Abstract

SummaryStrawberry plants were allowed to initiate flower buds out-of-doors, then transferred to artificially illuminated cabinets for forcing. The yield of fruit was found to be independent of the nutritional treatments given (balanced, low nitrogen, high potash) but was highly dependent on the lighting regime, long days giving more fruit than short days or short days plus a night break.All the light given was from white fluorescent tubes and the night break treatment did not promote the long-day effects that might have been expected, possibly because there was insufficient far-red radiation for phytochrome synthesis.
