Effect of seed priming on physiological and germination characteristics of deteriorated seed of squash (Cucurbita pepo L. var. styrica) under salinity stress
In order to investigate the effect of priming on different aspects of germination of aged pumpkin seeds under drought stress, a factorial experiment was conducted based on a completely randomized design with four replications in the laboratory. Treatments included different levels of aging (control,...

| description | In order to investigate the effect of priming on different aspects of germination of aged pumpkin seeds under drought stress, a factorial experiment was conducted based on a completely randomized design with four replications in the laboratory. Treatments included different levels of aging (control, 85% and 75% of control germination), salt stress (0, 75 and 150 Mmol) and priming (control, hydro, gibberellin, GR24, benzyl aminopurine and spermidine). The seeds reached the desired vigor level by accelerated ageing test. Morphological traits were also studied using seedling growth test. Mobility of seed lipid reserves, carbohydrate, number of photosynthetic pigments, photosynthesis, α-amylase and the amount of sodium ions were measured. In the study of germination traits, motility of lipid reserves, carbohydrates, chlorophyll a, photosynthesis and sodium content, salinity stress, seed deterioration and priming led to a significant change in them compared to the control seed. While in the case of shoot and root dry weight, chlorophyll b, and chlorophyll a / b ratio under salinity, seed deterioration and priming, no statistically significant change were compared to the control seed, the greatest effect of gibberellin-related seed priming was observed on germination traits and spermidine on physiological traits. |
