The Effect of Deep SeaWater on Seed Priming of Sweet Pepper (Capsicum annum L.), Rice (Oryza sativa L.) and Ginseng (Panax ginseng C.A.Meyer)

초록

This experiment was conducted to study whether primingwith deep sea water results in enhancement of seed germi-nation and to identify the optimum concentration of the priming solution, and duration of priming using sweet pepper (Cv.pper and rice seeds were primed with 5 various concentrations(5%, 10%, 15%, 20% and 30%) for deep sea water for 48 hours, 24 hours and 12 hours at 25 and ginseng seeds in 5%, 10%,℃15%, 20%, 25%and30%, and2,4,6, and8electricalconductivity(EC) whichweremadebydesalinatingdeepseawater. Primingin deep sea water (DSW) improved the early and final germination percentage, mean germination rate, emergence percentageand root andshoot length, compared withplain water, KNO3andwithout primingtreatments. Insweet pepper, 24hours primingwith 5 percentage DSW significantly improved the early germinamean germination and emergence days andearly emergence percentage, comparedwith KNO3and control. Whereas, in rice, 48hours priming with 10 percent DSW significantly improved theearly germination percentage, plumule emergence percentage,root length and shoot height. Hence the best seed priming treatment on sweet pepper and Rice are 24 hours with 5 percentageDSW and 48 hours with 10 percentage DSW, respectively, whereas in ginseng, priming with EC4, EC8 and 25% DSW hadshown better germination.Key words- Germination, Rot, Emergence, Radicle, Imbibition
