The effect varied between species. Exposure to EOD-FR light for 15 minutes promoted stem elongation in Chrysanthemum morifolium Ramat. 'Dekmona', 'Sei-elza', and 'Tourmalin', but it had no effect on stem elongation in C. morifolium 'Jimba'. Exposure to EOD-FR light for 30 minutes promoted extension growth in Helianthus annuus L. 'Sunrich Orange' and 'Summer Sunrich Pine 45', Antirrhinum majus L. 'Calyon White' and 'Reisen', Matthiola incana (L.) R. Br. 'Pink Iron', Bupleurum spp. 'Green Gold', and Dianthus caryophyllus L. 'Barbara' . Exposure to EOD-FR light for 30 minutes also promoted flowering in two cultivars each of H. annuus and A. majus and in M. incana, Bupleurum spp., and D. caryophyllus. However, exposure to EOD-FR light had no effect on extension growth or flowering in Gerbera jamesonii Bol. ex Adlam 'Orlando', Zantedeschia spp. 'Crystal Blush', Cosmos bipinnatus cv. 'Miyoshi-no-versailles', and Rosa Hybrid Tea Group 'Bonheur'. Furthermore, exposure to EOD-FR light for 30 minutes promoted stem elongation but delayed flowering in Celosia argentea L. var. cristata (L.) Kuntze 'Delhi Pearl'. Exposure to EOD-FR light for 30 minutes had no effect on stem elongation or delayed flowering in Callistephus chinensis (L.) Nees 'Selene Pink'. The effect of EOD-FR light on flowering and extension growth showed seasonal variation in C. morifolium 'Dekmona' and 'Sei-elza', 2 cultivars of H. annuus, and C. argentea. These results suggest that EOD-FR light can be applied to the cultivation of plants under greenhouse conditions, although the method of EOD-FR lighting must be optimized for each species.}, pages = {1--11}, title = {数種切り花類の開花および茎伸長に及ぼす明期終了時の短時間遠赤色光照射(EOD-FR)の影響}, volume = {9}, year = {2009}, yomi = {スミトモ, カツヒコ and ヤマガタ, アツコ and シマ, コウジ and キシモト, マサユキ and ヒサマツ, タモツ} }
