摘要

This study was conducted with the aim of choosing the most suitable carbon nanotube treatment under drought stress conditions on two maize (Zea mays L.) hybrids. The results of variance analysis indicated that most of the hybrids had significant differences in most of the studied traits. The effect of carbon nanotubes and the effect of drought also showed significant differences in all traits. Based on the drawn polygon diagram, Fajr hybrid with treatments G1N1C1, G1N0D2 and G1N2D1 were identified as the desired treatments. Dehghan's hybrid with treatments G2N2C, G2N0C, G2N0D2 and G2N2D2 were more favorable than other treatments examined in the experiment. According to the ranking diagram of the treatments in terms of all traits, Dehghan hybrid with pretreatment with carbon nanotubes 50 mg/L and without pretreatment with carbon nanotubes in normal humidity conditions were more desirable. Based on the ideal treatment ranking diagram, the Dehghan hybrid with 50 mg/L carbon nanotube pretreatment under normal conditions and the Fajr hybrid with 25 mg/L carbon nanotube pretreatment under normal conditions were identified as the most promising treatments. The treatment grouping chart also grouped the treatments into 9 groups based on the reaction to the traits. Based on principal components analysis, five components explained more than 92% of the variance of the total data. The correlation analysis revealed a positive correlation between most traits, as confirmed by the correlation graph. In general, it can be concluded that the effect of carbon nanotubes in normal humidity conditions has the most positive effect on the performance of traits, and Fajr hybrid with carbon nanotube pretreatment of 25 mg/liter in normal conditions and Dehghan hybrid without pretreatment and with the pretreatment of carbon nanotubes 50 mg/liter in normal conditions had more efficiency than other treatments.
