ملائمة النباتات للنباتات الجافة

الملخص EN

Due to the harsh conditions of dry regions plants , these plants must be adapted to these conditions.

In order to live in these regions, one must realize two facts, scarcity of water resources and severe evaporation factors.

Thus plants must increase water saturation and lessen evaporation.

Thus dry plants features fall into one of the following categories: either increase saturation or decrease evaporation or both, so that plant can keep aqua balance to continue existence.

Failure to any of these conditions (i.e.lack of suckling or increase evaporation ) will cause withering and then death.

Continuity of green plants in dry environments is a proof of its ability to keep such balance.

It is however not to prejudice that all plants of dry environments can keep this balance, more likely evaporation may, at some time of the day, increase .

But these plants with its organic characters and anatomic features regain its aqua balance for a short period.

This period though is much more longer to be tolerated by plants that grow in normal environments.
