Abstract
In the author's previous papers, it was reported that the tube of Petunia pollen, which was pollinated upon the stigma of the egg plant, penetrated deeply into the style and stimulated the ovary to grow into a seedless fruit, and also that the tomato pollen, smeared, did not stimulate the ovary of the egg plant.In this paper, some additional data obtained from further studies will be presented.(I) It was found that the ovaries of egg plants had already began their parthenocarpic growth when the pollen tubes of Petunia violacea reached the ovaries.(2) When the water extract of Petunia pollen was injected into the ovary of the egg plant, that ovary developed often into a parthenocarpic fruit.(3) The microscopic observations of the cells in the ovarian tissue near the injected part indicated that the cell division was stimulated.(4) It was not certain, however, whether this stimulation of the cell division was due to the presence of the extract of the Petunia pollen, or the wound hormone that might have been produced in the wounded ovarian tissue.(5) So, a pure water injection was tried, but no ovary was found to be stimulated in their parthenocarpic growth.(6) Next, ovaries were either injected with the water extract of tomato pollen, or pricked by a needle. In either case the ovaries were rarely stimulated to develop into parthenocarpic fruits.(7) But, the degree of the growth, in these cases, was by far inferior to that in the case, in which the extract of the Petunia pollen was injected.(8) These results suggest that the tube of the Petunia pollen may give some chemical stimulation to the ovary of the egg plant by its deep penetration into the style.(9) It may be additionally mentioned here that the results of the author's experiments with Nicotiana sp. are in accord with the results above stated.
