Five days after sowing (Figure 5), it is also observed, for most treatments, that the values obtained for normal seedlings were below 50%, and the seedlings were not very developed yet, while on the seventh day, in the germination tests in sand at 25, 30 and 20-30 oC and on paper at 30 and 20-30 oC, the percentage of normal seedlings was above 50%. A different behavior was observed at 20 oC, in both substrates. Some seedlings were still underdeveloped and it was difficult to classify them as normal at both 10 and 12 days after sowing.
