Question

More elongation of epicotyl than hypocotyl results in

Answer 1

Answer:

Hypocotyl elongation in Arabidopsis is the result of regulated cell expansion that is under both environmental and hormonal controls (2). In the absence of light, seedlings undergo skotomorphogenic development. The cotyledons remain closed, an apical hook is formed, and the hypocotyl becomes greatly elongated.

Answer 2

It is frequently used to study the growth promoting vs. growth repressing effects of application of plant hormones like ethylene. ... This rate is highest when plants are kept in darkness mediated by a process called skotomorphogenesis, which contrasts photomorphogenesis.
