| ABSTRACT This study aimed to evaluate the effects of priming on seed germination under salt stress and gene expression in seeds and seedlings of P. angulata L. After priming for 10 days, seed germination was tested in plastic trays containing 15 ml of water (0 dS m-1 - control) or 15 ml of NaCl solution (2, 4, 6, 8, 10, 12, 14 and 16 dS m-1). Fresh and dry weight of shoots and roots of seedlings were evaluated at 0, 2, 4, 6, 8 dS m-1. Total RNA was extracted from whole seeds and seedlings followed by RT-qPCR. The target genes selected for this study were: ascorbate peroxidase (APX), glutathione-S-transferase (GST), thioredoxin (TXN), high affinity potassium transporter protein 1 (HAK1) and salt overly sensitive 1 (SOS1). At an electroconductivity of 14 dS... |

| To assess the germination behavior of Miconia ligustroides (DC.) Naudin, diaspores were submitted to different regimes of temperature, light and substrate. Due to intrinsic low germination of the diaspores, they were submitted to treatments that aimed to overcome endogenous and exogenous dormancy. Miconia ligustroides presents complex dormancy and to overcome it is recommended to soak the diaspores in H2SO4 diluted at 75% for 5 minutes, wash it and then soak it in a solution of 400 mg L-1 of GA3 for 12 hours. Seeding should be done on Germtest® paper at 25 °C. |

| In the last two centuries, papers have been published including measurements of the germination process. High diversity of mathematical expressions has made comparisons between papers and some times the interpretation of results difficult. Thus, in this paper is included a review about measurements of the germination process, with an analysis of the several mathematical expressions included in the specific literature, recovering the history, sense, and limitations of some germination measurements. Among the measurements included in this paper are the germinability, germination time, coefficient of uniformity of germination (CUG), coefficient of variation of the germination time (CVt), germination rate (mean rate, weighted mean rate, coefficient of... |
