This study was conducted during two successive seasons 2014 and 2015 at the nursery of Pomology department, Faculty of Agriculture, Cairo University, Egypt. It is aimed to investigate the influence of wounding, sucrose (1%) and antioxidant (mixture of 5% citric acid + 5% ascorbic acid) either alone or in combination with 0, 3000 and 5000 ppm IBA on rooting of guava softwood cuttings. Results showed that IBA at 3000 ppm was more efficient compared with the IBA at 5000 in promoting rooting, root length, weight and number. Wounding and antioxidant improved rooting and root parameters. The application of IBA at 3000 either alone or accompanied with antioxidant significantly increased rooting percent, root length, and number. Results indicated that IBA increased root weight through increasing root number rather than root length of guava cuttings.
