“…At 60 DAS, measurements of the stem diameter were made at 5 cm from the soil with a digital caliper, the count of leaves and leaf area of all the seedlings was estimated by the product between length and greater width, then the correction was carried out by multiplying each value by factor 0.72 suggested by Cavalcante et al (2002) for yellow passion fruit seedlings.The dry matter of the roots and shoot of the seedlings was obtained after drying the material in oven at 65 °C and weighing in a precision analytical balance. At the same age, the chlorophyll a and b indexes were measured directly on the top, middle and end of the third leaf of each seedling by the non-destructive method using the chlorophyll meter, ClorofiLOG ® model CFL1030.…”

“…The marginal effects of salinity act during all phases of the plants (Cavalcante et al, 2002). However, the first contact between the saline environment and the seedlings begins during the growth of the embryonic axis of the seed, and this can almost always compromise the germination process that constitutes the most important phase for the evaluation of the behavior of a given culture to the salinity (Nascimento et al, 2012).…”

“…Informações dessa natureza podem ser úteis aos produtores de mudas em áreas onde a água seja de qualidade restritiva à agricultura. Entretanto, Soares et al (2002), Cavalcante et al (2005) e Macedo et al (2006) após cultivarem o maracujazeiro-amarelo no campo, irrigado com águas de condutividade elétrica 3,6 dS m -1 , 1,5 e 2,0 dS m -1 e, 3,2 dS m -1 , constataram que a cultura se comportou, em termos de produtividade, como moderadamente tolerante à salinidade.…”

“…Apesar dos riscos mencionados, Rhoades et al (2000), Cavalcante et al (2005), e Malash et al (2005) apresentam dados promissores da utilização de águas salinas, oriundas de mananciais e de reutilização da água de drenagem para produção agrícola, em vários países do mundo. Nos Estados Unidos da América do Norte, foram produzidos alfafa, algodão, plantas forrageiras, milho e sorgo irrigados com águas de salinidade variando de 5 a 8 dS m -1 .…”

“…A goiabeira (Psidium guajava L.) é uma das fruteiras que vem sendo cultivada com sucesso sob irrigação no Nordeste Brasileiro (Gonzaga Neto et al, 2007), devido a adaptação às condições edafoclimáticas e a grande aceitação de seu fruto nos mercados interno e externo (Cavalcante et al, 2005).…”
