“…These different germination requirements among species may play a crucial role in their establishment, growth and distribution under fluctuating salinity conditions. Temperature controlling the salinity sensitivity of seeds has been reported in (non-mangrove) halophytes (Khan and Ungar, 1985, 1996; El-Keblawy and Rawai, 2005). For example, P. juliflora germination was higher in high saline conditions at 40°C than at low temperatures (El-Keblawy and Rawai, 2005), and Huang et al .…”

Mangroves are highly adapted to extreme environmental conditions that occur at the interface of salt and fresh water. Adaptations to the saline environment during germination are a key to mangrove survival, and thereby, its distribution. The main objective of this research was to study the effect of salinity on seed germination of selected mangrove species and the application of a hydrotime model to explain the relationship between water potential of the medium and rate of seed germination. Germination of seeds was examined at 15, 25 and 35°C in light/dark over a NaCl gradient. Germination time courses were prepared, and germination data were used to investigate whether these species behave according to the principles of the hydrotime model. The model was fitted for the germination of Acanthus ilicifolius seeds at 25°C. Final germination percentage was significantly influenced by species, osmotic potential and their interaction at 25°C. Moreover, temperature had a clear effect on seed germination (Sonneratia caseolaris and Pemphis acidula) which interacted with osmotic potential. Only A. ilicifolius seeds behaved according to the hydrotime principles and thus its threshold water potential was –1.8 MPa. Optimum germination rates for seeds of the other species occurred at osmotic potentials other than 0 MPa. The descending order of salinity tolerance of the tested species was Aegiceras corniculatum > Sonneratia caseolaris > Acanthus ilicifolius > Pemphis acidula > Allophylus cobbe, suggesting that the viviparous species (A. corniculatum) is highly salt tolerant compared with the non-viviparous species. The results revealed that seeds of the study species exhibited facultative halophytic behaviour in which they can germinate over a broad range of saline environments. Use of a hydrotime model for mangroves was limited as germination of their seeds did not meet model criteria.

“…Existem algumas espécies de algaroba que conseguem tolerar níveis de salinidade acima de 18.000 mg NaCl/l, sem nenhuma redução no crescimento ou na sobrevivência, e ainda, crescerem em níveis de 36.000mg/l NaCl, o que é equivalente a água do mar (FELKER et al, 1981). A Prosopis Juliflora cresceu com sucesso em uma água de irrigação com uma condutividade elétrica de 20 dS/m na Índia (SINGH 1996) e obteve o mesmo sucesso em uma condutividade elétrica de 6-21 dS/m no Paquistão (KHAN et al, 1986).…”

AGROPECUÁRIA NO SEMIÁRIDO

A algaroba (Prosopis sp) foi trazida para o Semiárido Brasileiro como o objetivo de alimentar os rebanhos nos períodos mais secos do ano. Com o objetivo de avaliar parâmetros químicos em solos cultivados com esta cultura, foi conduzido um experimento junto à área experimental do Departamento de Engenharia, UFCG, Universidade Federal de Campina Grande, Estado da Paraíba. No experimento foi utilizado um delineamento estatístico casualizado, com um esquema fatorial de 5 x 2, com 4 repetições, com 5 níveis de reposição de água (W1= 20% até W5 = 100% da evapotranspiração) e 2 tipos de solo. Em 92,5% dos lisímetros as análises mostraram que houve um aumento da fixação no nível de nitrogênio no solo. Já com relação ao teor de matéria orgânica os resultados que foram encontrados no experimento, mostraram que 95% dos lisímetros apresentaram um acréscimo no valor da percentagem de matéria orgânica, quando comparados com os resultados obtidos no inicio do experimento. Com os resultados obtidos ao final do experimento constatamos que a algaroba trouxe benefícios no tocante à melhoria na qualidade do solo.
