图2 河农341和石家庄8号旗叶净光合速率A和叶绿素相对含量B的变化2011-2012 HN: 河农341; SJZ: 石家庄8号; HT: 高温处理; CK: 正常温度。高温处理为花后第8~22天, 处理后恢复常温生长, 取样日为花后第8、第12、第15、第18、第23和第26天。
Fig. 2 Changes of net photosynthetic rate A and relative chlorophyll content B in flag leaf of Henong 341 and Shijiazhuang 8 2011-2012 HN: Henong 341; SJZ: Shijiazhuang 8; HT: high temperature; CK: normal temperature. 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.
