Corn salad (Valerianella olitoria L.) yield response to cell size of plug trays | Vpliv velikosti celice gojitvene plošče na pridelek motovilca (Valerianella olitoria L.)

English. The research was undertaken to determine if the plug tray cell size had an impact on plant characteristics and yield of corn salad (Valerianella olitoria L.). Seeds of four cultivars ('Ljubljanski', 'Holandski', 'Flavor' and 'Masse') were sown in styrofoam plug trays with 40 cells (60 ml cell-1), 84 cells (35 ml cell-1) and 160 cells (20 ml cell-1). Plants growth generally increased with cell size, though the effect varied with different cultivars. An increase in cell volume resulted in an increase in leaves height, leaves number and leaves fresh mass, as well as percentage of dry matter. Cv. 'Holandski' was obtained the highest leaves fresh mass regardless of cell volume.

Slovenian. Raziskava je bila izvedena z namenom ugotoviti, ali velikost celice gojitvene plošče lahko vpliva na lastnosti in pridelek motovilca (Valerianella olitoria L.). Seme štirih kultivarjev ('Ljubljanski', 'Holandski', 'Flavor' in 'Masse') je bilo posejano v stiroporne gojitvene plošče s 40 celicami (60 ml/ celico), 84 celicami (35 ml/celico) in 160 celicami (20 ml/celico). Na splošno je bila rast rastlin intenzivnejša z večanjem prostornine celice, medtem ko so se kultivarji različno odzivali na velikost celic. Večji volumen celice se je izrazil v večjih listih, večjem številu listov, večjem pridelku listne mase, prav tako pa tudi v večjem deležu suhe snovi. Cv. 'Holandski' je dal največji pridelek zelene listne mase ne glede na prostornino celic.
