lecture 6 Flashcards
1
Q
physiological seed dormancy
A
physiological mechanisms prevents radicle emergence
broken by temp/light changes
2
Q
physical seed dormancy
A
seed coat characteristics, impermeable by water
requires scarification or digestion
3
Q
morphological dormancy
A
under-developed embryo, finishes development after dispersion
4
Q
morphophysiological dormancy
A
morphological and physiological together
requires dormancy breaking treatment
5
Q
primary dormancy
A
under developed embryo - passes through this stage once
6
Q
secondary dormancy
A
physiological, occurs after non-dormant period
7
Q
persistent seedbank
A
seeds one or more years old - most common
8
Q
transient seedbank
A
no seeds viable for more than one year
