Radishes provide a cheap and reliable way to carry out a number of investigations into plants, including nutrient requirements, effects of growing conditions, etc. This protocol outlines a simple method of growing radishes that can be used in the school lab.

Investigating Vernalisation & Creating Genetic Crosses

Certain plants require a cold spell in their life cycle to initiate the sequence of events that leads to flowering – known as vernalisation. This sheet describes the process of vernalisation and how it can be done to help induce flowering in Chinese cabbages. You can then use the resultant plants to carry out genetic crosses.
