Cabralea canjerana is a species that has ecological and economic importance for the Southern Brazil. This study aimed to characterize the biometry of fruits and seeds as well as the C. canjerana germinative process submitted to different substrates and temperatures. The biometric characteristics of fruits and seeds were analyzed with the aid of digital caliper. In the germination test, the substrates blotting paper, sand and vermiculite, and the temperatures of 20, 25 and 30 ºC were used. The germination percentage, mean germination rate (MGR), mean germination time (MGT), synchronization index (SI), fresh mass (FS) and dry mass (DM) of seedlings were assessed. The highest germination percentages occurred for vermiculite at three temperatures, blotting paper at 25 °C and sand at 20 and 30 °C. There was seedling formation in all treatments. The use of the sand substrate and the temperatures of 25 and 30 °C provided lower mean values of MGT and SI and higher mean values of MGR. The highest DM occurred with sand at the temperature of 20 ºC. The biometric characteristics of fruits and seeds varied. We recommend the use of vermiculite at temperatures of 20, 25 and 30 ºC, blotting paper at 25 °C and sand at 20 and 30 °C for germination tests.

Cabralea canjerana é uma espécie que possui importância ecológica e econômica para o Sul do Brasil. Este estudo objetivou caracterizar a biometria de frutos e sementes, assim como o processo germinativo de C. canjerana submetido a diferentes substratos e temperaturas. Analisaram-se as características biométricas de frutos e sementes com auxílio de paquímetro digital. No teste de germinação, foram utilizados os substratos papel mata-borrão, areia e vermiculita e as temperaturas de 20, 25 e 30 ºC, avaliando-se a porcentagem de germinação, velocidade média de germinação (VMG), tempo médio de germinação (TMG), índice de sincronização (I), massa fresca (MF) e massa seca (MS) de plântulas. As maiores porcentagens de germinação ocorreram com vermiculita nas três temperaturas, papel mata-borrão a 25 °C e areia a 20 e 30 °C. Houve formação de plântulas em todos os tratamentos. O uso do substrato areia e das temperaturas de 25 e 30 ºC proporcionou menores médias de TMG e I e maiores médias de VMG. A maior MS ocorreu utilizando-se areia sob temperatura de 20 ºC. Ocorreu variação das características biométricas de frutos e sementes. Recomenda-se a utilização de vermiculita nas temperaturas de 20, 25 e 30 ºC, papel mata-borrão a 25 °C e areia a 20 e 30 °C para testes de germinação.

Morphological integrations are unknown to forestry seeds. Understanding if seed measurements could predict its future seedlings features is a central question in seedling production. Hymenaea courbaril is an important species in this context and to the applied forestry.Thus, this study aimed to understand how some seedling features, could be related to the seed weight, and be affected by the population origin. The measurements consisted of seedling collar diameter, weight, protophilus area, central and lateral vein. Seed weight consistently varied between the populations in the study. Both populations had higher weight ranges than mentioned in the literature. There was no strong evidence that greater seed weight requires lesser time to germinate, conflicting with previous information. All the measurements presented enough shreds of evidence to be considered different when comparing the populations, except for the protophilus area and lateral vein length. All the studied measurements presented low correlation indexes to seed weight, except for seedling collar diameter, and seedling weight, which presented a moderate correlation. Protophilus elongation pattern was strongly associated with the leaf width when compared to midvein.
