Abstract

 In this paper, the effects of petroleum ether, chloroform and ethyl alcohol extracts of Pistacia terebinthus leaves at 100 and 200 ppm doses and Giberellic Acid (GA3), which is used commonly as plant-growth hormone were investigated on plant height, inflorescence survivor and numbers of Pelargonium ‘Ringo Deep Scarlet’. The applications of GA3 and all extracts lengthened the inflorescence survivor of pelargonium in comparison to untreated control group. However, two doses of GA3 significantly reduced the inflorescence numbers of pelargonium. Contrarily, 200 ppm doses of ethanol and petroleum ether extracts increased the inflorescence numbers. As expected, all doses of GA3 significantly increased the plant height as compared with control group (p<0.01). However, all treated doses of ethanol extract of P. terebinthus showed the weak inhibitory effect on the plant height of pelargonium.
