“…The reductions in phytomass accumulation of fruit crops under salt stress conditions also corroborate the results observed by Nobre et al (2003), Brito et al (2008), Silva & Amorim (2009), Sousa et al (2011, Souto et al (2013) and Sá et al (2013) in the production of soursop rootstocks, citrus, 'umbu' seedlings, dwarf cashew, noni and papaya, respectively.…”

“…Data referring to guava emergence under saline conditions are scarce in the literature, but reductions in the emergence of fruit crops such as guava (Nobre et al, 2003), dwarf cashew (Sousa et al, 2011) and papaya (Sá et al, 2013) have been observed under salt stress conditions. These authors explain that the reduction in emergence is directly related to the reduction in the osmotic potential, which affects seed imbibition, consequently decreasing the number of emerged plantlets, causing a non-uniform stand.…”

“…It is believed that the increase of sodium salts in the substrate caused toxicity to the guava rootstocks, affecting their physiological quality and compromising the absorption of water and nutrients, due to the reduction of the osmotic potential of the substrate and the competition between specific ions, leading to disorders in plant growth (Brito et al, 2008;Sousa et al, 2011;Sá et al, 2013;Taiz & Zeiger, 2013). SD and NL decreased with the increase in salinity.…”

A B S T R A C TThis study aimed to evaluate the tolerance of guava rootstocks under salt stress in the initial development stage. The experiment was conducted in a greenhouse in a randomized block design in a 5 x 3 factorial, consisting of five levels of irrigation water salinity (0.6, 1.2, 1.8, 2.4 and 3.0 dS m -1 ) and three guava rootstocks ('Crioula' , 'Paluma' and 'Ogawa'), with four replicates and four plants per replicate. Emergence, growth and phytomass accumulation were evaluated 30 days after sowing. Increased salinity restricts guava emergence, growth and phytomass accumulation, and the most drastic effects occur at levels higher than 1.8 dS m -1 . The cultivar 'Crioula' is more tolerant to salinity in relation to 'Paluma' and 'Ogawa' , and can be indicated as rootstock.Tolerância de porta-enxertos de goiabeira ao estresse salino R E S U M O Objetivou-se, com este trabalho, avaliar a tolerância de porta-enxertos de goiabeira sob estresse salino na fase inicial de desenvolvimento. O experimento foi conduzido em casa de vegetação em delineamento experimental em blocos casualizados, no esquema fatorial 5 x 3, constituído de cinco níveis de salinidade da água de irrigação (0,6; 1,2; 1,8; 2,4 e 3,0 dS m -1 ) e três porta-enxertos de goiabeira (Crioula, Paluma e Ogawa), com quatro repetições e quatro plantas por repetição. Após 30 dias da semeadura foram avaliados a emergência, o crescimento e o acúmulo de fitomassa. O aumento da salinidade restringe a emergência, o crescimento e o acúmulo de fitomassa da goiabeira sendo os efeitos mais drásticos em níveis superiores a 1,8 dS m -1 . A cultivar Crioula é mais tolerante à salinidade em relação às cultivares Paluma e Ogawa, podendo ser indicada como porta-enxerto.

Due to the reduced availability of good-quality water in the semi-arid region of Northeast Brazil, the utilization of saline waters in irrigation became an alternative for the expansion of agriculture in this region. Thus, it is necessary to develop techniques which can make viable the use of these waters in agriculture. Given the above, this study aimed to evaluate the morphophysiology of 'FAGA 11' cashew rootstock subjected to different levels of irrigation water salinity and exogenous proline application through the leaves. The experiment was carried out in a greenhouse of the Federal University of Campina Grande, at the Center of Sciences and Agri-Food Technology, Campus of Pombal, PB, Brazil, in a randomized block design, in 5 × 4 factorial scheme, with three replicates and two plants per plot. Treatments consisted of different levels of irrigation water electrical conductivity-ECw (0.3; 1.0; 1.7; 2.4 and 3.1 dS m -1 ) combined with proline concentrations applied through the leaves-PC (0; 4; 8 and 12 mM). Irrigations with water up to ECw of 1.37 dS m -1 may be used as it causes an acceptable 10% reduction in the variables of morphology of cashew FAGA 11 seedlings. The proline concentrations tested, with the exception of the Dickson's quality index of seedlings, did not attenuate the deleterious effects of irrigation water salinity on the cashew FAGA 11 rootstock seedlings.
