Abstract:
... Globally the demand for forestry resources is booming, and consequently innovative approaches to cultivate valuable hardwoods, such as eucalypts, are crucial. Although micropropagation offers a means to clonally propagate desirable cultivars, this technique is often variety-specific for eucalypts. Thus, recalcitrant genotypes are often excluded from micropropagation programmes as development requi ...

Fusarium circinatum; Pinus patula; Pinus tecunumanii; bags; bark; forests; growing media; hybrids; hydroponics; mortality; pathogens; sand; vegetative propagation; South Africa
Abstract:
... In response to the Fusarium circinatum pine pathogen threat in southern Africa, research has been conducted on the development of F. circinatum- tolerant P. patula and P. patula hybrids. The objective of this study was to investigate the propagation potential of these taxa in two vegetative propagation systems, hydroponic sand beds and polythene bags with composted pine bark growing medium. Signif ...

Abstract:
... Fusarium circinatum is a pathogen causing serious post-planting mortality of Pinus patula seedlings in southern Africa. Containerised planting stock that is asymptomatic but associated with F. circinatum in the nursery is thought to be the cause of this problem. The aim of this study was to determine if re-use of seedling containers could be a source of inoculum resulting in asymptomatic planting ...

Fusarium circinatum; Pinus patula; forestry; forests; fungi; inoculum; mortality; pathogens; plant establishment; seedlings; water stress; South Africa
Abstract:
... Fusarium circinatum is an important fungal pathogen of Pinus species. In South Africa, it is the most significant pathogen of Pinus patula seedlings in forestry nurseries where it presents a substantial constraint to productivity and can continue to cause mortality in-field for up to two years after establishment. This study describes the results from two trials where P. patula seedlings were inoc ...
