Zusammenfassung, Abstract
Three isolates of different Trichoderma species were selected for this study. T. hamatum (LU592) and T. harzianum (LU686), were known to stimulate growth and improve establishmentof P. radiata seedlings, and T. atroviride (LU132) had no stimulatory activity. The ability of theseisolates to establish and survive in bulk soil, the rhizosphere, rhizoplane or endorhizosphere of P. radiata seedlings was determined. In addition, the effect of each isolate on P. radiata seedling development and growth was assessed and is currently being confirmed in a large scalecommercial experiment. From the nursery experiment, the Trichoderma isolate which was themost effective at colonising all P. radiata root subsystems (LU592) was selected for moredetailed ecological studies using genetically marked strains. Current experiments are focussedon the spatial dynamics of Trichoderma within the rhizosphere of P. radiata. The implication ofthe results in relation to the use of Trichoderma bio-inoculants in the nursery will be discussed.
