Effect of cutting position and indole butyric acid (auxin) concentration on rooting response of Araucaria heterophylla

The effects of cutting position (tip, middle and basal) and concentration of indole butyric acid (IBA) (0, 5, 7.5 and 11 g/L) on root and shoot growth of Araucaria heterophylla were evaluated to develop a method for vegetative propagation for this tree species. Leaf number, number of adventitious roots, root length and survival rates were measured. These parameters were significantly influenced by the interactive effect...

In vitro regeneration of two grapevine (Vitis vinifera L.) varieties from leaf explants

The traditional way of grapevine (Vitis vinifera L.) propagation is time consuming and allows disease transmission from generation to generation. Moreover, it is difficult to improve this crop through conventional plant breeding methods. Therefore, the objective of this study was to develop efficient in vitro regeneration protocol for ‘Canonannon’ and ‘Chenin Blanc’ varieties of grapevine using...
