3. In this phase embryo in seed have stopped growing
It is the inability of a non dormant seed to germinate due to a lack of
suitable germinating conditions
This phase is triggered by the absence of favourable factors such as
light , temperature and moisture
The rate of cell division is suppressed
The embryo resume it growth under favorable condition
4. Importance
It is very important in the maintenance of stem cell population loss
of which can result in premature aging
It occurs in fast growing plants
Eg green leafy vegetables
It require relatively very short time
5. Quiescent centre are found in root meristem
It found mainly at the tips of growing roots in root meristem
It can be reversed upon the return of suitable conditions
6. Quiescent phase in cell division
Quiescent phase is the stage wherein cells remain
metabolically active but donot profilerate unless called to
do so
Such cells are used for replacing the cells lost during
injury
7. Similarities between dormancy
Both are delayed seed germination
Both prevent seed germination during the unfavorable
conditions
They increase the probability of seedling survival
Both are important for plant ecology and agriculture
