摘要：The Effect of Ethyl Methane Sulphonate (EMS) on Growth and Variations of Marigold(Tagetes sp.)The aims of this research are to determine the variation of marigold (Tagetes sp) derived from seedtreated with EMS and to recommend the EMS concentrations that are able to induce varietion. Seedsof marigold cv Narai Orange were soaked in water for 6 hours, followed by soaking in EMS atconcentration of 0%, 0.3%, 0.6% and 0.9% for 4 hours. This study employed Randomized CompleteBlok Design with 10 replicates and each replicate consisted of 10 plants. Six plants were randomlychosen for measurements. The total number of samples observed were 240 plants. Observations weremade on the percentage of the growth, plant height, number of leaves, number of branches, diameterand weight of flowers. Data obtained from the observations were analyzed using Analysis of Variance(ANOVA), followed by DMRT (Duncan’s Multiple Range Test) if there is a significant differencebetween treatments. The EMS treatment reduced all characters observed. The EMS concentration of0.6% showed plant that had yellow flowers. The 0.9% EMS treatment resulted in one plant withchimera, 6 dwarf plants, 2 plants with thin stems, and 1 short plant with many branches. Untreatedplants did not show any variation.
