Biometria, armazenamento de sementes e emergência de plântulas de Talisia esculenta Radlk. (Sapindaceae)

Abstract: RESUMOEstudos de biometria de frutos e sementes são importantes para o entendimento da variabilidade existente nas espécies nativas. Apesar da importância ecológica e econômica de Talisia esculenta, não se conhecem as características biométricas dos frutos e não há informações sobre a emergência das plântulas. Objetivou-se caracterizar fisicamente frutos e sementes e estudar os efeitos do armazenamento sobre a emergência das plântulas. Analisou-se a biometria de 260 frutos e sementes. A emergência de plântulas… Show more

“…); consequently, this fact causes constant adjustments in the moisture content of the stored seeds (OAK; NAKAGAWA, 2012), determinant for the decay process, since the respiratory activity increases and hence the reservations consumption too (GUEDES et al, 2012). Gusmão (2008), storing T. esculenta seeds in laboratory natural environment (25 ± 2 °C and 68 ± 3% RH) for 0, 15, 30, and 60 days in Kraft paper bag, found reduction in seed water content from 40 to 24% at the 15 th day after storage, resulting in decrease of seedlings emergence from 88 to 16%. Results obtained in this study for T. esculenta were similar, so that at the 25 th storage day the seeds with 23% water content caused achieving only 12% of emerged seedlings.…”

“…Several authors verified the scarcity of biometric studies in native species, which could give support in programs for recovery of degraded area and genetic improvement due to the great variability in seed size, coloration of seed tegument and others [10]- [12]- [19]- [13]- [28]. Thus, the results of biometric studies of fruits and seeds represent important subsides to the establishment of techniques of eatable fruits [26].…”

“…Isso se dá em decorrência das Sapindaceae constituírem uma família cosmopolita que contém desde árvores e arbusto até lianas e ervas encontradas nos mais diferentes ecossistemas tropicais e subtropicais (SOMMER, 2009). Dentro das Sapindaceae é comum a presença de espécies que apresentem tanto cotilédones carnosos como T.esculenta (VIEIRA & GUSMÃO, 2008) e P.frutescens (PAOLI & BIANCONI, 2008), quanto cotilédones foliáceos como A.edulis (ABREU et al, 2005). Contudo, interessantemente, contrastando com o encontrado nesse estudo os cotilédones de K.paniculata descritos por MEYER (1976) são foliáceos.…”
