    一、莖色ノ發現ニハ互ニ補足的關係ヲ保有スル、二對因子之ニ關與ス。雜種體ハ、兩性的ヘテロナルカ單性的ヘテロナルカニ依リ、次世代ニ於テ紅色莖ト緑色莖トハ、夫々 9;7 或ハ 3:1 ニ生ズ。
    二、種子ノ色斑ニ關スルB•bトS•sトノ二對因子ハ、其ノ組合セニ依リテBSナレバ黒無地、bSハ赤無地、而シテbsハ赤姉子ヲ生ズ。然ルニBsハ黒姉子ヲ生ゼスシテ、斑姉子ヲ生ズ。コレ恐ラク因子ノ相互作用ニ依ルモノナランカ。
    三、高稿•福山兩氏ニ依レバC•cB•bトノ間ニ約0.6% ノクロツス•オーバーヲ算スルリンケーヂ關係ノ存スルモノノ如キモ (但シ兩氏ノ算出セル交叉率ハ約3%ナルモコレハ計算ノ誤) 其ノ證據確實ナラズ。余等ノ實驗ニ於テハ一株モクロツス•オーバーニ依リテ生ゼルモノヲ見ザリキ。之レヲ以テ兩對因子間ニ於ケルリンケーヂハ甚ダ強度ノモノナルベク、或ハ兩因子ハ同一ナルモノト思考スベキガ如シ。
    四、rsトノ間ニ於テモ、クロツス•オーバーヲ見ズ。故ニ前記cbトノ關係ニ於ケルト殆ド同樣ナル推論ヲ爲スコトヲ得ベシ。

    The above stated results of experiments may be summed up in following statements:
    1. The germination of air-dried seeds and of steeped seeds was accelerated by the irradiation of X-rays.
    2. The acceleration of germination is obviously shown in the seeds X-rayed in the air-dried condition, and the dose of 5H-10H seemed to be an optimum. 10H especially showed an evident acceleration of germination (refer to Germination Table 3).
    3. In the further growth after germination, pants grown from the seeds irradiated after 12 hours' steeping were worse than plants grownfrom the seeds X-rayed in the air-dried condition. In the latter case, between the state of growth of the controls and that of X-rayed material there appeared no great difference. But in the former case the irradiated showed the better growth in an earlier stage.
    4. In the case of steeped-irradiated material, 15H seedlings generally grew well. The 5H, 7H and 10H seedlings were poorer in growth than the controls at the time of germination, but in the further growth stages surpassed them.
    5. The acceleration of germination varies with the current (in the case of the same material and the same hour of exposure) and the hour of irradiation (in the case of the same material and under the same current) in a definite tube.
