Cross-Tolerance Mechanism Induction in Melon Seeds by Priming Prior Drying

Abstract: The loss of benefits after re-drying is one of the drawbacks of the seed priming technique. Different types of stresses have been used before re-drying to preserve the priming benefits. This process may be seen as promoting cross tolerance to increase the defense mechanisms that prevent loss of viability in seeds primed after drying. We tested the effect of some stresses to induce cross-tolerance and different drying conditions with the aim of maintaining priming benefits in melon seeds. The seeds were primed … Show more

“…Em temperaturas mais baixas é observado aumento nos níveis de giberelina (GA) (Penfield et al 2005, Toh et al 2008, no entanto, até certo ponto, devido a redução na atividade das enzimas envolvidas na síntese hormonal. O desencadeamento de mecanismos associados ao estresse e o ABA pode levar ao aumento da síntese das moléculas antioxidantes, reduzindo a atividade da enzima catalase e consecutivamente melhorando o desempenho da germinação da semente (Lira et al 2015). Chandel et al (1995) observou numerosos ribossomos no citoplasma das sementes de cacaueiro, indicando alta atividade metabólica.…”

“…This technique stimulates pregermination metabolic processes, increases the antioxidant system activity and the repair of membranes (Masondo et al 2018) under abiotic stress. Under conditions of heat stress, seed priming was effective on melon (Lira et al 2015), onion (Murili et al 2016), pepper (Alqui et al 2014), spinach (Ziaf et al 2017) and other crops.…”

“…Watermelon and melon have low germination and growth rates at both low (below 13°C) and high (above 40°C) temperatures, which creates problems for melon cultivation in northwestern and southern Brazil (Kozik and Wehner, 2014;Lira et al, 2015). These temperature effects can affect germination, seedling emergence and vigor in the cucurbits species.…”
