2011 Jubilee — 1139 Natural Days

Growth Regulators Applied / Height graph

Graph shows projected plant heights during production of the crop. Dots are plotted actual height each week. Arrows indicate when PGRs are applied with details in the weekly notes. We use the “late” graphical tracking curve and heights are from bench to height of growing tip. Heights are plotted from date of pinching to projected date of finish.

2011 growth chart for Jubilee - 1139 Natural Days poinsettia


Jubilee 1139 Natural Days 11-2211/22

This crop of Jubilee on natural days looks good and has finished on schedule. This is a new variety with significant potential in warm climates. It has a stronger plant habit and branch structure than Freedom Red and timing is similar to Freedom. From this crop, the delayed example here and our research crops, we have learned more about this variety. Notice that in late Oct. and early Nov. these plants were slowing down. However, in the past 2 weeks we have had higher day temperatures and the plants responded with additional elongation. Jubilee does have potential for strong growth as the bracts are developing, so it is important to be ready to manage that, especially in high temperature situations.

Jubilee 1139 Natural Days 11-1511/15

These plants continue to look good. We got a little more growth this week with a few warmer days. Pollen is showing on about 10% of the crop and the crop will finish on schedule.

Jubilee 1139 Natural Days 11-811/8

This crop of Jubilee is continuing to do fine. With the mild temperatures it probably will not elongate much in next couple of weeks and likely will finish at about 15". We are getting good bract expansion on these plants.

Jubilee 1139 Natural Days 11-111/1

This crop of Jubilee continues to look good and should finish on schedule. The 0.1 ppm drench applied 3 weeks ago should have only a small effect on the plants now, so we will see where the plants are next week when we may apply a late drench. We would drench this week if we wanted to make sure the plants stayed under 16".

Jubilee 1139 Natural Days 10-2510/25

These Jubilee look good. We anticipate they will continue growing at this rate for another couple of weeks. Visible bud is starting now and the crop appears to be on time.

Jubilee 1139 Natural Days 10-1810/18

These Jubilee responded to last week PGR more than anticipated. However, shoot tips are not too tight so the plants should not stall out. The first hint of color is showing on a few plants, which indicates they should be on schedule.

Jubilee 1139 Natural Days 10-1110/11

These Jubilee got off to a slow start and we have not applied any PGR. This past week they grew almost 2" and the shoot tips indicate they will continue rapid elongation. So, to slow them down we are applying a Bonzi drench at 0.1 ppm. They are growing so fast they may still do 1.5" this next week.

Jubilee 1139 Natural Days 10-410/4

With our cooler weather now, we want to see how this crop grows before we apply a PGR. We still anticipate needing to do 1 or 2 applications.

Jubilee 1139 Natural Days 9-279/27

This group of Jubilee is just starting to grow and we will see how they do this next week. We do not think heat delay is an issue with this variety and it should be initiating now.

Jubilee 1139 Natural Days 9-209/20

This is another crop that is doing better now. PGRs are not needed this week.

Jubilee 1139 Natural Days 9-139/13

This crop is another that is growing at a slow pace and we expect it to start elongating faster with our more normal temperatures.

Jubilee 1139 Natural Days 9-69/6

These plants look good at this stage and we will see where they are next week.

Jubilee 1139 Natural Days 8-308/30

Jubilee is a new variety that has performed well in our research trials. It has strong stems, but is not too vigorous. Based on last year's experience it should not be too difficult to control.
