Root and shoot production in non‐transformed wildtype (60444) and the four independent transformants at harvest.

<p>(a) Storage-root dry weight; (b) total plant dry weight; (c) harvest index (HI), calculated as HI = (storage-root dry mass)/ [(storage-root dry mass) + (above-ground dry mass)]; (d) number of storage-roots. Shown are the means ± SEM.
