Even though the Lavandula species may be propagated by seeds, it should not be the preferred propagation method because it causes a great lack of uniformity. On the other hand, asexually propagated lavender crops would provide more homogeneous crops, and clones from high quality plant material would increase the odds for obtaining a higher quality essential oil. However, problems such as poor r...

in this research, possibility of bulblet production from different cuttings including leaf, leaf-bud and leafy-stem of lilium oriental hybrid cv. ‘star gazer’ evaluated under different levels of indole-3-butyric acid (iba) with 0, 250, 500, 750 and 1000 mg per liter (ppm). the cuttings were taken from stems which grown from cold treated bulbs in early october. a factorial experiment was done in...

The family Araucariaceae encompasses several evergreen forest tree species, which has a high ornamental value due to being a good specimen and having symmetrical branches. Conventional propagation of Araucaria excelsa R. Br. var. glauca by cutting has limited success because of topophysis and difficult-to-root characteristics, and grafting is accompanying incompatibility. The aim of this resear...

A suitable protocol for micropropagation of Casuarina hybrid, Casuarina equisetifolia L. 9 Casuarina glauca Sieber ex Spreng (C. e. 9 C. g.), was developed. When seeds without seed coats were cultured on 4 germination media, the optimal seed germination percentage (91%) was obtained on 0.8% agar solidified water medium. Shoot multiplication was achieved by culturing 2-cm long epicotyls, excised...

ABSTRACT This study aimed to establish a methodology for vegetative propagation via mini-cuttings technique Mimosa Caesalpiniifolia. For such, three independent experiments were conducted: the first one evaluated survival and production of mini-stumps; second tested interaction between types (apical intermediate) different concentrations indolbutyric acid (IAB; 0, 2,000, 4,000 6,000 mg.L-1) on ...

Eucalyptus globulusis one of the most profitable trees for pulp and paper industries due to its fast growth and short harvesting cycle. This species is easily pulped with high yield, and its fiber qualities are among the best for paper production. However, it is difficult to vegetatively propagate E. globulus.So far, we have developed “photoautotropic culture method” that promotes rooting perce...

To evaluate the rooting of New Giunea impatiens (Impatiens hawker stem) cuttings under arbuscular mycorrhiza (Glomus mosseae) and its effect on nutrient elements absorption, an experiment as factorial in complete random design with three replications in the greenhouse was established. Experiment factors were four levels of synergistic mycorrhiza in 0, 11 and 22 percent (as powder) and 20 percen...
