Caracterización física ex-situ de Chamaedorea metallica como recurso forestal no maderable

Seed quality analysis determines factors that can affect a seed lot or samples. The aim of the studio was determine physical qualityof a lot of seeds of the Chamaedorea metallica collected in two fruiting periods; March to September 2018 and February to April2019; They were collected from mother plants of Chamaedorea metallica in the Ye`tsil garden at the Technological Institute of theValley of Oaxaca. The fruits presented purple-purple coloration in the exocarp; they were cleaning process to obtain the seeds,which consisted of soaking the fruits in water for 48 hours, they washed with running water until the mesocarp was completelydetached. The seeds dried under shade for five days on bond paper. The analysis carried out according to the minimum parametersmentioned by the International Seed Testing Association (ISTA). Data of percentage of purity, weight, number of seeds per kgandmoisture content obtained. The data from the physical analysis differed in both years, obtaining the best results in moisture contentand weight in the seeds collected in 2019. We concluded that the seeds of the mother plants of Chamaedorea metallica are of goodquality; that the collection period and the time of the fruit on the plant influence their quality.
