Germination of Syzygium malaccense and Syzygium jambos seeds under different thermal conditions and seedling morphology Rev. Bras. Frutic.
Nacata,Guilherme; Andrade,Renata Aparecida de.
Abstract The objective of this research was to analyze the influence of temperature on seed germination and seedling morphology for the S. malaccense and . S. jambosFor germination, 250 seeds of each species, of ripe fruits, were used, which were washed in running water, dried in room condition for 24 hours and disinfected. The seeds were placed in plastic boxes with medium texture vermiculite substrate and submitted to different temperatures: 20, 25, 30, 35ºC and 20-30°C in BOD`S, in a completely randomized design. The variables analyzed were: daily germination percentage, polyembryony and GSI. For morphological characterization, 30 seeds of both each species, submitted to a temperature of 30oC and samples were collected at intervals representative of...

Maturation stages of fruit development and physiological seed quality in Physalis peruviana Rev. Ciênc. Agron.
Sbrussi,Cesar Augustu Gasparetto; Zucareli,Claudemir; Prando,André Mateus; Silva,Bruna Vicentin de Almeida Barbosa da.
In fleshy fruits such as the Physalis, in which the seeds are the main form of propagation, there is disagreement about the appropriate physiological stage for harvesting in order to obtain high-quality seeds. The objective of this study was to determine the stage of maturation of Physalis peruviana, using the colouration of the fruit and calyx, and relative to the physical aspect of the fruit and the physiological aspect of the seeds. The following five stages of maturation were studied: green calyx and fruit (A); green calyx and yellow fruit (B); yellowish-green calyx and yellow fruit (C); straw-coloured calyx and yellow fruit (D); straw-brown calyx and intensely yellow fruit (E). Physical evaluations were determined using the diameter, length and...
