of all cultivars reached the Al-toxic bottom layer 3 d after planting.
Correlation coefficients between fall dormancy and the five root traits showed that dormant PIs tended to have greater fibrous root mass, more lateral roots and smaller taproots
than less dormant Pis (Table 3).
All plants along 2 m of row were harvested (including taproots
from the first 20 cm of soil) and then sorted according to taproot
Cunningham and Volenec (1996) recently described three polypeptides present in alfalfa taproots
that are extensively degraded after defoliation and in spring when shoot growth resumes.
solani could not be recovered from surface sterilized taproots
suggesting infection had not yet taken place.
Walnuts have deep taproots
and prefer a deep, well-drained soil in full sun.
were rubbery and the epithelial layer was gone or not secured to the root.
Figure 4-2 shows the three basic types of root systems: taproots
, which have a main central root, and a storage taproot
, which acts as a food reservoir to retain surplus food during the winter or adverse periods, fibrous roots, which have many roots of equal size.
Keep on top of weeds, especially those with deep taproots
such as dandelions, which suck up precious moisture.
Some QTLs were associated with both basal and taproots
, and others only with one or the other, while some QTLs for these traits were associated with specific RL and others were not.
This will encourage the plant to send strong taproots
looking for moisture.
