e0“In PF(A) in 2008, flowering from 30 (70.6% treated stalks) vs 60 s/d (65.9%) and 30 vs 45 s/d (77.1%) developmental declinations were not significantly different but was for the 45 vs 60 s/d declinations.”

- Intervention effect In 2007 there were no differences among photoperiod treatments in flowering.
- Observation In 2007 clones flowered at 87.9% and 84.4% across the two experiments.
- Observation In 2007 treated stalks produced usable panicles at 62.3% and 56.7% across the two experiments.
- Observation In 2007 stalks were IBNE at 20.0% and 19.4% across the two experiments.
- Intervention effect In PF(A) in 2008, the 30 s/d developmental declination did not differ from 45 s/d in flowering (77.1%).
- Intervention effect In PF(A) in 2008, the 45 s/d developmental declination differed significantly in flowering from 60 s/d.
- Observation In PF(A) in 2008, meristems initiated but not emerged averaged 23.8%.
- Observation In PF(A) in 2008, on average 90.1% of clones flowered.
- Intervention effect In PF(B), the 45 and 30 s/d declinations did not differ in flowering, with 85.5% of treated stalks flowering at 45 and 30 s/d and 92.5% of clones flowering.
- Observation In PF(B) the control (60 s/d) produced an anomalous flowering result.
- Intervention effect In 2009 the 60/20 s/d declinations disappointed, with 52.8% of stalks and 74.4% of clones flowering.
- Intervention effect In 2009 the 60/60 s/d control and 40/40 declinations did not differ significantly, with 78.5% of stalks flowering.
- Intervention effect The 40 s/d regime gave 81.6% flowered stalks, the best flowering result yet achieved.
- Observation The 40 s/d regime gave 14.7% meristems initiated but not emerged.
- Intervention effect Pollen fertility differed significantly among photoperiod regimes.
- Observation Pollen fertility was not a limitation for cross pollination.
- Intervention effect Managed photoperiod flowering was superior to in-field flowering, by 188% in 2008 and 669% in 2009.
- Intervention effect Mean fuzz weight of PF crosses was lower than that of core crosses.
- Intervention effect Seed germination of non-germination-tested PF crosses was equal to or better than that of germination-tested core crosses.
