Pepper fruits were harvested at 5-days intervals until the 60th day after anthesis, and germination powers of seeds at each stage were investigated. Germination power of pepper seeds came into first appearance at the 30th or 35th day, when the quantitative fruit growth almost entirely ceased, and it increased with fruit maturity until the 50-day-old stage. Storing of the harvested fruits for 60days at room temperature caused remarkable increase in both germination per cent and germination energy. Effect of after-ripening was higher for the Japanese varieties than for the foreign (Harris' Early Giant). The time most favorable to the harvest of pepper fruits for saving seeds appears to be between the 50-and 60-day-old stages after anthesis, but it will be also recommendable for pepper seed growers to harvest fruits at the 30-or 35-day-old stage and bring about higher germination percentage of seeds by subsequent storage of the fruits at room temperature.
