Abstract
Bakalaura darba mērķis bija izmantojot dārzeņu dīgstu augšanas testu, salīdzināt no
dažādiem organiskajiem substrātiem iegūtu humīnvielas saturošu preparātu augu augšanu
veicinošo aktivitāti.
Pētījumā izmantoja četrus dažādus humīnskābju preparātus, kuri iegūti no kūdras,
sapropeļa, komposta, un vermikomposta, kā arī vermikomposta ūdens ekstraktu. Ar šiem
preparātiem dažādās koncentrācijās apstrādāja redīsu, kāļu, burkānu un tomātu sēklas un
diedzēja tās tumsā Petrī traukos piecas dienas 22 ± 2º temperatūrā un pēc tam mērīja dīgstu
hipokotilu un dīgļsaknes garumu. Tika izmantotas divas dažādas sēklu apstrādes metodes, ar
priekšapstrādi un sekojošu apstrādi vai tikai ar priekšapstrādi.
Humīnskābes saturošo preparātu augu augšanu ietekmējošā aktivitāte bija atkarīga no to
iegūšanai izmantotā organiskā substrāta. Apstrādes veids arī būtiski ietekmēja dažādu dārzeņu
kultūru dīgstu augšanu. Vislielākā pozitīvā ietekme bija novērojama vermikomposta ūdens
ekstraktam.
Bachelor's thesis was to use vegetable seedling growth test, to compare the different organic substrates for Humus substances of medicinal products containing plant growthpromoting activity. The study used five different preparations of humic acids derived from peat, sapropel, compost, vermicompost and vermicompost extract. Preparations treated with radish, swede, carrot and tomato seeds and couched them on Petri dishes for five days 22 ° ± 2 ° at room temperature, and then the measurement data was recorded. It was used five different methods for seed germination. Each method was selected for two variants of seed germination. The first variant of the first, second, third and fifth seed germination method drenched four hours at a constant concentration and preparation petri dish of the plasma concentration of the presence except for the fourth method, where the seeds were drenched for two hours at a constant concentration and preparation germinated in petri dish.
