Appendix A

Pollen for determination of a single species of bee pollen A.1 Instruments A.1.1 microscope. 10 to 100 times. A.1.2 centrifuge. speed 10000r/min. A.2 Reagents A.2.1 sulfuric acid and glacial acetic acid (volume ratio of 1.9). A.2.2 glycerol (AR). A.3 sample handling Bee pollen 1g ~ 2g take place 15mL graduated centrifuge tube, adding sulfuric acid and glacial acetic acid (1.9) a mixture of 2mL, pollen immersion grain. Mashed with a glass rod pollen, boiling water bath for 5min. Cooling, distilled water volume to 10mL. Centrifugation, the supernatant was discarded, washed repeatedly by centrifugation Step 3 times. Glycerol was added dropwise number precipitate mix. 1 with a glass rod dipped drop coated onto a glass slide, covered with a coverslip. A.4 count Take already processed slides were observed under the microscope at 10x or 40x objective. The smear found pollen grains too dense resulting in overlap When Count of, should be re-smears, the number of pollen grains per field preferably in the range of 30 ~ 100. Select 5 visual field of view and All counts pollen grains in the field, and with different authentication control map pollen species. The number of particles of a variety of pollen 5 Perspective view with 5 All wild than the total number of pollen grains of pollen rate is the single species of bee pollen. Each test should be carried out parallel tests. A.5 bee pollen (pollen single species of pollen hetero) Identification A.5.1 rapeseed (Brassicacampestris) pollen Canola flower pink yellow.
