Table 3 One-way ANOVA results of effects of different treatments (HP: Hydro-priming, NiNP_20: NiO-NPs at 20 mg/L, NiNP_40: NiO-NPs at 40 mg/L, NiNO3_20: NiNO3 at 20 mg/L and NiNO3_40: NiNO3 at 40 mg/L) on photosynthetic parameters (urease enzyme, ammonia, nitrate, chlorophyll a, chlorophyll b, total chlorophyll, chlorophyll a/b ratio) and RWC (relative water content), of BARS (Bars-09) and SSB (Sarsabz) cultivars of wheat. Values are represented as mean ± SD (n = 3).

n.s

  1. Lower case letters represent significance level at p < 0.05 according to Fisher’s least square difference (LSD) test. Treatments with similar lower case letters are not significantly different.
  2. n.s. = Not significant; * = p < 0.05; ** = p < 0.01; *** = p < 0.001.
  3. T* = P-value among treatments; CV* = P-value among cultivars.
