Evaluation the effect of rooting media and hormonal concentrations (IBA) in three olive cultivars growing in SiwaOesis-Egypt

並列摘要


This study was carried out to determine the effects of three rooting media (perlite, mixturepeatmoss+perlite and Sand+peat-moss) and Indole Butyric Acid (IBA) treatment (2000, 4000 or 5000 ppm) on rooting ability of three olive cultivars from Siwa Oasis, Egypt (Hamed, Wateken and Maraki). Parameters were measured, the percentage of cuttings that rooted, the number of roots produced by cutting and the survival rate.These parameters were significantly influenced by the interactive effect of rooting media, cultivar and IBA treatment. The cuttings planted in perlite had higher rooting percentage than those planted in perlite&pet-moss and sand&pet-moss with a significant differencebetween cultivars. Very low rooting accurred in cuttings dipped in low concentration for all cultivar and rooting media.The greatest percentage of rooting (100 %), were in 4000 and 5000 ppm IBA in perlite medium with Wateken and Hamed variety, respectively, the highest percentage of rooted cuttings was observed in perlite (100%), perlite&pet-moss 1:1 (80%) and sand&pet-moss 1:1(70%) with cultivar Hamed and Wateken respectively, while Maraki cv. Recorded worst performance in all substrates tested. The results showed that cultivar had a significant effect on all measured parameters.
