The Chemical Composition of Membrane Lipids in Acclimation to Chilling of Squash (Cucurbita moschata Duch. cv Shirogikuza) Seedlings The Chemical Composition of Membrane Lipids in Acclimation to Chilling of Squash (Cucurbita moschata Duch. cv Shirogikuza) Seedlings 今井, 博之 619 イマイ, ヒロユキ 40278792 IMAI, Hiroyuki Ohnishi, Masao 229 Ito, Seisuke 230 Ohnishi, Masao 232 Ito, Seisuke 233 ceramide monohexoside chilling acclimation Cucurbita phosphatidylcholine phosphatidylglycerol ceramide monohexoside chilling acclimation Cucurbita phosphatidylcholine phosphatidylglycerol 110000039561 application/pdf Chilling-tolerance of squash (Cucurbita moschata Duch. cv Shirogikuza) cotyledons was measured after 3 d of cold acclimation at 12℃. Squash seedlings grown at 12℃ (chilling-treated, CT) and 25 ℃ (non-treated, NT) were analyzed to examine whether the chilling treatment affected lipid composition and content. A slight decrease of sterol lipid/glycerophospholipid ratio was observed in CT seedlings, and although the levels of unsaturated fatty acids in phosphatidylglycerol were not significantly different between the two seedlings, the level of 3-E-hexadecenoic acid increased slightly in CT seedlings. In phosphatidylcholine, the level of linolenic acid slightly increased in the CT seedlings. In ceramide monohexoside, the levels of 8-Z- and 8-E-stereoisomerism of 4-hydroxy sphingoid bases were essentially the same between the two seedlings, while a slightly increased level of 2-hydroxy palmitic acid was observed in CT seedlings. The involvement of lipids in the change to chilling sensitivity is discussed in this experiment. departmental bulletin paper 甲南大学 2003-07-31 VoR application/pdf 甲南大学紀要. 理工学編 1 50 27 39 Memoirs of Konan University.
