The present study was performed to evaluate the effects of seed priming. This was done by soaking the seeds of two rapeseed cultivars, namely, ZY15 (tolerant to low temperature and drought) and HY49 (sensitive to low temperature and drought), for 12 h in varying solutions: distilled water, 138 mg/L salicylic acid (SA), 300 mg/L gibberellic acid (GA), 89.4 mg/L sodium nitroprusside (SNP), 3000 mg/L calcium chloride (CaCl2), and 30 mg/L abscisic acid (ABA). Primed and non-primed seeds were left to germinate at 15°C and -0.15 MPa (T15W15) and at 25°C and 0 MPa (T25W0), respectively. The results showed that SA, GA, SNP, CaCl2, and ABA significantly improved the germination potential (GP), germination rate (GR), germination index (GI), stem fresh weight (SFW), stem dry weight (SDW), root length (RL), stem length (SL), and seed vigor index (SVI) under T15W15. For ZY15 seeds under T25W0, GA, SNP, CaCl2, and ABA priming reduced the average germination time (96% after 5 days) compared to that of the control (88% after 5 days). For ZY15 seeds under T15W15, SA, SNP, CaCl2, and ABA priming, with respect to the control and water-treated groups, shortened the average germination time (92% after 5 days) compared to that of the control (80% after 5 days). For HY49 seeds under T25W0, GA, SNP, CaCl2, and ABA priming reduced the average germination time (92% after 5 days) compared to that of the control (85% after 5 days). Similarly, for HY49 seeds under T15W15, GA priming shortened the average germination time (89% after 5 days) compared to that of the control (83% after 5 days). These priming agents increased the net photosynthesis, stomatal conductivity, and transpiration rate of rape seedlings under conditions of low temperature and drought stress, while also decreasing intercellular carbon dioxide (CO2) concentrations. Additionally, SA, GA, SNP, CaCl2, and ABA increased superoxide dismutase concentrations (SOD) and ascorbic peroxidase (APX) activities of rape seedlings under stress conditions, while decreasing catalase (CAT) and peroxidase (POD) activities in ZY15 seedlings. In HY49, which is sensitive to low temperature and drought, all priming solutions, except for SNP, led to an increase in SOD activity levels and a decrease in CAT activity levels. Overall, SA, GA, SNP, and CaCl2 increased the concentrations of indoleacetic acid (IAA), GA, ABA, and cytokinin (CTK) in seedlings under stress conditions. Moreover, compared to SA, CaCl2, and ABA, GA (300 mg/L) and SNP (300 mol/L) showed improved priming effects for ZY15 and HY49 under stress conditions.

The maintenance of creole seeds promotes preservation of agrobiodiversity and family autonomy. For this reason, seeds quality is essential in the context of creole seeds because directly impacts the improvement of the production field and, consequently, its continuous existence. The study evaluated the diversity and the seed quality of creole maize seeds in two harvests in the South-West of São Paulo, Brazil, an important maize production site in Brazil. Seeds from both harvests (2019 and 2020) were evaluated regarding the physical (physical aspects, one test seed mass, test of infestation), physiological (water content, germination test, seedling emergence in soil, emergence speed index and cold test) and health potential (blotter test). Among 20 lots collected, the seeds were classified into five varieties according to family famers perception. It was observed a variation in terms of physical, physiological and health quality between the seed lots. The lots harvested in 2020 had the highest values of size, 1000 seed mass, germination and vigor. The blotter test identified for both harvests, mainly in 2019, high incidence of Aspergillus sp. and Penicillium sp., considered as storage fungi. Therefore, the variation in seed quality between the harvest refers mainly to the characteristics of the storage process performed. More studies on better strategies for creole maize seed storage are necessary to guarantee seed quality, since low seed quality is a risk for losing these materials.
