Production temperature affects leatherleaf fern postharvest desiccation
Leatherleaf fern [Rumohra adiamtiformis CForst.) Ching] was grown in controlled environment chambers set for day/night temperatures of 35/24C (high temperature regime, HTR) or 24/13C Clow temperature regime, LTR). Fronds were harvested for vase life studies at 1100 and 1800 HR and held in holding rooms in deionized water. Plants were then moved to a greenhouse environment (16-25C) and, after 1 week, an additional set of fronds were harvested. (...)
