Abstrakt
Aed-iluürti kasvatatakse suvelillena lillekastides, amplites ja pinnakatjana. Tegemist on
hinnatud taimega, sest õitseb terve suve ning ei vaja erilist hooldust. Kuna tänapäeval on
aina suurem nõudlus ilutaimede järele ning lillede kasvatamiseks kasutatakse suurtes
kogustes mineraalväetiseid. Mineraalväetiste kasutamine reostab looduskeskkonda ning
nende alternatiiviks sobiks kasutada biostimulante, mis on keskkonnasõbralikumad ja
jätkusuutlikumad, parandades taimede kasvu, õitsemist ja taimede vastupanu stressile.
Erinevad katsed on näidanud biostimulantide positiivseid tulemusi ilutaimede toitainete
omastamise, kasvu ja õitsemise parandajana.
Antud uurimistöö eesmärk oli välja selgitada biostimulantide Allgrow ja Basfoliari mõju
aed-iluürdi (Glandularia x hybrida) sordi Lanai `Scarlet with Eye` õitsemisele.
Saadud tulemustest saab järeldada, et katses kasutatud biostimulandid Allgrow ja
Basfoliar soodustasid oluliselt taimede õisikute teket, omades mõlemad läbi
katseperioodi positiivset mõju taimede õitsemisele. Lehtede SPAD-näidule oli oluline
mõju Allgrow variantidel ning Basfoliari mõju jäi tagasihoidlikuks ja varieeruvaks.
Biostimulantidega kastetud taimedel oli rohkem õisi, substraadi elektrijuhtivus ja SPADnäit paremad.
Glandularias are valued summer flowers because they do not need much care and bloom all summer long. Different trials with ornamental plants have shown that biostimulants have a beneficial effect on plants, improving their growth, flowering and stress tolerance. Biostimulants are a good environmentally friendly alternative to reduce the use of mineral fertilizers. The aim of the current study was to find out the effect of two different biostimulants (Allgrow and Basfoliar Aktiv) on the flowering of clandularias (Glandularia x hybrida) cultivar Lanai `Scarlet with Eye`. This research was conducted in Kanepi Aiand OÜ. The results show that Allgrow and Basfoliar promoted the formation of plant inflorescences. Allgrow variants had a significant effect on leaf SPAD reading, and the effect of Basfoliar remained modest and variable. Based on the results of this study, the use of biostimulants can be recommended, as the plants watered with biostimulants bloomed more, the electrical conductivity of the substrate and the content of the SPAD reatments were better compared to control variant.
