All cosmos plants flowered under all treatments. Plants grown under all NI lighting treatments formed the first VB and flowered similarly as those grown under the SD, indicating this cultivar is day neutral (Table III-3). Extension growth under all NI lighting treatments was similar to that under the SD, but cosmos plants grown under W, B+R, B+FR, and R+FR NI were approximately 4 cm taller than those grown under the B NI. There was no effect of photoperiod treatment on VB number or leaf number. All dahlia ‘Leanne’ plants flowered under all NI lighting treatments, but flowering percentage under the SD was 100% and 20% in the first and second replications, respectively (data not shown). Compared with the SD, all NI lighting treatments except the B NI delayed VB appearance by 6 to 12 d and flowering by 7 to 13 d (Table III-3). ‘Leanne’ plants grown under the B+R and B+FR NI flowered 5 and 6 d later, respectively, than those grown under the B+R+FR NI. At flowering, plants were tallest under treatments emitting FR light (i.e., the INC, B+FR, B+R+FR, and R+FR NI), and those under the B NI and SD were shortest. Plants grown under all NI lighting treatments except the B NI had approximately two more VBs than those grown under the SD. The increase in leaf number of ‘Leanne’ at flowering showed a similar treatment response as flowering time, developing the most and fewest leaves under the B+FR NI and SD, respectively. No dahlia ‘Gallery Pablo’ plants flowered under the SD, and all plants flowered under all NI lighting treatments except the B and B+FR NI (data not shown). Flowering percentage was 0% and 11% under the B NI and 11% and 67% under the B+FR NI in the first and second replication, respectively. The B+R+FR NI slightly delayed VB appearance compared to the other treatments emitting R light. ‘Gallery Pablo’ plants grown under the B+R+FR NI flowered 5 d later than those grown under the R+FR NI. Plants were approximately 5 cm taller under treatments 69
