Research is being conducted on computer-assisted technology in greenhouse cultivation, in particular the development of methodologies for automatic environmental control and new equipment for environmental control, with the aim of systemizing efficient technology that will decrease the amount of labor required.

If we can use this flowering hormone to make plants flower freely, we can diversify vegetable production and breeding. For example, by harvesting fruit and seeds from plants that normally have difficulty in flowering, or by reducing the time needed for breeding by allowing flowering in any season, a wider range of vegetable production will become possible. We are working on developing the technology to efficiently deliver flowering hormones and induce flowering rapidly, using a technique called grafting.<\/span><br \/>\n<span style=\"font-size: 10pt\">\u3000Currently, we are mainly targeting cruciferous vegetables such as cabbage, broccoli, and radish. We are tackling issues such as the development of &#8216;flowering-inducing rootstocks&#8217; that can supply large amounts of flowering hormones through genome breeding. As well as the development of environmental control methods that promote the synthesis of flowering hormones. Finally we are analyzing the reasons for graft incompatibility between radish and cabbages.<\/span><\/p>\n<table style=\"border-collapse: collapse;width: 100%\">\n<tbody>\n<tr>\n<td style=\"width: 50%\"><a href=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas09_plant\/img3.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas09_plant\/img3.png\" alt=\"null\" width=\"831\" height=\"1203\"><\/a><br \/>\n<span style=\"font-size: 10pt\">Research on rapid flowering induction of cabbage by grafting onto radish rootstocks<\/span><\/td>\n<td style=\"width: 50%\"><a href=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas09_plant\/img4.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas09_plant\/img4.png\" alt=\"null\" width=\"1082\" height=\"577\"><\/a><br \/>\n<span style=\"font-size: 10pt\">Field cultivation experiment of cabbage<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><span style=\"font-size: 10pt\"><strong>Publications<\/strong><\/span><\/p>\n<p><span style=\"font-size: 10pt\">\u30fb\u5b89\u898b\u660e\u9999\u91cc, \u4e2d\u5ddd\u307b\u306e\u304b, \u5409\u7530\u88d5\u4e00, \u5f8c\u85e4\u4e39\u5341\u90ce, \u5317\u6751\u5609\u90a6, \u5b89\u5834\u5065\u4e00\u90ce: \u30ad\u30e5\u30a6\u30ea\u690d\u7269\u4f53\u91cd\u91cf\u306e\u65e5\u5909\u52d5\u304b\u3089\u898b\u305f\u65e5\u5c04\u304a\u3088\u3073\u679c\u5b9f\u306e\u6709\u7121\u306b\u3088\u308b\u5438\u6c34\u7279\u6027. \u5712\u82b8\u5b66\u7814\u7a76\uff08\u5370\u5237\u4e2d\uff09.<\/span><br \/>\n<span style=\"font-size: 10pt\">\u30fbMotoki K., Kinoshita Y., Nakano R., Hosokawa M. and Nakazaki T.: Investigation of the field performance of progenies obtained by a non-vernalization-grafting floral induction method in terms of application to cabbage breeding and seed production.
