Fig. 2From: iTRAQ-based quantitative proteomic and physiological analysis of the response to N deficiency and the compensation effect in riceAnalysis of net photosynthetic rate, Fv/Fm, SPAD value and GPT activity. (a) Net photosynthetic rate, (b) Fv/Fm, (c) SPAD value, (d) GPT activity. The column data in figure is average, and the short lines represent the mean square deviation. Values in the same column show means via Tukey’s multiple range test. Different lowercase letters represent significant differences (p < 0.05). NST: normal N supply at the tillering stage, NDT: N deficiency at the tillering stage, NSP: normal N supply at the young panicle differentiation stage, NCP: N compensation at the young panicle differentiation stageBack to article page
