Several physical, chemical, and biological attributes of coffee seeds can be influenced by the drying and storage conditions. To propagate the recommended cultivars using seeds, it is often necessary to grow seedlings from genotypes of different maturation cycles, for which the mature seeds are only available in different moments throughout the year. This study aimed to test the germination of seeds of Coffea canephora Pierre ex A. Froehner from genotypes of early maturation, after being subjected to different periods of natural or artificial drying. For this end, two trials were developed, following split-plot (in time) scheme and completely randomized design, to study the moisture content of seed dried by two different drying process along 27 periods (between 0 and 320 hours), and the germinative potential, based on the germination speed index and proportion of germinated seeds after 30 days, of seeds dried by two drying process and 12 levels of seed moisture (between 50% and 8%). The results show that artificial drying at 35 ˚C removes seed moisture faster than the natural drying at 25 ˚C. Both drying methods can be used for decreasing seed moisture. However, the faster water loss negatively affects the germinative potential of seeds of genotypes of C. canephora of early maturation. The natural drying at 25 ˚C seems to have lesser impacts over the germination process, which may represent a good alternative if the seeds are stored at low levels of moisture.

Froehner a partir de genótipos de maturação precoce, após serem submetidas a diferentes períodos de secagem natural ou artificial. Para tanto, foram desenvolvidos dois ensaios, em esquema de parcelas subdivididas (no tempo) e delineamento inteiramente casualizado, para estudar o teor de umidade de sementes secas por dois diferentes processos de secagem ao longo de 27 períodos (entre 0 e 320 horas), e a germinação potencial, baseado no índice de velocidade de germinação e proporção de sementes germinadas após 30 dias, de sementes secas por dois processos de secagem e 12 níveis de umidade das sementes (entre 50% e 8%). Os resultados mostram que a secagem artificial a 35˚C remove as sementes mais rapidamente do que a umidade de secagem natural a 25˚C. Ambos os métodos de secagem podem ser usados para diminuir a umidade das sementes. No entanto, a perda de água mais rápida afeta negativamente o potencial germinativo de sementes de genótipos de C. canephora de maturação precoce. A secagem natural a 25˚C parece ter menor impacto sobre o processo de germinação, o que pode representar uma boa alternativa se as sementes forem armazenadas em baixos níveis de umidade.

Due to the lack of information on the water demand of cocoa seedlings, empirical techniques have been used in the supply of water to the seedlings, potentializing losses in their growth and development. In this context, the present study aimed to determine the optimal irrigation depth for a good development of the genotype PS-1319 cocoa seedlings. The study took place at the Federal Institute of Espírito Santo-Campus Itapina, located in the Colatina, a city situated in the northwestern region of the state of Espírito Santo, Brazil, in an experimental greenhouse of the campus, between October 20 and December 15, 2017. The experiment was conducted in a completely randomized design (CRD) using 20 seedlings of the genotype PS-1319 cacao per treatment. The treatments consisted of daily applications of six irrigation depths, corresponding to 4, 6, 8, 10, 12 and 14 mm d-1, being evaluated their effects on the morphological parameters (leaf area; dry mass of the aerial part, dry mass of the root system and total dry mass; height of the aerial part and stem diameter) and the quality (Dickson quality index). The applied depths interfered, both in the development and the quality of the seedlings, with quadratic
adjustments for the leaf area, dry mass of the aerial part and total dry mass, diameter and for the Dickson quality index. The best responses to the studied parameters were provided by the 8.33 mm d-1 depth, which is recommended as an ideal for production of genotype PS-1319 cacao seedlings.
