Effects of various treatments to the stigma to overcome varietal crossing incompatibility in chrysanthemum were investigated. Stigmas were treated with distilled water (control), ethanol, organic solvents (hexane, ethylacetate), vitamins (folic acid, nicotinic acid), amino acids (alanine, arginine, glycine), and plant growth regulators (indole-3-acetic acid (IAA), naphthaleneacetic acid, benzyladenine) at the concentrations of 200 and 400 ㎎ㆍL?¹, IAA and nicotinic acid produced more seed set than control. All amino acids used in this experiment contributed to increasing seed set. Some cultivars showed increased seed set with the crossing of two pollens (‘SeiAlps’ and ‘Yeonja’), whereas the others showed only increment with ‘SeiAlps’. According to the microscopical observations, low callosic deposit, no secretion on the stigma, and collapsed papillae were observed in compatible crosses, and also effective solution treatments. The solution treatments of amino acids, IAA, and nicotinic acid to stigmas can be recommended to be more effective than the other solutions to overcome the inhibition of incompatibility in varietal crossing of chrysanthemums. The method is practical and easy to treat on plants with no other equipments, and the effects on the increasing of seed set were also satisfactory.
