樹木植物防疫快篩組

大家作好防疫與隔離了嗎? 希望大家作好隔離，這是目前最有效法方法。

作物在田間很難作隔離，樹木也不太可能做到(你很難去移動它們)，因此早期發現是非常重要的工作，PocketDIAGNOSTIC 公司出了疫病快篩組，可以快速檢測 Phytophthora 、Potato virus、Ralstonia solanacearum。

1. Select a sample (as detailed below)

2. Cut or tear sample into small pieces and put into bottle containing buffer and ball bearings

3. Shake firmly for 30-60 seconds to break up the sample and allow the liquid to settle

4. Draw liquid into the pipette – avoid sample debris and air bubbles

5. Keeping the test device level, add 2 drops into the sample well of the device

6. Valid results within 10 minutes

How To Test Wood Samples

• Select a sample using a fine blade. Remove the outer bark or external root covering to reveal the soft bark. Samples need to include both the leading edge* and a small area just in front of this (*the area where the diseased part of the plant meets the healthy part of the plant). Note: the test does not work directly on ooze from the cankers.

• Samples must be broken down prior to placing in the extraction bottle. This is best done by finely slicing and crushing.

• Add the sample to the extraction buffer and secure the lid tightly.

• Shake the bottle vigorously for 60 seconds.

• Allow the plant debris to settle to the bottom and then draw up the extraction liquid into the pipette. Add 2-3 drops into the sample well avoiding adding any air bubbles or debris.

• Valid results appear within 10 minutes. Do not count any results after 10 minutes. One line is a negative result and two lines is a positive result.

Always read the instructions before using Pocket Diagnostic® rapid tests.

Phyllotactic patterning of gerbera flower heads

(corresponding to Fig. 7). Simulation of the patterning of bract and floret primordia on an expanding disk. The simulation is effected using Model 2 (the disk model), overlaid on the composite images of heads up to the 34-primordium stage. The decreasing radius of the circles that represent primordia reflects the decreasing threshold distance for the insertion of new primordia according to the Hofmeister / Snow & Snow rule. The model captures the differences in the radial position of primordia that become visible at the 21-primordium stage and are pronounced at the 34-primordium stage, as highlighted by the simulation pause. The continuing simulation captures the emergence of parastichies based on the template of bracts and the patterning of florets, which stops when the entire receptacle surface is consumed.

corresponding to Fig. 9E). A variant of phyllotactic patterning in gerbera heads (Movie 5). The active ring becomes transiently elliptic during the patterning of florets. In spite of the loss of circular symmetry leading to the occurrence of some dislocations (local departures from the mathematically ideal spiral phyllotaxis), the final pattern closely resembles that produced with the circular active ring.

Model validation. (A and B) Comparison of predicted and observed positions of DR5 maxima in the early patterning phase. (C–F) Comparison of predicted and observed intermediate patterning stages with circular (C and D) and elliptic (E and F) pattern fronts. Chl, chlorophyll. (G and H) Comparison of predicted (G) and observed (H) positions of the first 21 bracts on the lower side of a gerbera head. (I and J) Comparison of predicted (I) and measured (J) distances of bracts from the stem center. For the measured distances, mean values in a set of 12 heads (horizontal lines) and the standard errors (vertical bars) are shown. (K and L) Comparison of the simulated head (K) with the SEM of a real head (L). [Scale bars: 5 mm (H); 1 mm (L).]
