One
of the most important environmental stresses is drought that great
effect on plant grow and metabolism. In this study, drought stress
effect on germination and inorganic elements content in leaves of
medical plant Purslane (Portulaca oleraceae
L.) were study. This plant as an Antiseptic, Antispasmodic, Diuretic,
and Blood Filtering has medical application. Drought stress imposed by
polyethylene glycol 6000 on seedlings and experiments in completely
random model framework and with 3 replications performed. Drought
levels imposed consist of Blank (distilled water), -0/1 -0/2 ,-0/4
,-0/6, -0/8 and -1 MPa. In relation with germination, observed that
with increasing of drought level, germination percent was decreased,
but this decrement was not meaningful in statistical level of 0/01,
which indication of high resistant Purslane than to drought stress in
germination stage. But in relation with inorganic elements in Purslane
leaves, meaningful increase of Sodium, and meaningful decrement of
Potassium, Calcium, Magnesium, Manganese, and Iron content with
increase of drought level, was observed (P>0/01). In relation to
sodium concentration, the highest content in level of -1 MPa and the
least concentration in blank level, was observed.The highest
concentration of potassium in -0/2 MPa and the least concentration in
-1 MPa, observed. Also, the highest and least concentration of calcium,
magnesium, manganese and iron observed in blank level and -1 MPa level,
orderly.
