Question

Seeds that desiccate and become quiescent are known as ________ seed while those that hydrated at the time of seed shed and are unable to withstand desiccation are known as ______________ seed. quilzewt

Answer 1

orthodox; unorthodox

Step-by-step explanation:

Orthodox seeds are the seeds which are long-lived and can be successfully dried to the moisture contents as low as 5% without the injury and are able to tolerate the freezing. They are therefore, also called as the desiccation tolerant seeds.

On the other hand, unorthodox seeds are short-lived and thus, cannot be dried to the moisture content which is below 20-30% without the injury and are also unable to tolerate the freezing. They are therefore, also called as desiccation sensitive seeds. The seeds are very difficult to be stored and also the ex-situ conservation of them is problematic.
