Types of ventilation
Numbers of air exchange (NAE) or Flow rate (FR)
Brass ica oleracea L.
Forced ventilation; non- FR = 5 ml min"
mechanized humidity induced NAE = 5 h"1 pressurized forced flow system compared with natural ventilation (polypropylene disc) and airtight vessel in a 60 ml vessel;
Brassica oleracea L.
FR = 1-5 ml min"1 in a 60 ml vessel; NAE = 5 h"1
Forced ventilation; non-mechanized humidity induced pressurized forced flow system compared with natural ventilation (polypropylene disc) and airtight vessel
Natural ventilation; Suncap Not measured closer (grown photoautotrophically) compared with polyethylene disc (sugar containing medium; control)
Forced ventilation enhanced Zobayed et al., growth and chlorophyll 1999a content, flushed-out accumulated ethylene, enhanced CO2 concentration, provide atmospheric O2 in the headspace under forced ventilation
Shoot culture Zobayed et al.,
(organogenesis): growth and 1999b chlorophyll content increased, flushed-out accumulated ethylene, enhanced CO2
concentration, provide atmospheric O2 in the headspace
Photoautotrophically grown Cristea et al., plants with natural ventilation 1998
showed higher growth, multiplication, chlorophyll and carotenoids, Chi a/b ratio, net photosynthetic rate, ribulose - 1, 5-bisphophate, carboxylase/ oxygenase and phosphoenolpyruvate carboxylase activities than control
