图1. 不同空气温度/根区温度处理对巨峰葡萄叶片F_v/F_m (A)、Y(II) (B)、Y(NPQ) (C)和Y(NO) (D)的影响
不同小写字母表示差异显著(P<0.05)。F_v/F_m: PSII最大光化学效率; Y(II): PSII实际光化学量子产量; Y(NPQ): 调节性能量耗散的量子产量; Y(NO): 非调节性能量耗散的量子产量; PAR: 光合有效辐射; CK: 对照; T1: 高气温; T2: 高根区温度; T3: 高气温和高根区温度交叉作用

Figure 1. The influence of different air temperature/root zone temperature treatments on the F_v/F_m (A), Y(II) (B), Y(NPQ) (C) and Y(NO) (D) of Kyoho grape leaves
Different lowercase letters indicate significant differences (P<0.05). F_v/F_m: PSII maximum photochemical efficiency; Y(II): PSII actual photochemical quantum yield; Y(NPQ): Regulated energy dissipation quantum yield; Y(NO): Non-regulated energy dissipation quantum yield; PAR: Photosynthetically active radiation; CK: Control; T1: High air temperature; T2: High root zone temperature; T3: Cross processing of high air temperature and high root zone temperature
