Abstract :The aim of study was to investigate the effects of salicylic acid on germination and seedling parameters of maize cultivars insert ignore into journalissuearticles values(Zea mays L.); under drought stress conditions. The research was carried out in a growth chamber in a factorial experiment design with four replications in random plots. In this study, three different silage maize cultivars were used insert ignore into journalissuearticles values(Side, Pehlivan and Burak);. Drought conditions were established using Polyethylene glycol-6000 insert ignore into journalissuearticles values(PEG-6000); at three different levels insert ignore into journalissuearticles values(0.-0.4 MPa and -0.8 MPa);. Salicylic acid applications were calculated at three different doses of 0-0.1-0.2 mM. The parameters examined in Side cultivar gave superior results exposed to drought conditions compared to other cultivars. Differences were determined in the response of maize cultivars to drought stress, and statistically noteworthy diminishes were also observed as the drought level enhanced. It was displayed that salicylic acid applications generally boosted germination and seedling parameters exposed to drought conditions compared to control. The maximum shoot lenght was detected at 0.2 mM SA dose with 2.30 cm but that did not exhibit significant numerical differences. SA applications, on the other hand, did not have an effect on root length. Moreover, the best result of shoot fresh weight was recorded in 0.1 mM SA application, as root fresh weight gave the best in 0.2 mM SA application. Furthermore, when a correlation is made between the specified parameters, the highest relation was markedly positive and linked between GR and GI insert ignore into journalissuearticles values(r: 0.99, p<0.01);. In this study, it was found that the growth deficiency that may occur under drought stress conditions that maize seeds may encounter during the germination period can be reduced and even improved by salicylic acid applications.
