Role of Silicon on Growth, Relative Water Contents and Uptake of Silicon, Calcium, and Potassium in Appletree

Growth performance, relative water contents (RWC), and mineral nutrition were studied in the apple tree (Arkansas Black) treated with different concentrations of silicon (25, 50, 100, 200, 400, and 800 ppm). Lower administrations of silicon (25–200 ppm) enhanced relative yield, relative water contents, calcium, and potassium contents. A significant (0.1% level) direct relationship between tissue silicon content and applied silicon concentrations were observed. Shoots were significantly richer in silicon content than roots. The results indicate a possible requirement of silicon for higher plants.

Based on the above information, the technology of CALISTA provides a good source of necessary elements to help the plants resist adverse conditions and improve nutrient uptake.

Furthermore, to the beneficial effects of Si, Wang et al., 2021, in a research paper in a horticulture journal, reported that Si treatment increases rice yield and growth parameters when plants are suffering under drought conditions.

The application of CALISTA is an attractive approach to improving plant water status and maintaining plant water balance under drought stress conditions.

Understanding the interactions between Ca and Si application will contribute to more efficiency of CALISTA, which enhances plants’ stress tolerance and improves nutrient uptake.
