Germination of guatambu seeds subjected to two light regimes PFB - Pesquisa Florestal Brasileira
Guollo, Karina; Possenti, Jean Carlo; Felippi, Marciele.
Guatambu (Aspidosperma parvifolium A. DC.) is a species that faces extinction in different regions of Brazil. The aim of this study was to evaluate the influence of photoperiod on germination of guatambu seeds at 25°C. The statistical procedure used was factorial design with two factors. Factor A was seed lots (Mother tree A, B, and C) and factor B was photoperiod (dark and 12 h of photoperiod). Guatambu seeds are not affected by photoperiod condition during the germination process.

ELECTRICAL CONDUCTIVITY TEST APPLIED TO SEEDS OF FOREST SPECIES Sci. Agrar.Paran. / SAP
Guollo, Karina; Possenti, Jean Carlo; Del Quiqui, Erci Marcos; Felippi, Marciele; Debastiani, Aline Bernarda.
The evaluation of electrical conductivity is one of the fastest tests to evaluate quality and vigour of the seed, however, studies with forest species are scarce. Thus, the aim was to verify the possibility to evaluate the physiological quality of forest seed species by the individual and massal electrical conductivity test in different imbibition periods. The experimental material consisted of seeds of the Gallesia integrifolia, Handroanthus chrysotrichus, Lonchocarpus campestris and Pterogyne nitens. For the individual method, 80 repetitions of one seed were used, which were placed in individual containers containing 50 ml of distilled water. The following imbibition periods were evaluated: 2, 4, 6, 8, 24 and 48 hours. The tests were placed in a...
