Abstract:V sklopu magistrske naloge smo preučevali razlike v prevodnosti listnih rež in alelopatski potencial indijskega jagodnjaka (Potentilla indica (Andrews) Th.Wolf) med sončnimi in senčnimi rastlinami. Na izbranem rastišču indijskega jagodnjaka smo skozi daljše časovno obdobje s porometrom spremljali prevodnost listnih rež. Za testiranje alelopatskega potenciala indijskega jagodnjaka smo izbrali test kalitve s semeni vrtne kreše (Lepidium sativum L.). Slednje smo za 4 dni izpostavili različnim koncentracijam vodnih izvlečkov sončnih in senčnih listov (0,1 %, 1 %, 5 %, 10 %). Na podlagi deleža vzkaljenih semen in rasti radikule in hipokotila smo ugotovili, da vodni izvlečki listov indijskega jagodnjaka močno vplivajo na kalitev semen, medtem ko na rast vrtne kreše nimajo takšnega vpliva. Z naraščanjem koncentracije vodnih izvlečkov listov indijskega jagodnjaka se je delež vzkaljenih semen zmanjševal. Razlike v alelopatskem potencialu sončnih in senčnih rastlin niso bile tako očitne kot smo pričakovali. Smo pa opazili sezonsko nihanje alelopatskega potenciala. Ugotovili smo, da je ta bil najnižji v času, ko so bili prisotni plodovi. Razlike med sončnimi in senčnimi rastlinami pa so bile bolj opazne pri merjenju prevodnosti listnih rež. Ta je bila skozi celotno raziskavo višja pri sončnih rastlinah. Ugotovili smo tudi, da prevodnost listnih rež pada z naraščajočo temperaturo in svetlobnim sevanjem ter narašča s povečevanjem vlage tal.

Title:Transpiration and allelopathic potential of sun and shade plants of Indian strawberry (Potentilla indica (Andrews) Th.Wolf)
Abstract:As part of the master's thesis, we investigated differences in the stomatal conductance and allelopathic potential of sun and shade plants of Indian strawberry (Potentilla indica (Andrews) Th.Wolf). Stomatal conductance was monitored at the selected location using a porometer over an extended period of time. To test the allelopathic effects of Indian strawberry, we conducted a germination test with garden cress seeds (Lepidium sativum L.). The seeds were exposed to different concentrations of leaf water extracts (0.1%, 1%, 5%, 10%) for 4 days. Based on the percentage of germinated seeds and the growth of radicle and hypocotyl, we found that leaf water extracts of Indian strawberry strongly influence seed germination, while they do not have such an effect on growth. The percentage of germinated seeds decreased with increasing concentration. Differences in the allelopathic potential of sun and shade plants were not as pronounced as expected. However, we observed seasonal variations in the allelopathic potential. We found that it was the lowest in fruiting stage. Differences between sun and shade plants were more evident in measuring stomatal conductance. Throughout the study, stomatal conductance was higher in sun plants. We also found that stomatal conductance decreases with increasing temperature and light radiation, while it increases with increasing soil moisture.
