Effect
Phylgreen + Delfan Plus V treated Peace Lily, cv. Alfetta/Lima, grown in a peat-based substrate was after 3 repeated drougth stress cycles on average 2.4 % shorter and had on average 3.2 % broader leaves, 0.3 % longer leaves, 1.1 % less fresh weight, 0.3 % more dry weight and 4 % more root development, during drought stress no significant effect on the stomatal conductance compared to the untreated control grown in the same drought stress conditions. Only negative significant effect on plant height of cv. Lima. The effect on the total chlorophyll content and the total phenolics content varied between the different drought cycles and cultivars; Phylgreen + Delfan Plus V lowerd the total chlorophyll content of cv. Alfetta after drought stress and lowered the total phenolics content of cv. Lima after drought stress compared to the untreated controls.
