ABSTRACT
The ultra-high dilutions (UHDs) can be used for decreasing stress conditions causing by climate variations. The present research investigated the effects of ultra-highdilutions (UHDs) on some ornamental plants, germination, and hormonal variations.Methods:
In order to study the effect of UHDs (Calendula officinalisCalen. andArnica montanaArn.) on the physiological, primary metabolite, and hormonal variations of theOryza sativa L. (rice), 104 experiments were designed and statistically analyzed using the Design Expert 7.0.1 software over the general factorial design methodology. Two qualitative factors, including the UHDs/placebo usage and the type of plant usage, and two quantitative factors, including temperature and irrigation, were studied. The validated analysis was subjected to more extended studies on the variations in physiological growth, carbohydrate, protein content, and levels of plant hormones, including gibberellic acids, indole acetic acid, abscisic acid, and salicylic acid.Results:
The statistical analysis resulted in a prediction model which was more than 75% correlates with experimental results. The results showed that the UHDs increased the carbohydrate and protein content of seedlings. Also, compared to placebo, the levels of hormones GA3 and IAA in all samples increase, and the amount of GA4 decreases. The amount of ABA and SA hormones inS. officinalisincreased under UHDs treatment while decreasing in the other two samples.Conclusion:
The use of UHDs leads to an increase in the production of carbohydrate and protein content. Moreover, it causes significant variations in the growth-inducing hormone and increases the tolerance of seeds under higher/lower temperatures and draught/drowning. The results of this study open up a window to reduce germination survival and increase their resistance to sudden climate change.Palavras-chave
