The experiment was laid down in completely randomize design with four replications. In this research eight priming sources i.e. NaCl, CaCl2, KCl, KNO3, NH4Cl, Na2SO4, PEG and Manitol along with seed soaking in water and control were tested on sorghum seed germinated in laboratory to test germination % and the effect of osmopriming on germination of sorghum seed in incubator at room temperature after 24 hour priming. The data was recorded on germination % in incubator and at room temperature and root length (cm). Statistical analysis of the data revealed that germination % and root length were significantly affected by osmopriming sources and levels. Mean values showed that maximum germination (94 %) for PEG 8000, root length (7.02 cm) for NaCl. Among chemicals CaCl2 showed higher germination. Similarly NaCl and PEG 800 were also better than other chemical sources. KNO3 showed very poor performance among all chemicals. The lower levels of most chemicals performed better than higher levels. It was concluded that soaking seed with osmopriming agents in low concentrations enhances germination and rapid seed emergence. | | | | Author Profile | Full-Text PDF | |
