TABLE 1 in Do spores of Tortula inermis (Brid.) Mont. deharden to desiccation tolerance during germination?

TABLE 1. — The effects of dehardening on 13-year-old Tortula inermis (Brid.) Mont. spores, using germination levels and abortive spore frequency. Dehardening consisted of rehydrating spores for 0, 3, 6, 12, 24, 36, and 48 h followed by a rapid drying to equilibration with c. 34% relative humidity at c. 23°C, and then rehydrating and assessing germination on days 3, 7, and 14 postrehydration.Abbreviations: GP, germination percentage; N, number of spores assessed, mean± one S.E., N= 600 spores for day 14 postrehydration germination percentage and abortive spore counts.
