Tolerance of melon cultivars to irrigation water salinity

Abstract: A B S T R A C TThe use of saline water for irrigation causes severe restriction to nutritional balance, growth and production in many crops due to the effect of salts on plant and soil. The objective of this study was to investigate the response of melon (Cucumis melo L.) cultivars to various levels of irrigation water salinity on yield and fruit quality. A field experiment was conducted in a split-plot randomized block design with four replicates. The factors were five levels of irrigation water salinity (0.5… Show more

“…The increase of the biomass allocation in the "hard" jackfruit ( Figure 2B), may be an adaptation to the saline conditions imposed, since there is variability between varieties of the same species (PEREIRA et al, 2017;SÁ et al, 2017). As a defense mechanism, some varieties maintain high levels of potassium (K + ) and calcium (Ca 2+ ) and low sodium content (Na + ) in its tissues, thus absorbing higher amounts of K + + and Ca +2 , in order to maintain high K + /Na + and Ca 2+ /Na + ratios, so their biomass are not reduced even under saline conditions (GALDINO et al, 2017).…”

“…Observa-se que houve efeito interativo para variedades x salinidade da água x adubação no crescimento vegetativo do feijão-fava, demonstrando que ambos os fatores interferem simultaneamente nessa cultura. Alguns autores observaram efeitos interativos entre estes fatores em diversas espécies como Cucumis melo (PEREIRA et al, 2017;LOPES et al;2017), Cucurbita sp (SANTOS et al, 2018), Carica papaya (LIMA NETO et al, 2016) e Phaseolus Lunatus (NASCIMENTO et al, 2017 ................................... g k -1................................... .......................... g cm -3................................. m No que se refere ao comprimento do ramo (Figura 1) verificou-se que a variedade Raio-desol (V 2 ), apresentou maior comprimento se comparado às variedades Lavandeira (V 1 ) e a Rajada (V 3 ). Este comportamento pode está relacionado à capacidade genética da variedade de se desenvolver ou pela tolerância a salinidade, o que torna uma opção viável de cultivo, uma vez que o semiárido paraibano apresenta solos excessivamente salinos (PASSOS et al, 2010;ARANTES et al, 2016).…”

“…A redução observada quando a fava foi cultivada na salinidade máxima da água de irrigação, independentemente das doses de adubo orgânico, pode se justificar segundo Pereira et al (2017) ao excesso de sais ocasionar efeitos tóxicos devido ao acúmulo de íons, onde essa toxicidade de íons, durante o processo de germinação e desenvolvimento da planta, causa diversos distúrbios fisiológicos e bioquímicos, como o desequilíbrio hormonal e a redução do uso de reservas.…”

“…Consequently, studies that make possible the selection of cultivars adapted to salinity are important (Medeiros et al 2014, Araújo et al 2016, Pereira et al 2017, but those that approach the influence of salinity on the physiological mechanisms involved with the photosynthetic efficiency related to the variability of melon cultivars are rare, as the study of Akrami & Arzani (2018), who analyzed the salinity interference on the physiology of 17 melon cultivars, observing a genotypic variation for all the physiological characteristics and concluding that the Sabouni and Shahabadi-1 cultivars are more tolerant.…”
