Stabilized shoot cultures initiated from crown material of six adult Quercus robur L. trees and from basal epicormic shoots of a Quercus rubra L. tree showed good in vitro rooting capacity. An initial five-day dark period generally improved the rooting response but was detrimental to plantlet quality. There were clonal differences in rooting capacity. The concentration and exposure time of the ...

Studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as Henna. The purpose of this study is to determine an appropriate concentration of Naphthalene Acetic Acid (NAA), Indole Butyric Acid (IBA) and salicylic acid (SA) on Rooting of Henna. Present study showed that there was a great variation in most of the measured characters at P<...

Ficus benjaminais a very popular and resistant indoor plant in temperate areas. Cutting is the easiest propagation method of this plant and it requires special treatments such as auxin and appropriate rooting medium. In order to test the suitable auxin (IBA) concentration and rooting media, a factorial experiment carried out based on randomized complete block design with three replications. Exp...

In vitro rooting and the acclimatization of micropropagated rootstocks of apple trees is essential for plant development in the field. The aim of this work was to assess the use of rhizobia of Adesmia latifolia to promote rooting and acclimatization in micropropagated Marubakaido apple rootstock. An experiment involving in vitro rooting and acclimatization was performed with four strains of rhi...

Course Managers and greenkeepers are well aware of the deleterious aspects of excess thatch: Increased disease and insect problems, localised dry spots, chlorosis of the turf, proneness to scalping, foot printing, decreased heat, cold and drought hardiness, restricted rooting, nitrogen immobilization, reduced effectiveness of pesticides, a soft, spongy surface in wet weather, and the potential ...

Peroxidases play a major role in several physiological processes. Specifically, in vitro activity of this enzyme was used as a marker to identify different rooting phases of Nothofagus. The study of peroxidase profile patterns during rhizogenesis in this genus could give additional information about this topic, to justify the use of peroxidase isoforms as a more specific biochemical marker than...

one of the fundamental processes in woody plant propagation especially olive is rooting ability of cuttings. thus the selection of superior trees with desirable genetic structure is essential. adventitious root formation is a key step in rooting ability. therefore, identification of inducible genes in these processes is necessary. in this study, for the first time importin genes were identified...

Rooting phylogenies is critical for understanding evolution, yet the importance, intricacies and difficulties of rooting are often overlooked. For rooting, polymorphic characters among the group of interest (ingroup) must be compared to those of a relative (outgroup) that diverged before the last common ancestor (LCA) of the ingroup. Problems arise if an outgroup does not exist, is unknown, or ...

Progress and problems in vegetative propagation of important North American hardwoods are reviewed with emphasis on rooting cuttings and the application of propagatIOn t~'hniqucs in breeding research. Some problems in rooting physiology are diS('u,;",>.
