The seeds were scarified using sandpaper and then germinated in a petridish until the radical was approximately 5 mm long. They were then planted in the growth chambers alternating diploid and tetraploid. Over a 6 week period the plants were observed and measured. This graph shows the average seed size of the four varieties studied. This graph shows total number of leaflets versus time.
Leaflet number is a good indicator of overall plant size.
The diploid variety from the Russian Federation, which had the second largest seed has the second highest number of leaflets. This graph shows the log of the overall root growth rate. There are no significant differences between the varieties here. Most likely due to limitations of our growth chambers. We would like to modify the design of the chambers to be deeper to facilitate more accurate measurement of root growth rate.
