New Guinea Impatiens Flowering Express seed / Oro Farms with emphasis on 4” Production
3
Why do different lots of New Guinea Impatiens often flower differently?
5
Pot size does not affect time to flower. It is not pot size
6
Oro Farms Stock Management. We assure a stage 0 cutting with the Oro Farms technique. To avoid this problem A stage 0 cutting is essential for uniform flowering.
7
New Guinea Impatiens Flowering 23C 73F It takes about 11 weeks for first flower at 73F for a Stage 0 NGI
8
New Guinea Impatiens Flowering 23C 73F 20C 68F Decreasing temperature delays flowering
9
New Guinea Impatiens Flowering 23C 73F 20C 68F Stage 0.3 A reproductive cutting flowers earlier than a Stage 0 cutting
10
New Guinea Impatiens Flowering 23C 73F 20C 68F Stage 0.3 Stage 0.5 A reproductive cutting flowers earlier than a Stage 0 cutting
11
New Guinea Impatiens Flowering 23C 73F 20C 68F Stage 0.3 Variable cuttings yield variable flowering dates Stage 0.5
12
Without our Technique flowering will be un-uniform and it will be like picking tomatoes.
13
Optimized production of NGI in 4” pots Concepts: – Uniform flowering – Predictable flowering on date desired – Limited time (5 weeks) for plant in finish container
14
Recommended production schedule Recommended Liner size and age for 4 inch to 5 inch production is a 7 week old 50 cell liner with a low soil volume. Recommended Liner size and age of liner for Hanging Basket is a 4 week old 128 cell liner. The sooner you plant to finish container the larger the finished product will be.
15
Optimized production of NGI in 4” pots Small cuttings with small leaves helps control plants size in the Liner.
17
Large leaves create problems in propagation
18
New Guinea Impatiens with rot in Liner tray
19
Optimized production of NGI in 4” pots Small cuttings with small leaves help control plants size in the plug Flower buds in cuttings create production problems
20
New Guinea Impatiens plugs with flower buds
21
New Guinea Impatiens cuttings with flower buds at stick resulting in plants flowering before adequate vegetative size
22
New Guinea Impatiens cutting that was reproductive on arrival makes for a poorly branched plant
23
Small vegetative cuttings with small leaves eliminate these problems
24
New Guineas Liners looking super
25
Uniform vegetative cuttings, proper Liner production (nutrition and PGR) allows uniform and predictable flowering.
26
New Guineas starting to flower
27
Keys to 4” NGI production Appropriate genetics – moderate leaf size is best Stage 0 cutting Uniform small cutting Appropriate Liner soil volume Appropriate nutrition and PGR application Temperature control
28
Once a cutting initiates a flower, temperature is the primary factor driving time to flower, but relative humidity is also important because it affects plant temperature.
29
Other considerations Relative humidity at night is important. Low humidity will cause the plant to cool its self and will not realize the correct temperature. 80% humidity at night is best. Liner soil volume is important for plant size control
30
Both trays grown similar the one on the right has a higher soil volume
