Abstract: Yield and viability of seeds taken from Dalapontreated pepper plants were investigated in this report. Miemidori, a cultivar of sweet pepper was used. The plants were sprayed with 30 milliliters of aqueous solution per plant containing 200, 400, 600, 800, 1, 000, 1, 200 and 1, 400 milligrams of Dalapon per liter. Very little influence on fruit setting was observed while seed setting was strongly affected by the treatment, and the number of seeds per cross decreased with the use of high concentrations. After 1, 000 or 1, 200ppm applications the number of seeds per cross was approximately one third in comparison with non-treated. The decrease of seed number seems to result from both the decreased number of ovules and other physiological disorders. Seeds produced after the use of higher concentrations were larger than those of control or lower concentrations. On the other hand, the germination rate of harvested seeds decreased with the use of high concentrations.
