Vegetative propagation of pear rootstocks using semi hardwood cuttings The objective of this work was to evaluate the technical viability of the vegetative propagation of the pear rootstocks ‘Taiwan Nashi-C’, ‘Taiwan Mamenashi’ (Pyrus calleryana Dcne.) and ‘Seleção IAC-1’ (Pyrus spp.) using semi-hardwood cuttings. The experiment was conducted in a nursery with an intermittent mist system at the...

Shoot tip cuttings of Quercus phillyraeoides A. Gray ‘Emerald Sentinel’ (‘Emerald Sentinel’ oak), in a transitional growth stage between softwood and semi-hardwood, were collected from containerized plants growing under uniform fertility on June 4, 1998. Cuttings were treated with talc formulations of indolebutyric acid (IBA), ranging from 0 to 8000 ppm (0.8%), and placed under intermittent mis...

starting from semihardwood branches of peach and plum rootstocks (Prunus cerasifera E.) cv. mrs2/5, plum rootstocks (Prunus cerasifera × P. salicina) × (P. cerasifera × P. persica) cv. ishtarà and olive tree (Olea europaea L.) cv. Frantoio, cuttings were collected and treated with 0 mg.L and 2500 mg.L of indolebutyric acid (iBa) by immersion in the base of the cuttings. after 60 days of plantin...

A test mixture of five phytohormones [naphthaleneacetic acid (NAA), naphthoxyacetic acid (NOA), indoleacetic acid (IAA), indolebutyric acid (IBA), and indolepropionic acid (IPA)] was investigated. These compounds were cleanly separated with good resolution by capillary zone electrophoresis with a UV diode array detector using 20 mM sodium phosphate buffer (pH 7.25). The lowest detection limit w...

An efficient protocol was developed for high frequency plant regeneration from leaf explants of Ammi majus. Ammi majus L. (Apiaceae) is a herb of pharmaceutical as well as ornamental interest and used in the treatment of leucoderma. Since in Ammi majus the seed set and germination is poor attempts were made to propagate the plants through tissue culture. The callus from cotyledonary leaves obta...
