Abstract:
This experiment was conducted as completely randomized design (CRD) in three replications.
Threatments was included polyethylene glycol in four levels (zero, -3, -6 and -9 bar) and priming in four levels (control, Gibberellic acid, Abscisic acid , combination of Gibberellic acid and Abscisic acid). Maximum amount of germination percent obtained in control priming treatment at -6 bar polyethylene glycol. Minimum amount of Mean Germination Time (MGT) was obtained at -6 bar polyethylene glycol thats means in this treatment the seeds germinated in short time. Coefficient germination in control priming treatment at -9 bar polyethylene glycol was in maximum amount and control priming treatment had significant different with other priming levels. Maximum seedling length was relate to control priming at zero level of polyethylene glycol and Abscisic acid at -3 bar polyethylene glycol treatments. Relative Water Content (RWC) in treatment of Abscisic acid priming at all of polyethylene glycol levels was in maximum amount in compared to other treatments. Among priming treatments, treatment with Abscisic acid caused was obtained maximum dry weight. In this plant priming by combination of Gibberellic acid and Abscisic acid to obtain the maximum germination percent is recommend.
Keywords: Abscisic acid, germination, Gibberellic acid, seedling length, dry weight
