Abstract

Trichoderma vrste se u svijetu koriste već duži niz godina u poboljšanju rasta i razvoja biljaka.Pokazale su se i vrlo uspješne u zaštiti biljaka protiv bolesti.Polazeći od činjenice da su Trichoderma vrste polučile izvrsne učinke na rast rajčice,arnike i salate.Dana 14. listopada 2015. postavljen je pokus u dvije varijante: Mikrokapsule Trichoderma virideSTP s dodatkom kalcija te netretirana kontrola.Vrsta Trichoderma viride je inkapsulirana u obliku Mikrokapsula s dodatkom kalcija te je u količini 2 grama po biljci aplicirana u zonu korijena.Mjereni parametri kod maćuhica su bili: veličina lista, dužina najvećeg lista, širina najvećeg lista, broj listova, broj cvjetova, visina biljke, širina, dužina te visina rozete.Nakon provedenih očitanja te obradom podataka Mikrokapsule STP+Ca su za razliku od Kontrole polučile lošije rezultate. Mikrokapsule STP+Ca su učinile kalcij dostupnijim biljci, ali zbog povišenog fosfora unutar supstrata vegetativni i generativni rast je izostao. Naime, došlo je do nastanka fosfatnih soli (kalcijev fosfat, kalcijev hidrogenfosfat, kalcijev dihidrogenfosfat) te je time biljka ostala daleko od optimalnih uvjeta za rast i razvoj.

Abstract (english)

Trichoderma species are used in the modern world for many years to improve plant growth and development. They have proved to be very successful in protecting plants against diseases. Based on the fact thatTrichoderma species yielded great effects on tomato, lettuce and arnica. This experiment took place on October 14th 2015 in two variants: microcapsules Trichoderma viride STP with calcium and nontreated control. T.viride was applied in the form of microcapsules in an amount of two grams per plant in the root zone. Measured parameters were: leaf size, number of leaves, number of flowers, plant height and plant diameter. After measuring and processing information microcapsules STP produced negative results.Microcapsules STP+Ca yielded a negative impact on vegetative and generative pansy growth.Thisis related to the chemical process that occured within the supstrate and prevented advanced pansy growth. It occured an emergence of phosphate salts (calcium phosphate, calcium hydroxyphosphate, calcium dihydroxyphosphate) thereby the plant remained far from optimal conditions for growth and development.
