1. Studies of artificial male-sterility of egg plant induced dy chemical pouring were conducted. Chemical used was 2,4-D amin salt (contained 2,4-dichlorophenoxy acetic acid in rate of 41%) in concentration of 10 p. p. m. 2. That pollens of egg plants poured 2,4-D amin salt, almost lost viability in 3 days after, it was shown in pollen germination tests. 3. In microscopic observations, numerous empty pollens were found in ripen anthers poured chemical and it was found that developments and disintegrations of tapetum were same as those of normal anthers. 4. As disintegrations of empty pollen were progressive, normal pollen were surrounded by materials grown out of in this process, and were prevented to scatter through the opening of anthers by this manner (Fig 2 and 3). 5. Female remaind in fertile during this experiment, and normal sized fruits contained seeds were havested. But narrow leaves, inhibiting of growth, creeping of branches and increasing of number of branches were observed in poured plants. 6. In this experiment, it was revealed that the artificial male-sterility was possible by chemical treatments.
