-Seeds were germinated on wet filter paper at room temperature in the dark under sterile conditions for three days before transfer to sterile jars containing solid 1/10 plant nutrition medium (PNM), pH 5.7 and 0.4% Gelrite (Duchefa, Haarlem, the Netherlands). Seedlings were cultured for six days in a growth chamber under long-day conditions (day/night cycle of 16/8 h, 22 C/18 C, light intensity of 108 mmol$m2$s1). Root and shoot fresh weight as well as length of the barley plants were measured.
