The Beneficial Effects of Soluble Silicon Fertilizer in <i>Dendrobium</i> Orchids: Silicon-Augmented Resistance against Damage by Insect Pests and Fungal Pathogens.

It is important to note that the leaf temperature between treated and control plants was marginally significant at (α = 0.10, F = 2.91, df = 1, 174, p = 0.0897), and the Si-treated plants had a consistently lower leaf temperature for the majority of the five weeks we collected data; however, that difference ranged from 0.5–1 °C depending on variety ( Figure 9 ).
