Tissue culture plugs of  Aglaonema  `Cory', `Maria', and `Silver Queen' and  Dieffenbachia  `Panther', `Snowflake', and `Sport Lynn' were potted singly in 15-cm pots and grown in a shaded greenhouse under a photosynthetic irradiance (PI) of 100 mmol·m –2 ·s –1 . Eight months after potting, 27 plants of each cultivar were placed in nine interior evaluation rooms under three different PI levels (three rooms per level): 4, 8, and 16 mmol·m –2 ·s –1 . In addition, three plants of each cultivar were maintained in the original greenhouse for the duration of the experiment. Number of leaves, plant height and width were monitored monthly. Recently matured leaves were removed at 3-month intervals for 9 months for determination of fresh and dry weight, leaf area, and percentage leaf variegation. Variegated leaf area was assessed using digitized leaf images. Interior PI levels affected growth parameters, but the degree of response was cultivar-dependent. Smallest leaves developed on plants grown under 4 mmol·m –2 ·s –1  and largest leaves developed under 16 mmol·m –2 ·s –1 . Leaf area of  Dieffenbachia  `Sport Lynn' showed the greatest response and  Aglaonema  `Maria' the least response to PI levels. Percentage leaf variegation of  Dieffenbachia  `Snowflake' was least affected and  Dieffenbachia  `Sport Lynn' was most affected by PI levels. Fresh leaf weight of unit area decreased as PI levels decreased from 16 to 4 mmol·m –2 ·s –1 , however, the decrease in unit area was most pronounced in cultivars that maintained the highest quality ratings. Based on the results of this study,  Aglaonema  `Maria' and  Dieffenbachia  `Snowflake' had the most satisfactory interior performance within their respective genera.
