Primjena endofitnih Fusarium gljiva za poboljšanje rasta vinove loze | Application of endophytic Fusarium fungi for growth improvement of wine grape

Croatian. Endofitni organizmi se sve više primjenjuju u ekološkoj proizvodnji i zaštiti biljaka. Najčešće se radi o gljivama i bakterijama koje se apliciraju na biljke kao biološka sredstva za poboljšanje rasta i otpornosti na biljne bolesti. U našem istraživanju preliminarno smo ispitali utjecaj dva izolata gljive Fusarium solani na porast vinove loze sorte Kardinal i Lavalle. Vinova loza je tretirana sa suspenzijom gljive u stadiju pupa. Dva mjeseca nakon umjetne infekcije izmjerene su karakteristike vinove loze: dužina stabljike te dužina, širina i broj listova. Utvrđen je značajan pozitivan utjecaj endofitnih gljiva na dimenzije stabljike i lista. Zaključili smo da endofitne gljive pozitivno djeluju na ukupno zdravstveno stanje biljke što indirektno smanjuje mogućnost pojave bolesti jer su biljke otpornije.

English. Endophytic organisms are increasingly being used in organic production and plant protection. The most common are fungi and bacteria which are applied to plants as biological agents for improving growth and resistance to plant diseases. In our research we preliminary examined the influence of two isolates of Fusarium solani on the growth of the grapevine varieties Cardinal and Lavalle. Wine grapes were treated with a fungal suspension in bud stage. Two months after the artificial infection the characteristics of the wine grape were measured: length of the stem and length, width and number of leaves. Significant positive effect of endophytic fungi on the size of the stem and leaf was determined. We concluded that endophytic fungi positively affect the overall health of the plant, which indirectly reduces the possibility of disease because the plants are more resistant.
