The corms of Spotlight and Snow Princess were used as the materials. These experiment were carried out at Kyoto University in 1964. Corms were divided into four lots according to their weight (Table 1), and they were planted in pot with sand on May 20. Half in each lot was set up under the darkness, and the other half under the light (600 lux or less) condition in a glasshouse of the Phytotron regulated at 20℃. The results obtained are summarized as follows; 1. There was no remarkable difference in plant height between the lots more than 10g, but it is evident that in the dark condition the plant height was more higher than in the light. 2. When four lots of corm weight were set up as 4-5g, 9-log, 20-24g and 34-46g, the number of leaves formed were about 2, 3, 4 and 4-5 respectively. 3. Flower bud differentiation was observed in plants formed more than 4 leaves. 4. Growth interruption of the growing point or flower bud was hastened not only with decreasing of mother corm weight, but also in the dark condition comparing with in the light. 5. Development of new corm was hastened not only with decreasing of mother corm weight, but also in the dark condition comparing with in the light. From these results, it may be considered that the flower bud differentiation with storage nutriment in mother corm will be induced in more than 20g of corm weight, and that growth interruption periods of the growing poit or flower bud are almost in accordance with the beginning of conspicuous growth of new corm, and those periods will be subjected by either internal or external condition such as nutriment of mother corm or light., Article, 信州大学農学部紀要 4(3): 207-214(1967)}, pages = {207--214}, title = {長野県におけるグラジオラス栽培の基礎的研究 第5報 グラジオラスの生育におよぼす母球の影響}, volume = {4}, year = {1967} }
