  1. aAfter seed soaking, the seeds (50 seeds/replicate, n = 3) were drained and sown in trays containing pot mixture and then placed in a glass house and maintained at 28°C.
  2. bValue expressed in nmol C2H4 day-1 seedlings-1. Each value represents mean ± standard deviation (SD) of three replicates per treatment.
  3. cSeedling vigour index[36] was calculated using the formula: SVI = % germination × seedling length (shoot length + root length) in cm.
  4. dRate of germination (RG) was calculated using the following formula, RG = ∑ Ni/Di where Ni is the number of germinated seeds in a given time, and Di is the time unit (day).
  5. eEach value represents mean of three replicates and expressed in grams. Samples were measured at 45 DAS.
