2.6. Plant harvesting
After 60 days of plant growth, shoots from PT1, and shoots and
roots from PT2 were harvested. The shoots were cut ∼0.5 cm above
the
soil surface and the roots removed from the soil with tweezers.
Shoots and roots were oven dried for 5 days (60 ◦ C) and shoots thenweighed for dry mass. Once dried, soil was removed from PT2 roots
using tweezers and a fine brush.
