Seeds of native forest species for food and seedling production have a growing demand that impacts the need for studies involving seed storage in order to maintain good levels of germination quality. Thus, scientific analyzes that explore the physiological potential of the seeds of these species are necessary, especially for the pink pepper (Schinus terebinthifolia Raddi.), a species used as an alternative source of income for traditional communities and which has been arousing interest due to the consumption of its fruits as a condiment in the national and international market. This work aimed to assess the physiological quality of pink pepper seeds according to the storage period and seed size. The seeds came from a rural settlement, a pioneer in the extraction of pink pepper, in the state of Rio de Janeiro, Brazil. The seeds were evaluated for moisture content, germination, first count, length and dry weight of the germinated seedlings, during the period of time that they remained stored and the size of the seeds. The results allowed to conclude that: i) the germinative percentage of the stored pink pepper seeds decreased over the months; ii) the moisture content of the seeds decreased over the months evaluated iii) the different sizes of seeds did not show differences in germination and storage time and iv) values of length and dry weight of the seedlings did not differ according to the period of storage.

This investigation was done in the laboratory of college of agricultural engineering sciences – University of Duhok to study some wood-charcoal quality produced from some local wood species in Kurdistan region Iraq. In market, the quality of wood charcoal produced from tree species is varied due to divers’ anatomical structure and carbonizing temperature process. As a consequence, understanding the factors controlling the quality of wood charcoal is an important issue for both producers (sellers) and consumers (buyers). In most charcoal factories, wood charcoal are produced without determining of their quality whereas each quality of wood charcoal has its own properties, price and uses. The quality of charcoal made from some selected local wood species (Quercus aegilops, Salix alba, Malus domestica, and Populus alba) were evaluated. The woods species were collected from Zaxo district of Duhok province and were transformed into wood-charcoal using a steel kiln for pyrolysis. The analysis of physical and chemicals such moisture content percentage [MCP] , volatile matter percentage [VMP] , ash content percentage [ACP] and fixed carbon percentage [FCP], of the produced wood-charcoal were proximately resolved using the (ASTM D3176 – 15) method. The results showed, for the first time on all around the Kurdistan region of Iraq, the quality of wood charcoal produced from these wood species. The highest value off moisture content (2.375%) was with Malus domisteca as compared with Populus alba which was (1.000%), highest volatile matter (21.125%) was with Quercus aegilpops compared with Populus alba (4.125%), high ash content recorded (4.875%) with Quercus aegilpops compared with Salix alba (2.250%) and the fixed carbon was greater value in Populus alba which was (92.125%) compared with Quercus aegilpops (72.875%). In addition, these species present significant divergence in term of good quality of wood charcoal and the (populous alba) gave the superior quality of wood charcoal from the rest wood species. Therefore, the results of this study have a high assessment for managers of Kurdistan governmental and private charcoal factories as a suggestion which wood species is suitable in order to achieve better quality of wood charcoal.
