Mineral nutrition and adventitious rooting in microcuttings of Eucalyptus globulus.
We characterized the adventitious rooting response of Eucalyptus globulus Labill. to various concentrations of calcium, nitrogen, phosphorus, iron, manganese, zinc, boron and copper. The parameters analyzed were percent rooting, root number, root length and mean rooting time. Root number and root length were significantly affected by mineral nutrition, whereas mean rooting time and rooting perc...
متن کاملEvents Associated with Early Age-Related Decline in Adventitious Rooting Competence of Eucalyptus globulus Labill
The development of adventitious roots is affected by several factors, including the age of the cutting donor plant, which negatively affects rooting capacity. Eucalyptus globulus quickly loses rooting capacity of cuttings as the donor plant ages, although the molecular and biochemical mechanisms behind this process are still unclear. To better understand the bases of rooting competence loss in ...
متن کاملExpression of auxin carrier genes during adventitious rooting in Eucalyptus globulus
Background Eucalyptus globulus and its hybrids are important for the cellulose and paper industry, mainly due to their relatively low lignin content. However, rooting of cuttings of this species is often recalcitrant and exogenous auxin application is necessary for adventitious root development. Auxin plays a central role in rooting capacity, which is particularly affected by its endogenous con...
متن کاملEucalyptus Globulus
"The authentic facts, relating to the remarkable power of the Eucalyptus Globulus in drjing marsh lands and rendering them healthy, are such as to deserve serious and general attention. It appears to be certain that where the Eucalyptus prospers intermittent fever disappears. This tree grows with incredible rapidity, absorbs ten times its own weight of water in twentyfour hours, and spreads thr...
متن کاملChemical screening for promotion of adventitious root formation in Eucalyptus globulus
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...
