Table 2 Germination percentages of the different pretreatments. M1: Sebkhet Cherita; M2: Agareb coast; M3: Kraten; M4: Tinto River estuary; M5: Rábida; M6: San Juan del Puerto. SD: standard deviation. (-) no data. Values are means ± SD (n = 4). d: days (pretreatment duration). The asterisk indicates means within an analyzed variable that is significantly different from the corresponding control treatment (t-Student; level of significance (p < 0.05))
From: Seed priming to optimize germination in Arthrocnemum Moq.
