In order to study the effects of seed hardening on the quality of seeds harvested from different positions of inflorescence on the storability of pot marigold, an experiment conducted at the University of Mohaghegh Ardabili in 2011. Seeds hardened before planting with CaCl2 2% and distilled water. At harvest, the seeds collected from both inner and outer regions of the inflorescence from storage experiments in the laboratory. Harvested seeds stored for six months at 40°C. Then an experiment conducted as factorial based on a completely randomizes design with four replications at the laboratory. Results showed that the highest germination percentage (96%), rate (3.91 day-1), radicle length (5.71 cm) and seed residual dry weight (0.061 g) were related to outer positioned seeds. The highest plumule length (4.79 cm) and seedling dry weight (0.016 g) obtained from outer seeds hardened with distilled water. In conclusion, for best stability results of pot marigold seeds, it is recommended to harden seeds before planting with water and harvest outer seeds from the inflorescence. << SP - 169 EP - 177 AU - GhaviAzm, Effat AU - Sedghi, Mohammad AU - Seyed Sharifi, Raouf AD - Department, of Agronomy and Plant Breeding, College of Agricultural Sciences, University of Mohaghegh Ardabili, Ardabili, Iran KW - Seed storage KW - Hardening KW - Pot marigold KW - Seed position on inflorescence UR - http://yujs.yu.ac.ir/jisr/article-1-184-en.html DO - 10.29252/yujs.2.2.169 ER -
