Fusarium dry rot (FDR), caused by Fusarium species is an important potato disease world-wide and causes post-harvest rotting and seed-piece decay after planting. In this study, we compared two inoculation methods - cork borer wounding (CBW) and plastic screw wounding (PSW) - for consistent and reproducible disease development in potatoes Use the apple corer or cork borer to prepare at least three potato cores. Ideally, you prepare 9 cores, so you can do your experiments in triplicates. Push the corer or borer all the way through the potato and remove the core carefully so the potato piece stays intact Remove the potato cylinders from the cork borer & measure their length in centimeters. Cut the 3 potato cylinders to the same length (about 4 -5 centimeters long). Alternative: Peel off potato. Make slices of equal width (1/4in), and then use a potato dicer to make cores Using a cork borer, take four cores from a potato and use a knife to cut four potato cylinders about 3 cms. long. Caution: be very careful with the knife. Always cut away from yourself. Make sure there is no peel left on the cylinder. 4

Use a cork borer to cut 5 potato cylinders. 2. Trim the cylinders using a sharp knife and a ruler to the same length (about 3 cm). 3 1 A potato chipper will quickly cut chips of uniform size. It saves time if the chips are cut (using a chipper) just before or at the beginning of the lesson by a technician. Students still need to trim the chips to fit into the beaker/ boiling tube. If using a cork borer, each group (at least) should use a bores of the same diameter Flipped learning lesson on this osmosis lab HERE: http://sciencesauceonline.com/bio/osmosis-lab/Follow me on Instagram: https://www.instagram.com/sciencesauc.. 1.

Method. Use the cork borer to cut 11 potato samples, Cut each piece to 40 mm in length with no skin. Accurately record the mass of each piece of potato. Use the 1M sucrose solution to make up 11 solutions of different molarity, using the table below. Pour 10ml of each solution into a different test-tube. Molarity of the sucrose sol For example, a cork borer is used to maintain a constant surface area when testing the potato's water potential. A cork borer can also be used to punch holes on an agar plate and perform well diffusion assays to study bioactivity in microbiology. Let us observe the process of boring a Cork. Boring a Cork In this part of the lab, the student uses a cork borer to make 20 small cores of potato. The potato cores are massed 4 at a time to determine their initial mass. The 4 cores of potato are placed in solutions of different sucrose molarities. The first beaker contains distilled water, the second contains a .2M sucrose solution, the third contains.

A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing. Cork borers usually come in a set of nested sizes along with a solid pin for pushing the removed cork (or rubber) out of the borer. The individual borer is a hollow tube, tapered at the edge, generally with some kind of handle at the other end
