ANATOMICAL ADAPTIONS OF SUEDA SALSA (L.) PALL. (CHENOPODIACEAE) TO THE HARSH HALOPHYTIC HABITAT OF TECHIRGHIOL LAKE PUBLISHEDRodica Bercu
The article comprises the investigation of the root, stem and leaf anatomy of a species which frequently grows on the bank arround Thechirghiol Lacke near Constantza county, Sueda salsa (L.) Pall. The anatomical characteristics of Sueda salsa vegetative organs has been described and discussed. The mature root possesses a typical secondary structure. The stem has a primary structure surrounded by the cortex differentiated into a chlorencymatic and parenchymatic tissue. The stem vascular sysem, composed of xylem and phloem, forms a circular ring around the stem. Remarkable is the presence of the inner phloem due to the proliferation of the xylem vessels into the parenchymatous tissue. The stem and blade epidermis is covered by a thick cuticle supplimented by wax. It continuity is interruptured by the presence of paracytic stomata. The homogenous blade has no slat glands or salt bladders, thus, this plant must compartmentalize the toxic excess of Na + , K + şi Ca 2 in the leaf cells vacuoles, increassing the vacuoles concentration, withstanding to the harsh salting condition of its habit.
