Barley seed sensitivity to water stress at germination stage.
Original language description
Standard germination, mean time of germination (MTG), germination in sand wetted by water to 100 % water capacity (anoxia) or by hydrogen peroxide (wet conditions without anoxia), germination in 0,75 % hydrogen peroxide and laboratory emergence (15 oC and 20 oC) were evaluated. Barley seed responds sensitively to stress conditions during germination. Significant germination decrease was found in abundance of water. Percentage of reduction depends on the variety and on the year of seed production. Extreme values of water sensitivity are in interval 4 - 90 %. At wetted sand by 0,75 % solution of H2O2 the germination was significantly less reduced. That means, barley seed is very sensitive to oxygen deficiency above all and is less injured by quick imbibition. Quick test of germination in 0,75 % hydrogen peroxide deserves attention for its high correlation coefficient with the seed laboratory emergence. The results significantly demonstrate a higher sensitivity of deteriorated seed to ger
