Abstract
A pot experiment was conducted to investigate the effect of priming with the extract of plant Calotropis procera on seed germination of Sorghum bicolor. The seeds of Sorghum bicolor were primed with different concentrations of Calotropis procera leaf extract and milky sap exudate for five days at different time intervals. In total, there were five groups of days and nine seed priming treatments. The result showed that maximum seeds were germinated on day 4 in all treatments, but it was not significantly different from day 2, 3, and day 5. Whereas the highest germination of seeds was noted in two treatments, 24 hours priming with 100% boiled leaves extract (T3) and 24 hours priming with 100% milky exudate (T4), irrespective of priming days, except one day. These results showed that both milky exudate and boiled leaf extract have a positive effect on seed germination of Sorghum bicolor; therefore, in the future, both types of extracts of Calotropis procera should be considered important for priming the seeds of different plants to improve seed germination.
