In order to conserve the diversity of traditional plants that communities use, and ensure the next harvest of their crops, their local seeds need to be stored using methods that ensure the viability of the seeds. In this research, the effect of two types of storage ((hermetic glass jar, aluminum bag vacuum- sealed) at two storage times (1 to 3 months) and three storage temperatures (-20, 5, 20 °C) on the germination of seeds of the species Coriandrum sativum, Eryngium foetidum and Plantago major, is evaluated using the analysis of generalized linear models (GLM). In addition, germination percentages (G), synchrony index (Z) and germination rate coefficient (VG) are calculated. It is found that the germination percentages of seeds stored during one and three months are similar in all treatments at month 0. None of the storage temperatures significantly affected seed germination in the three species during the storage months. There are no significant differences in the germination of seeds stored in hermetic glass jar or in aluminium bags. Seed germination synchrony index (Z) of the three species increases after storage for one and three months compared to month 0. Germination rate doubles in P. major and E. foetidum and is similar to month 0 in C. sativum. The VG and Z indices show that the germination of the species, after 1 and 3 months of storage at the three temperature levels, is short-term and uniform, in addition, they do not have latency and have orthodox behavior. This is an advantage for farmers because it allows the seeds to be stored for a period of time and the quick and uniform establishment of the individuals. In the short term, storage in a sealed glass bottle and at cool temperatures (i. e. 5, 20 °C) is an option available to farmers to maintain the viability of the seeds.
