SD (standard deviation); CV (coefficient of variation); GR (germination rate), SL (seedling length) and FW (fresh weight); rGR (relative germination rate), rSL (relative seedling length) and rFW (relative fresh weight). Artificial aging includes both treatment and relative trait values, whereas natural aging includes only treatment trait value (no control was used in natural aging). * &** represent significance at 5 and 1% probability levels, respectively
