FLOWERING IN FREESIA: TEMPERATURE AND CORMS
Year round cultivation of Freesia in glasshouses is rather complicated. Therefore a considerable amount of research was done in The Netherlands, where Freesia production is of economic importance. However, most of the data are only available as internal reports of the Glasshouse Crops Research Station at Naaldwijk, and they are in Dutch. Messrs. van de Nes and Dijkhuizen performed these experiments and produced the reports (see 1). This article has the aim to summarize very briefly all practically important data. Apart from the very early work by Hartsema and Luyten (2, 3, 4, 5) recently a study has been published by Mansour about his work in the phytotron of the Laboratory for Horticultural Crop Growing at Wageningen (7). Some of his tables are very nice summaries of work at Naaldwijk and they add new observations as well. Some of the data of this thesis are gratefully incorporated in this article.
