Figure 1. Tray with seeds over mesh wire to perform the Accelerated Aging Test.
Table 1. Percentage of normal seedlings, germination velocity index (GVI), and mean time of maximum germination (MTMG) after three days of accelerated aging (3d-aging) at 44°C and 100% relative humidity, for different weight ranges of J. nigra seeds.
Figure 2. Dark stains around the embryo of non-germinated seeds from the 3-day accelerated aging treatment (44ºC ± 1ºC; 100% relative humidity).
Figure 3. Non-turgid and decayed tissues in non-germinated seeds of weight range 1 (a) and 2 (b) after 7 and 15 days of accelerated aging (44ºC ± 1ºC; 100% relative humidity).
Figure 4. Deficiencies of normal weak seedlings. (a): vigorous primary root, weak secondary roots, damaged terminal bud, and necrosis in some axillary buds. (b): vigorous primary and secondary roots, healthy terminal bud and necrosis in axillary buds.
Figure 5. Deficiencies of abnormal seedlings. (a): stubby primary root with no secondary roots. (b): absent or damaged primary root with necrosis in secondary roots and in primary leaves. (c): vigorous primary root, weak secondary roots, and damaged terminal bud.
