efficiency (i.e., the number of marketable stems produced per unit of energy input) is low. Lowering the temperature set point in the greenhouse could be a way to increase this energy efficiency. This may, however, have adverse effects on crop growth and
. Several factors influence the growth and development of plants, and the primary determinant of plant development is temperature ( Lopez and Runkle, 2004 ; Moccaldi and Runkle, 2007 ). Temperature is commonly manipulated by producers and is dependent on
water and analyzed using high-performance liquid chromatography [HPLC (model L-6200; Hitachi, Tokyo, Japan)] with a polymer-based column [4.6 mm i.d. × 25 cm (Shodex ODP2 HP-4E; Showa Denko, Tokyo, Japan)]. The column temperature was set at 30 °C and the
Apple trees suffer from lethal and sublethal injury when severely cold temperatures occur following a warm spell or after trees have deacclimated ( Howell and Weiser, 1970 ; McArtney and Obermiller, 2011 ). In some apple cultivars, tree trunks
