Treatment with high concentrations of GA3 is effective in overcoming dormancy and causing rapid germination of
seed. The germination substratum may be moistened with 500 ppm solution of GA3 and infact when the dormancy is
weaker, 200 ppm may be enough, while when it is stronger upto 1000 ppm solution may be used. (Agrawal 1994 [17]).
Several workers have reported that many types of seed dormancies are overcome by dry storage for varying period of
time (Krishna, A. and Tyagi, 1976 [18], Mukherjie, S.M., 1966 [19]). GA comprise of the class of hormones that are
most directly implicated in the control and promotion of seed germination (Hsigo and Vidaver, 1984 [20]; Singh, 1979
[21]; Sharma and Chakraborty, 1976 [22]). Applied Gibberellins can function in relieving many types of dormancy.
GA3 increase germination percentage of Anemone coronaria seeds at supra optimum (25°C) but not at optimum
temperature 10°-20°C temperature.
