Effect of Salicylic Acid on the Physiological Quality of Salt-Stressed Cucumis melo Seeds

Abstract

Aim:The aim of this study was to evaluate the physiological quality of seeds of two melon varieties (Cucumis melo) in response to saline stress and salicylic acid treatment. Study Design: The experimental design was a completely randomized design with five different water salinities and five doses of salicylic acid, with four replicates of 50 seeds. Place and Duration of Study: The experiment was carried out in the Laboratory of Seed Analysis, located in the Center of Agricultural Sciences of the Federal University of Paraíba, Areia-PB, Brazil. Methodology: The experiment was conducted with two varieties of melon (Cantalupensis and Eldorado 300). Creole melon seeds (cucumber melon -Cantalupensis) were extracted from Original Research Article

Ácido salicílico atenua o efeito do estresse hídrico na germinação e crescimento inicial de plântulas de <i>Cereus jamacaru</i> DC

“…A indução de resistência a condições de estresse promovida pela embebição de sementes com ácido salicílico foi relatada por outros autores, como em melão (Cucumis melo L.) por [23] O vigor das sementes, avaliado pelo índice de velocidade de germinação, indica que a dose de 0,29 mM L -1 de AS estimulou uma maior (5,29) rapidez no processo de germinação das sementes submetidas ao tratamento controle de 0,0 MPa (Figura 1C). Salienta-se que a aplicação da dose de 1,0 mM L -1 de AS atenuou o efeito do déficit hídrico até o potencial de -0,36 MPa, decrescendo à medida que o potencial foi reduzido.…”

Effects of irrigation water salinity and salicylic acid on germination and vigor of Mesosphaerum suaveolens (L.) Kuntze

“…The values increased from 5.2 to 6.3 cm with a 21.2% superiority between seedlings without and with 2.0 mM of SA. The positive action of SA in plant growth regulation is due to the stimulation of cell expansion and division in different phases (Ghassemi-Golezani & Farhangi-Abriz, 2018;Nóbrega et al, 2018a). value of 11.8, inducing an increase of 93.4% with a dose of 2 mM.…”
