“…Arazá is native to the Amazonian region and exhibits severe fungus disease infection when growing in subtropical conditions (Donadio & Moro, 2004). This orchard has the optimum Amazonian tropical conditions required for arazá growth and ripening: annual average temperature of 25.1 C, average relative humidity of 85%, 3972 mm rainfall, and 1382 h per year of sunlight.…”

“…No Mato Grosso do Sul, o Cerrado abriga vários grupos de espécies, dentre as quais, representantes da família Myrtaceae que podem ser utilizados de forma ornamental ou na produção comercial na fruticultura regional, devido à qualidade dos frutos. O gênero Eugenia está entre os mais importantes dessa família, apresentando mais de 3.000 espécies, sendo que a maioria das nativas brasileiras possui frutos comestíveis (DONADIO; MORO, 2004;BARBEDO et al, 2005;VENDRAME;SILVA et al, 2005).…”

Objetivou-se com este trabalho avaliar a sensibilidade à dessecação e a longevidade durante o armazenamento de sementes de Eugenia pyriformis Cambess. (uvaia). Os frutos utilizados foram coletados em matrizes localizadas na cidade de Amambai-MS. Para o estudo da sensibilidade à dessecação, foi utilizado o protocolo baseado na redução do nível de hidratação das sementes a cada cinco pontos percentuais, obtendo-se sementes com teores de água de 45; 40; 30; 25; 20; 15; 10 e 5%. Para estudar a longevidade das sementes durante o armazenamento, foram testadas as condições de câmara fria e seca (16±1Cº/40% UR), geladeira (5±1Cº) e freezer (-18±1ºC) durante 30 dias, e as sementes que não foram submetidas ao armazenamento constituíram o tratamento-controle. A semeadura foi realizada entre areia a 20/30ºC com 10h de luz/14h de escuro em B.O.D. As sementes de uvaia são sensíveis à dessecação e não toleraram a secagem a 5% de teor de água. As sementes recém-beneficiadas apresentaram germinação de aproximadamente 77% e com a secagem até 5% houve a redução para 15% de germinação. A diminuição do teor de água provocou a redução da massa fresca, comprimento de raiz primária, hipocótilo e total de plântulas e tempo médio de germinação. As condições de armazenamento sob temperaturas baixas e a secagem reduziram a germinação das sementes, indicando assim o comportamento recalcitrante das sementes de uvaia.

The development of seedlings from fragments of monoembryonic seeds as an important survival strategy for Eugenia (Myrtaceae) tree species

The uncommon ability of monoembryonic seeds of Eugenia to develop seedlings after cutting or even after the removal of more than half of their storage tissue has recently been reported. Some Eugenia species are included among those at risk of disappearing, so the regeneration of plantlets from fragments of seeds could be an important mechanism both for the production of more than one normal seedling per seed and to understand the survival strategies of these species. Because the period in which this ability is present has not been studied, we analyzed the regenerative capacity of seeds of five Brazilian native species of Eugenia, considering two levels of maturity and three germination phases. Mature seeds have a greater potential to regenerate than immature ones; germinating seeds showed that the longer the root protrusion, the smaller the potential to regenerate new seedlings. However, our results clearly demonstrate that the ability to regenerate new roots or complete seedlings is present during a long period from the beginning of development until the late phases of germination. Cutting is potentially important to obtain plants on a larger scale. Because of intense predation of these seeds, this ability could be linked to an essential strategy for survival even after the removal of more than half of the storage tissues. As an alternative strategy to orthodox seeds, whose preservation is based on tolerance to desiccation, the recalcitrant seeds of Eugenia probably adopted the great reserve quantity and the regenerative capacity, allowing them to undergo successive germinations.
