Abstract

Seed priming is a technology that positively influence seedling establishment in many crops and may improve field performance under adverse environmental conditions. Therefore, in this research the effect of seed priming durations (0 (P0), 8 (P1) and 16 (P2) hours) on some morphological characteristics of safflower under different irrigation treatments (Irrigation after 60 (I1), 90 (I2), 120 (I3) and 150 (I4) mm evaporation from class A pan) was investigated. Results showed water stress decreased mean of plant height, stem diameter, leaves per plant, branches per plant, capitol per plant and capitol diameter. Hydro-priming increased all of these traits. The highest mean for these traits was recorded for hydro-priming at 16 hours duration period. It was, suggested that this priming duration is the best treatment for invigoration of safflower seeds.

Keywords

capitol, hydro-priming, plant height, safflower, stemdiameter.

Conclusion

Hydro-priming, especially for 16 hours duration period increased the plant height, stem diameter, leaves per plant, branches per plant, capitol per plant and capitol diameter. That lead to ability of safflower to grow successfully in the field. Therefore, hydro-priming is a simple, low cost and environmentally friendly technique for improving safflower morphological characteristics.
