In the present study, drought tolerance potential of chickpea and lentil seeds under different boron levels were assessed. One chickpea (Azkan) and one lentil cultivar (Sahan) were selected for the genetic material. To provide drought condition, different level of polyethylene glycol solution (PEG 6000) was applied to seeds. Germination experiments were performed under PEG-induced stress to

Effects of these abiotic stresses were determined with the measurement parameters of germination rate and root traits. Drought stress adversely affected to germination rate and seedling growth characteristics in chickpea and lentil. Especially, seed germination rate extremely reduced by increased level of drought stress. An increase in PEG levels from 0 to -4 MPa drastically decreased root and shoot width, shoot length in chickpea whereas they did not generate a significant difference in seedling growth traits except for root width in lentil. Additionally, the results showed that increasing boron treatments decreased germination rate in both chickpea and lentil. The low concentration of boron (5 mM) increased root and shoot length; however, a remarkable decrease was observed in root and shoot growth traits at the highest concentration of boron (10 mM). The overall findings show that germination and seedling growth parameters were greatly inhibited by different concentrations of PEG and > 10 mM boron levels for chickpea and lentil production.
