- Note on Spore Germination and Protonemal Growth Controlled by Day Length in Bryum pseudo-triquetrum
Abstract
The spore germination and the further protonemal growth of Bryum pseudotriquetrum took place under more than nearly 12hours of light in 24hour cycles. When a short period of light such as 2 minutes or more was inserted in the middle of the 16hours dark period where no germination and growth occurred, the inhibitory effect of the dark period was completely removed. Fig. 3. Effect of light-break on the spore germination and the protonemal<br>growth under the cycle consisting of 16hours dark and 8hours light periods. The filled circles indicate protonemal growth and the open ones spore germination. The open circle (1) and (2) show the results of different experiments. c on the abscissa means continuous illumination. The authors are greatly indebted to Prof. S. Imamura and Assist. Prof. M. Hamada of Kyoto University for their valuable criticism, and to Assist. Prof. T. Yabuno of<br>the University of Osaka Pref. who gave every available facility for the present work. The authors also wish to express their thanks to Dr. Z. Iwatsuki of the Hattori Botanical Laboratory for his kind advice in the identification of the species.
