Question

are annual rings formed in the root of temperate plants?give reasons

Answer 1

Yes, annual rings are formed in the root of temperate plants like forbs (A broad-leaved, flowering herb other than a grass) with persistent main roots. The growth rings are associated with full growing seasons and the development of the anatomical patterns is consistently seasonal. It results from the formation of earlywood vessels with large lumen in spring and latewood vessels with smaller lumen in late summer and autumn. Counting the number of annual rings in the roots of forbs has
been used for age determination and demographic analyses.
