Albino Tobacco Seeds
Easy to germinate and easy to grow. These classic genetic seeds display a Mendelian 3:1 ratio. Germinate them in Petri dishes and compare the phenotypic results in
the light versus the dark. Can the genetics be altered? Reversing the seed locations will provide an answer for students. Approximately 800–1,000 seeds in 0.1-g sample.

How to Germinate Seeds
There are several things you can do to ensure seed germination and growth.
An all-purpose potting mix (such as Jiffy Mix®) or milled sphagnum moss make excellent germination media. The starter medium should be placed in seed trays or small pots to a depth of two to three inches. Some seeds can be soaked for 12 to 24 hours prior to planting to speed germination. An easy way to do this is to wrap the seeds in a moistened paper towel.
Most seeds should be sown at a depth of up to three times their diameter. Small seeds can be scattered over the soil and lightly pressed down. Water the seeds by gently sprinkling with warm water. Cold water could lower the temperature
of the soil below the germination level. Always keep the soil moist. Cover the seeds with a pane of glass or plastic wrap to trap heat and conserve moisture. Try to keep the seeds at 22 to 27 °C. After the seeds have germinated, remove the glass and use fluorescent lights to warm the seedlings. At this point it is a good idea to thin out the seedlings—leaving only the largest and strongest. As soon
as the seedlings can be handled, transplant them to larger containers, leaving enough room for each plant to grow unrestricted. Water regularly. Dilute (half- strength) fertilizer may be applied three to four weeks following germination.
