To alleviate high-temperature-induced reductions in seed germination, emergence, and seedling uniformity in celery (Apium graveolens L.), seeds were primed via solid matrix priming (SMP); 0.5 g celery seeds was incubated at 15C with 10 g calcined clay and 2 ml water. After 2 days, 1, 2, 3, or 4 ml water or 1% NaOCl solution was added and seeds were kept for 2, 4, 6, 8, 10, 12, and 14 additional days. The germination percentage and coefficient of germination velocity (COV) were calculated for each treatment at 15 and 30C. The seeds primed with NaOCl gained significantly less moisture after 8 days of priming than those treated with water, regardless of the volume added. Germination of nonprimed seeds was 83% and 2% at 15 and 30C, respectively. Final germination at 30C increased to >80% when seeds were primed with 3 or 4 ml NaOCl solution or 3 ml water for >10 days. SMP treatment significantly reduced the negative effect of high temperature on celery seed germination.

Extract of celery ( Apium graveolens L.) seeds was investigated against phytopathogenic fungi. The light petroleum extract showed promising inhibition activities in the tests against Rhizoctonia solani and Fusarium oxysporum f. sp. vasinfecum. Chromatographic separation of the extract gave 19 fractions, one of which, QCZ-4, possessed significant inhibitory rates of 64.6%, 88.4% and 54.7% at a concentration of 100 ppm against R. solani, F. oxysporium f. sp. vasinfecum and Alternaria alternata, respectively. Major components in the active fraction were identified by GC-MS as p-(2-aminoethyl)phenol (39.7%), 3-(3,4-dimethybenzoyl) propionic acid (32.6%) and p-heptylphenol (26.9%).

The high temperature severely reduces seed germination, emergence, and seedling uniformity in celery (Apium graveolens L.). Celery seeds were primed via solid matrix priming (SMP) using water or 1% sodium hypochlorite (NaOCl) solution at 1, 2, 3 or 4 ml rate for 2, 4, 6, 8, 10, 12 and 14 days. Moisture content of the seeds was calculated for each priming treatment and time interval. After priming, the seeds were dried back to the original dry weight. The germination percentage was calculated for each treatment at two different temperatures (15 and 30C). The seed primed with NaOCl gained significantly less moisture during priming than the water treatment. Seeds primed with NaOCl had significantly greater germination at both 15 and 30C, compared to seeds primed with water. The germination percentage of non-primed seeds was 83% and 2% at 15C and 30C, respectively. The final germination percentage at 30C was increase to 85% when the seeds were primed with 3 ml of NaOCl for 14 days. The combination of SMP with NaOCl significantly reduced the negative effect of high temperature on celery seed germination.
