Response of geranium (Pelargonium graveolenus L.) to gamma irradiation and foliar application of speed grow

摘要

Field experiments were carried out during two successive seasons to investigate the effect of gamma rays (0, 2 and 4 K-tad) and/or foliar application of Speed Grow fertilizer (0, 1000 and 2000 ppm) on growth and volatile oil composition of geranium (Pelargonium graveolenus L.). The maximum values of growth characters and volatile oil yield were obtained as a result of the interaction treatment between irradiation at 2 K-tad and foliar spray of Speed Grow at 1000 ppm. Citronellol which is the main component of geranium volatile oil was reached its maximum value as a result of gamma rays at 2 K-rad in combination wih foliar spray at 2000 ppm.
