Figure 7.

Total inflorescence dry weight responses (g/plant) to 12 h (filled bars) and 13 h (empty bars) photoperiod treatments of C. sativa cultivars ‘Incredible Milk’ (IM) and ‘Gorilla Glue’ (GG). Total inflorescence dry weight was calculated by adding nonapical inflorescence dry weight (oven-dried) and apical inflorescence dry weight for each plant. Data are means ± SE, n = 3. Error bars are presented for all data but may be obscured for small SE values. Percentage values marked in the 13 h bars signify the increase in total inflorescence dry weight relative to the 12 h treatment, and the p-values above each cultivar represent the significance level of the comparison of means according to Student’s t-test.
