Vitality analysis of Abies n. from Christmas tree plantations after application of T.h.
Abstract
Fungal infestation of nordman fir (Abies nordmanniana) cultures leads to crop loss of up to 20 % in Austrian Christmas tree plantations. Up to now, no suitable methods for efficient combating or long-lasting inhibition of these pathogens in the run up exist. Using an ecologically compatible, directly, and easily applicable technique shall enhance the vitality of seedlings in the Christmas tree plantations, to counteract the sensitivity against plant pathogenic species and to improve the average quality of the trees. The common biocontrol fungus Trichoderma harzianum will be utilised fort his purpose. This fungus is not only known for its inhibitory effect and its repression of plant pathogens, it can also improve the vitality of plants due to its rhizosphere competence. The evaluation of an increased plant vitality after Trichoderma treatment will be investigated by the use of different established, plant-analytical methods such as determination of root collar diameter and the length of the internodes, as for instance.
