“…Dantas et al (2014) verified that germination of Aspidosperma pyrifolium seeds was not affected by NaCl solutions above -0.36 MPa, however, GSI was reduced. Similar results were also observed in Piptadenia moniliformis seeds at 25 and 30 °C, where germination did not differ when subjected to an osmotic potential of up to -0.6 MPa, however, GSI decreased (Pereira et al 2016). In the present study, the germination of E. urophylla, E. tereticornis, E. grandis, E. saligna and E. camaldulensis was not affected at -0.5 MPa, but their GSI was reduced.…”

Seed plays a key role in the propagation of Eucalyptus, allowing greater distribution and adaptation of the material under different soil and weather conditions. Since water and salt stress are the main factors that affect plant development, studying their effect on germination and initial growth of seedlings of these species is relevant. In order to determine the species with the most contrasting behavior, to tolerate water and salt stress, germination tests at different osmotic potentials, obtained by aqueous solutions of polyethylene glycol and NaCl, were performed to simulate water and salt stress. Radicle protrusion was counted daily while normal seedlings were counted at the end of the tests (45 days). Generalised linear model analysis was used and the data were analysed by the LSD test at 5% probability. It was verified that the maximum limit of tolerance to water stress ranged from-0.6 to-0.8 MPa for the six studied species. Eucalyptus urophylla and E. tereticornis were more tolerant to drought while E. camaldulensis and E. tereticornis were the most tolerant to salt stress during germination.

“…This result assures the advantages of determining the quality of seeds by accelerated aging test. Pereira et al (2016) evaluated the effects of saline and temperature stress on germination and vigor of Piptadenia moniliformis (a species known in Brazil as "catanduva") seeds, verified in terms of germination percentage and germination speed index, seedling (root and shoot) length, and total dry matter.

Objective of this study was to evaluate the potential physiologic potential of seeds of four tropical forage legumes submitted to the permanence in mineral mixture for bovine, for the germination test, for the accelerated aging test and for the electric conductivity test, with the intention of dispersing them in the pasture by the bovine feces. A completely randomized design at factorial scheme 4x7 (four species, seven treatments) with four repetitions was used. The seeds stayed in the mineral mixture for: 0, 12, 24, 36, 48, 72 and 96 hours. The saline stress, up to 24 hours, did not represent risk for the germination of the seeds. Like this, the introduction of seeds in mineral mixture for bovines for dispersion of legumes in the pasture can used. Resumo Potencial fisiológico de sementes de leguminosas submetidas à permanência em mistura mineralObjetivou-se com estudo avaliar o potencial fisiológico de sementes de quatro leguminosas forrageiras tropicais submetidas à permanência em mistura mineral para bovinos, pelo teste de germinação, pelo teste de envelhecimento acelerado e pelo teste de condutividade elétrica, com o intuito de dispersá-las na pastagem pelas fezes bovinas. O delineamento experimental foi inteiramente casualizado em esquema fatorial 4x7 (quatro espécies, sete tratamentos), com quatro repetições. As sementes permaneceram na mistura mineral por: 0, 12, 24, 36, 48, 72 e 96 horas. O estresse salino, até 24 horas, não representou risco para a germinação das sementes. Assim, a introdução de sementes em mistura mineral para bovinos para a dispersão de leguminosas na pastagem pode ser utilizada.Palavras chave: Suplemento mineral; germinação; teor de umidade e vigor.

O objetivo do presente trabalho foi avaliar o efeito do estresse salino na germinação e crescimento inicial de canafístula (Peltophorum dubium (Sprengel) Taubert), tamboril (Enterolobium contortisiliquum (Vell.) Morong.) e pau-formiga (Triplaris americana L.), além de determinar a máxima tolerância das três espécies arbóreas florestais à presença de NaCl na solução de embebição. Foi adotado delineamento experimental inteiramente casualizado, com quatro repetições de 50 sementes, no esquema fatorial 3 x 5, sendo estudada a resposta das três espécies a cinco níveis de potencial osmótico (0; -0,3; -0,6; -1,2 e -1,8 MPa), por simulação de estresse salino com NaCl. Aos 28 dias após semeadura foram avaliados: percentagem de germinação; índice de velocidade de germinação (IVG); tempo médio de germinação; comprimento da maior raiz; massa seca da parte aérea, raízes e total. A germinação e o crescimento inicial de plântulas de tamboril e canafístula foram afetados negativamente pelo aumento da concentração salina do meio. Pau-formiga mostrou-se mais tolerante ao estresse salino, apresentando elevação dos valores médios de percentagem de germinação, IVG, comprimento da maior raiz e produção de massa seca total em potenciais osmóticos variando de -0,81 a -1,15 Mpa. Os maiores valores médios de produção de massa seca da parte aérea, raízes e total foram observados em plântulas de tamboril.
