Item In vitro micropropagation of olive (Olea europaea L.) ‘Mission’ by nodal segments(Uludağ Üniversitesi, 2012) Rostami, Ahmad Ali; Shahsavar, AliOlive (Olea europaea L.) cultivars are mainly propagated by hardwood cuttings under mist unit of greenhouses. Such techniques are time consuming, laborious and have limited efficiency. In vitro propagation methods may be a good alternative for propagation of olive cultivars. Current study was conducted to establish a successful and high efficient method for micropropagation of olive ‘Mission’ via nodal segments. Results of this study showed that production of phenolic compounds and necrosis of explants may be controlled by submersing the explants in a mixture of 100 mg L-1 citric acid and ascorbic acid for 30 minutes, after submersion in water for 2 hours. The best proliferation rate and growth obtained in the presence of benzyladenine and gibberellic acid at the rate of 2.1, 2.08, and 0.6 mg L-1, respectively. Proliferated explants rooted on MS/2 supplemented with 4 mg L-1 indolbutyric acid. Rooted explants adapted to outdoor condition by placing them under ordinary mist/cooling unit system of a greenhouse. The method described in this study is suitable for bulk propagation of olive ‘Mission’ in a period of three to four months; however the applicability of the method should be evaluated for other olive cultivars.Item The influence of urea, boric acid and zinc sulphate on vegetative traits of olive(Uludağ Üniversitesi, 2012) Amin, Pegah Sayyad; Shahsavar, AliIn calcorous soils of Iran, dissolving of nutrient elements especially micronutrients were slow. The objective of this project was to estimate the effect of foliar application of boric acid, zinc sulphate (0, 2000 and 4000 mgL-1) and urea (0, 5000 and 7500 mgL-1) on vegetative traits of olive. Results showed that in first year, the most fresh and dry leaf weight were seen in 2000 boric acid plus urea at 5000 mgL-1. The most leaf area and chlorophyll were observed in boric acid and zinc sulphate at 4000 mgL-1 alone and boric acid at 2000 plus urea at 7500 mgL-1, respectively. In second year, the highest shoot length was seen in zinc sulphate at 4000+boric acid at 2000 plus urea at 5000 mgL-1. The highest no of nodes and leaf area was observed in zinc sulphate at 2000 with boric acid at 4000 mgL-1.
