| Abstract (English): |
In the research on the influence of nanoparticles on plants, it is important to identify both the optimal concentrations of nanoparticles and the growing stage in which the plant is sensitive to a certain type of treatment. The study on the influence of nanoparticles on hyacinth bulbs was carried out in an experiment in which 4 treatment variants were used simultaneously, each variant having 3 repetitions. Two solutions with different concentrations of gold nanoparticles in chitosan (25 and 50 µg/mL) were used as treatment, and the samples in which either a chitosan solution or water was administered were considered as controls. To each hyacinth bulb, 2 ml of a certain solution was applied. Thus, the aim was to improve the sprouting of hyacinth bulbs and of biometric indicators such as hyacinth height, number of leaves and percentage of flowering. It has been observed that the nanoparticle treatments act differently depending on the growing stage of the plant. From the analysis of the results we can state that the treatment with gold nanoparticles in a concentration of 50 µg/mL is good for stimulating the plant growth, but it is not effective in their development, the most suitable solution as a treatment being that of gold nanoparticles in a concentration of 25 µg/mL.

| Abstract (Romanian): |
În cercetările privind influența nanoparticulelor asupra plantelor este foarte important să identificăm atât concentrațiile optime de nanoparticule, cât şi fenofaza în care planta este sensibilă la un anumit tip de tratament. Studiul privind influența nanoparticulelor asupra bulbilor de zambilă s-a desfăşurat în cadrul unui experiment în care s-au folosit concomitent 4 variante de tratament, fiecare variantă având 3 repetiții. Ca tratament au fost folosite două soluții cu concentrații diferite de nanoparticule de aur în chitosan (25 şi 50 µg/mL), iar ca martori au fost considerate eşantioanele la care s-a administrat fie o soluție de chitosan, fie apă. Fiecărui bulb de zambilă i s-au aplicat câte 2 ml dintr-o anumită soluție. Astfel, s-a urmărit îmbunătățirea încolțirii bulbilor de zambilă şi a unor indicatori biometrici precum înălțimea zambilelor, numărul de frunze şi procentul de înflorire. S-a observat că tratamentele cu nanoparticule acționează diferit în funcție de fenofaza plantei. Din analiza rezultatelor putem afirma că tratamentul cu nanoparticule de aur în concentrație de 50 µg/mL este bun pentru stimularea creşterii plantelor, însă nu este eficient în cazul dezvoltării acestora, cea mai potrivită soluție ca tratament fiind cea de nanoparticule de aur în concentrație de 25 µg/mL.
