Cabbage transplants growth and development influenced by tretment with Rivergreen

Cilj ovog istraživanja bio je utvrditi učinak tretmana s Rivergreen – om® na rast i razvoj presadnica kupusa. Rivergreen® je novi proizvod dobiven mljevenjem i tribomehaničkom aktivacijom kamenog sedimenta rijeke Drave. U istraživanju je korišteno sjeme kupusa sorti Varaždinski i Bijeli futoški domaći te je praćen rast i razvoj kupusa do faze presadnica. Nakon sjetve, biljke su rasle u klima komoru sa 16 h svjetlosti i 8 h tame. Izmjereni su pojedini morfološki parametri presadnica nakon završetka pokusa i to visina stabljike, broj, dužina i širina listova kao i svježa i suha masa nadzemnog dijela. Nakon obrade podataka utvrđeno je da su svježa i suha masa obje sorte bile značajno veće kod biljaka tretiranih s Rivergreen®-om. Visina stabljike do prvog grananja kod obje sorte nije bila pod utjecajem tretmana s Rivergreen – om® kao ni broj i širina listova sorte Varaždinski kupus. Broj listova sorte Bijeli futoški domaći bio je pod utjecajem tretmana te je bio značajno veći kod tretiranih presadnica. Širina listova navedene sorte nije bila pod utjecajem tretmana. Sorta Varaždinski kupus razvila je značajno duže listove u slučaju tretmana s Rivergreen®-om dok tretman s Rivergreen®-om nije utjecao na dužinu listova sorte Bijeli futoški domaći. Iz navedenog se može zaključiti da Rivergreen® ima utjecaj na pojedina morfološka svojstva te pozitivno utječe na razvoj biomase presadnica kupusa što je preduvjet za optimalni rast i razvoj biljke te konačno prinos, ali je potrebno naglasiti da je odgovor biljke na tretman s Rivergreen®-om strogo ovisan o sorti tj. biljnoj vrsti.The aim of this study was to determine the effect of treatment with Rivergreen® on growth and development of cabbage seedlings. Rivergreen® is a new product obtained by milling and tribomechanical activation of the Drava river rock sediment. The seeds of two cabagge cultivars were used in this study, cv. Varaždinski and cv. Bijeli futoški domaći. Growth and development of cabbage was monitored until the stage of transplants. After sowing, the plants grew in the climate chamber with regime of 16 hours of light and 8 hours of darkness. Certain morphological parameters of the transplants were measured after the experiment was completed, namely the stem height, the number, -length and width of the leaves as well as the fresh and dry weight of the aboveground part. After statistical analysis of data, it was concluded that fresh and dry mass of both varieties was significantly higher in plants treated with Rivergreen®. Stem height in both varieties was not affected by the treatment with Rivergreen® as well as the number and width of leaves of the cv. Varaždinski. The number of leaves of the Bijeli futoški domaći was under the influence of the treatment and was significantly higher in treated plants. Further, the leaf width of the specified variety was not affected by the treatment. Cv. Varaždinski developed significantly longer leaves in the case of Rivergreen® treatment, while Rivergreen® treatment did not affect the length of the other cultivar. At the end, it can be concluded that Rivergreen® has an effect on certain morphological properties with positive influence on the development of cabbage transplants biomass that is a prerequisite for optimal growth and development of the plant and finally yield. However, it should be emphasized that the plant response to Rivergreen® strictly depends on variety or plant species
