Abstract
Astrid on ilutaimed, mida kasvatatakse kõige rohkem koduaedades. Katsed on näidanud, et biostimulandid aitavad parandada taimede kasvu ja õitsemist. Suurenev huvi looduslike toodete ja keskkonna hoidmise vastu toob esile vajaduse kasutada ka ilutaimede tootmisel looduslikke väetisi. Antud uurimustöö eesmärk oli välja selgitada kolme erineva biostimulandi (Allgrow, Basfoliar Aktiv ja Delfan Plus) mõju amellastri (Aster amellus L.) sordi 'Rudolf Goethe' kasvule ja õitsemisele. Saadud tulemustest saab järeldada, et Basfoliar ja Allgrow soodustasid oluliselt taimede kasvu ja õite ning õiepunga teket. Läbivalt oli katse perioodil oluline positiivne mõju SPAD-näidule Delfanil ja Basfoliaril, kuid katse lõpuks usutav erinevus biostimulantidel NPK-ga puudus. Allgrowga kastetud taimedel oli lehtede mineraalelementide sisaldus kõige lähemal optimaalsele normile.
 
Asters are ornamental flowers that are mainly grown in home gardens. Different trials with ornamental plants have shown beneficial effects of biostimulants on plant growth and flowering. The growing interest in natural products and the protection of the environment highlights the need to use natural fertilizers also in floriculture. The aim of the current study was to determine the effect of three different biostimulants (Basfoliar, Aktiv and Delfan Plus) on growth and flowering of Michaelmas daisies ( Aster amellus L.) cultivar 'Rudolf Goethe'. Based on the results it can be concluded that Basfoliar and Allgrow significantly increased plant growth and flowering. Throughout the experiment, Delfan and Basfoliar significantly increased the SPAD value. However, at the the end of the experiment there was no significant differences with control in SPAD value. Plants treated with Allgrow, had near optimum leaf mineral content.
