Assesment of seed germination and seedling growth of catharanthus roseus under salinity stress and priming

An experiment was conducted based on a factorial in a completely randomized design with three replications. The factors include four salinity levels using sodium chloride and five priming levels. The results showed seed priming was effective in modulating the effect of stress at all salinity levels. Potassium nitrate priming was more effective than ascorbic acid. In treatment without salt stress, the application of priming in some levels, increased seedling length and seedling vigor index compared to the control.
