um lote de sementes. As observa??es fenológicas foram realizadas mensalmente. O lote de sementes foi formado a partir de seis indivíduos que apresentaram frutos maduros no mesmo período. A presen?a de flores ocorreu em dois períodos (fevereiro e junho a setembro), da mesma forma que os frutos maduros (novembro e de mar?o a abril). Observaram-se varia??es fenológicas, conforme o ano e entre árvores no mesmo período, sugerindo a marca??o de maior número de exemplares arbóreos marcados do que se deseja coletar. A germina??o é hipógea. O tamanho dos frutos e sementes foi variável, resultando em 793 sementes por quilograma, com 83% de germina??o, entretanto, sob condi??es ambientais, ao observar a emergência das plantulas, esse valor decresceu expressivamente (51%), devendo este ser um fator considerado no planejamento de produ??o de mudas.Palavras-chave: Papilionoideae; flora??o; frutifica??o; emergência; muda.?AbstractHolocalyx balansae: phenological and morphological aspects, and seed germination. The lack of knowledge about basic aspects related to autoecology of native forest species prevents the development of strategies for appropriate forest management, restoration and production of seedlings. This research aimed to characterize the time of flowering and fruitification, the morphology of flowers, fruits, seeds, seedling and changes of Holocalyx balansae Micheli (rosemary), and analyzing physical and physiological characteristics of a seed lot. We conducted monthly phenological observations. The seed lot had six individuals that exhibited ripe fruits in the same period. The presence of flowers occurred in two periods (February and June to September), just as the ripe fruit (November and March to April). We observed phenological changes during the year between trees in the same period, suggesting that it is necessary to mark a largest number of arboreal specimens than the ones you want to collect. Germination is hypogeal. The size of the fruits and seeds was variable, resulting in 793 seeds per kilogram, with 83% of germination, however, under environment conditions, observing seedling emergence, this value decreased significantly (51%), it should be a factor to be considered in seedling production planning.Keywords: Papilionoideae; flowering; fruiting; emergency; seedling.
