Plants were grown on each ridge (10.9 m in length and 70 cm in width), and the measurements were performed in the plot surrounded by white lines at the east-side ridge. A 13.5 cm gridlike flower net with five rows was set on the canopy. Two plants were grown per grid, except in the middle row, where the duct for zone cooling was located.

... Research Centre (33°32ʹ84ʺN, 130°71ʹ22ʺE) on the 6th and 7th of August and also on the 25th of September, 2020. Four ridges (each 10.9 m long and 70 cm wide) were created in the greenhouse with loamy soil, and summer-to-autumn flowering cultivars of Chrysanthemum × morifolium Ramat., namely 'Sei no issei' were planted on the 25th of June, 2020 (Fig. 1). The plants were irrigated twice a day, early in the morning and in the evening, and N: P 2 O 5 : K 2 O (13: 14: 8) fertilizer was applied at a rate of 2 g per plant. The plants were subjected to night-break (22:00-3:00) treatment with red-emitting LED lamps (FR-MP; D-market Inc., Osaka, Japan) from the 19th of July (24 DAP: days after ...

... top cooling treatment, the region at a height of more than 70 cm was cooled remarkably well, ranging from 22 to 25°C, when R s was between 150 and 250 W m -2 in an elapsed time of 5-13 min (Fig. 10). Other than during these cooling periods, T can in the analysed region even in the cooling targeted location exceeded the optimum temperature for chrysanthemum growth and T can rose further after cooling was discontinued, which may be the cause of a flowering delay by suppressing reproductive growth (Nozaki and Fukai, 2008). ...
