Regarding emergence speed index, the best treatments were lopping, hot water immersion for 1,2,3,4,5 and 6 min as well as treatment with sulfuric acid for 10 min and sandpaper, with no considerable differences between treatments, while the other treatments provided inferior results (Figure 2B).

Regarding the percentage of germination, it was found that the paper roll was statistically superior to other substrates, whereas sand and vermiculite substrates resulted in lower germination rates, irrespective of temperature.

In the treatment with sulfuric acid (P.A 98%), seeds were placed in a beaker, covered with acid and frequently shaken with a glass rod. After each test period, contents were put into a plastic sieve with seeds rinsed in running water to eliminate acid waste and placed to dry on paper towels at room temperature.” (p. 14)

Within the treatment with hot water, seeds were placed in a beaker and immersed in water. After each period, the disposal of water was similar to that in the acid sulfuric treatment.” (p. 14)

For mechanical scarification, seeds were manually rubbed with sandpaper No 80 until visible tegument weathering.” (p. 14)

For seed lopping, to made a small cut into the opposite site of the micropyle, using scissors.” (p. 14)

In the second experiment, germination in paper (sterilised at 105 °C for two hours), vermiculite and sand (sterilised at 120 °C for two hours) was evaluated. In addition, we disinfected seeds using 0.5% sodium hypochlorite for 2 min and subsequently washed them with distilled water.” (p. 15)

The four tested substrates were sand, paper, paper roll and vermiculite, using six temperatures, 20, 25, 30, 35 and 40 °C, and alternating 20-30 °C. We used 197 g of sand per plastic box (“gerbox” type, 11 x 11 x 3 cm), moistened with 37 mL of distilled water (60% of field capacity). For sowing “on paper”, two sheets of blotting paper were used, arranged in a “gerbox” and moistened with a quantity of water equal to 2.5 times the dry weight of the paper. For germination on paper rolls, we used three sheets of “germitest” also moistened with a quantity of water equal to 2.5 times the dry weight of the paper. Vermiculite of medium grain size was moistened with an amount of water equal to 2.0 times its dry weight (BRASIL, 2013).” (p. 15)

Immersion in hot water for 1, 2, 3, 4, 5 and 6 minutes, sulfuric acid treatment for 10 and 13 minutes, sandpaper and lopping are the most suitable treatments for overcoming dormancy in seeds of M. tenuiflora.” (p. 20)

In addition, seed germination of M. Tenuiflora should be carried out at 25 °C using on paper rolls as substrate.” (p. 20)

In all substrates, a temperature of 40 °C resulted in a higher percentage of dead seeds (Table 2).” (p. 20)
