Abstract

In order to study the effect of different levels of drought stress and temperature on seed germination of buckwheat, a factorial experiment was conducted as completely randomized design with three replications. Experimental treatments were included different levels of drought stress (0, -0.2, -0.4, -0.6 and -0.8 MPa) and different temperatures (8, 12, 16, 20, 25, 30, 35 and 40 oC). Results indicated that all models of thermal time, hydro time, and hydrothermal time could predict the germination of buckwheat in temperature and osmotic potential. Basic temperature (Tb) was estimated from -0.98 to 11 oC, optimum temperature (To) from 21.7 to 24.7 oC, and maximum temperature (Tc) from 30 to 41.5 oC, which osmotic potential increased Tb and decrease To and Tc in Buckwheat. Also, increasing temperature enhanced germination rate (decrease θHT from 18 MPa day at 8 oC to 3 MPa day at 35 oC), and decreased stress tolerance due to increasing basic potential (increase ψ50 from -0.927 MPa to 0.043 MPa). According to the hydrothermal time model output, Tb in this plant was about 1.93 oC and at 92 MPa oC day, highest germination rate was recorded and ψTb in this plant in Tb was about -1.31 MPa. Also it was defined that, each of these three models predicted buckwheat seed germination under different temperature and water potential, but hydrothermal time was a general model and we can suggested it.
