Fig. 3 Changes of MDA and Pro contents in different organs of Henong 341 and Shijiazhuang 8 under high and normal temperatures 2011-2012 HN: Henong 341; SJZ: Shijiazhuang 8; HT: high temperature; CK: normal temperature. A1, B1: flag leaf; A2, B2: sheath; A3, B3: peduncle; A4, B4: glume; A5, B5: grain. Wheat plants recovered normal growth temperature after the high temperature treatment from the 8th to the 22nd day after anthesis, and the sampling days were the 8th, 12th, 15th, 18th, 23rd, and 26th day after anthesis.
