Growth and Flowering Responses of Cut Chrysanthemum Grown under Restricted Root Volume to Irrigation Frequency

Table 1

Effect of substrate volumes on chlorophyll fluorescence efficiency (Fv/Fm) and chlorophyll content.

Substrate volume (cm^3)	73	140
Fv/Fm	0.68^a	0.73^a
Chlorophyll content	53.25^a	53.99^a

Values in each column accompanied by different letters differ significantly at by Tukey’s test.
