Abstract
The effect of different concentrations of indole butyric acid (IBA) at 4g/L and 0.12/31.2 ml hardwood and semi hardwood cuttings of coratina olive was observed. Cuttings were taken in the month of February from coratina plant and dipped for 10 seconds in the required IBA solutions. The highest survival percentage, shoot formation, number of roots formation was maximum in 4g/L treated hardwood cuttings. The maximum number of branches were observed in hardwood cuttings as compared to softwood cuttings. It was concluded that either type of olive cutting treated with IBA solution 4g/L showed best results to propagate coratina olive.
Highlights
The olive tree olea europea is valuable for its beauty and fruit. olea europea is locally known as zaitoon, it belongs to a family of oleaceae
The minimum number of plant survived was observed in indole butyric acid (IBA) treatment 0.12/ 31.2 ml. these results are with the findings of siddique and hussain 2007[6], the plant survival with hight IBA concentration can link directly to the growth regulators capacity
The maximum roots were shown by treatments with high IBA concentration and minimum were observed in the least Treated IBA concentration
Summary
The olive tree olea europea is valuable for its beauty and fruit. olea europea is locally known as zaitoon, it belongs to a family of oleaceae. The lateral rooting in olive is induced by IBA. The present study is planned to evaluate the performance of different types of olive cuttings treated with different concentrations of Indole Butyric Acid (IBA) [1]. In commercial olive propagation IAA is not used as rooting promoter. IBA is non-toxic to the hardwood and semi hardwood cuttings.
