Variação termal da água ultra diluída na germinação de sementes

Abstract

Seeds change their germination for different reasons, and this includes the variation in water temperature. There are several causes of temperature change, which may affect the quality of germination. Reflecting on this, this research studied the variation in the temperature of the germination water after administering substances from five different homeopathies. The research was carried out at the Plant Production Laboratory of the Agronomy Course at UNISUL in Tubarão, Santa Catarina. Measurements of water temperature, used for soaking arugula seeds (Eruca sativa L.). were taken for 48 minutes, monitored and recorded with a FlirOne Pro® thermal camera. Monitoring was carried out after freezing 6 glass containers containing 20 mL of water in which 0.0625 mL of the homeopathies were added: Arnica montana 11cH; Belladona officinalis 11cH; Sepia officinalis 14cH; Silicea terra 5cH; Sulfur 9cH e, a control treatment, containing 20 mL of distilled water plus 0.0625 mL of 70% alcohol. After measuring the temperatures, 30 arugula seeds were placed in each container with the treatments for 14 hours (priming). Germination was recorded by near infrared images, Mobius 1080® webcam. Statistical design comprised 6 treatments and 3 replications, completely randomized, ANOVA and Tukey test. It was concluded that the differences observed in the thermal images were significant among themselves, and the control treatment differed from the homeopathies. The effect of Arnica montana was significant and showed the lowest reaction temperature in the water, the highest vegetation index and the highest percentage of germination.
