Effect of Rooting Media and Planting Time on Rooting of Manzanillo and Coratina Olive (Olea europaea L.)Cultivars under Shaded Polyethylene Tunnel

摘要

THIS INVESTIGATION was conducted through 2006 and 2007 seasons in the Research Farm of the Horticulture Research Institute at Giza. Two olive cultivars (Manzanillo and Coratina) were used as plant materials to study the effect of planting date and media on rooting percentage, root length, number of roots/cutting and root weight. The cuttings were planted under shaded tunnel inside a net-house. Data showed that, cuttings of Manzanillo gave the highest rooting and survival percentage compared to Coratina cultivar. January and April were the proper time for cutting preparation. As for the planting media, sand: peat moss (2:1 v/v) resulted in good rooting characters and survival percentage after 1 and 2 months from transplanting in both seasons.
