Crescimento Inicial E Tolerância De Cultivares De Pepino Sob Estresse Salino

Abstract: RESUMOO pepino é uma hortaliça de grande importância econômica e alimentar, devido a sua apreciação como componente de saladas. No entanto, o seu cultivo no semiárido apresenta risco, devido aos problemas de salinidade, sendo necessária a identificação de cultivares tolerantes, que se desenvolvam melhor em ambientes com problemas de salinidade. Com isso, Objetivou-se avaliar a emergência, o crescimento e a tolerância de cultivares de pepino ao estresse salino. O experimento foi desenvolvido em ambiente protegi… Show more

“…The observed results corroborate those of Sales et al (2015), Oliveira et al (2015a) and Albuquerque et al (2016), who evaluated emergence and initial growth of seedlings of coriander, beet and cucumber, respectively, under different levels of irrigation water salinity. These authors pointed out that the excessive increase in the salinity of the substrate, due to the saline irrigation water, directly affects the physiological responses of the seeds, besides causing hormonal disorders in young plants; thus, leading to reductions in emergence and initial growth of the plants.…”

“…The reduction in phytomass accumulation as a function of the increase in irrigation water salinity was also observed in the coriander crop by Oliveira et al (2010) and Rebouças et al (2013), as well as in other vegetables: lettuce (Oliveira et al, 2011); broccoli (Maciel et al, 2012); pumpkin (Oliveira et al, 2014); cabbage (Oliveira et al, 2015b); melon , cucumber (Albuquerque et al, 2016) and eggplant . The results observed in the salinity tolerance index confirm the results observed for emergence, growth and phytomass accumulation, with linear reductions in the tolerance as irrigation water salinity increased ( Figure 1H).…”

(Silva et al, 2016). Toxic concentrations of these ions (Na + , K + , Ca 2+ , Mg 2+ ) affect other physiological and metabolic processes of embryonic tissues, including cellular division and differentiation, enzyme activity, and the uptake and distribution of nutrients.…”

“…Na cultivar de girassol, Rabbani et al (2013) e Lewandoski et al, (2016) também constataram um aumento no TMG à medida em que os níveis de sais foram elevados, onde o maior tempo de germinação observado, foi para a concentração de 250 Mol.m -3 (5 dias) e o menor para a testemunha (3 dias). Albuquerque et al (2016) também observaram um aumento no TMG de sementes de pepino submetidas a salinidade.…”
