Abstract
Among the 48 fern taxa native to Maule Region, Chile, Blechnum cordatum, B. magellanicum and Equisetum giganteum are species with potential to be used as cut foliage.
Harvested fronds were placed in three treatments: citric acid pH 3, citric acid pH 3 + sugar (2 g/L) and control (distilled water), with five repetitions.
Foliage was placed in a chamber with 20°C and 50% relative humidity.
The water consumption and postharvest number of days were measured. Blechnum cordatum and B. magellanicum showed the longest vase life in citric acid pH 3 (7.4 and 10.2 days respectively) and also the highest water uptake.
In E. giganteum, the longest vase life (8.8 days) and highest water uptake (170 ml) were observed in the control treatment.
The results showed that citric acid helps to maintain the water uptake for longer time, which allowed B. cordatum and B. magellanicum foliage to stay hydrated. Equisetum giganteum vase life may have been longest in control treatment, because citric acid and sugar did not favor water consumption.
