The article provides inform.tion about the anatom.cal structure of the veg.tative and g.nerative org.ns g.own in Tashkent conditions, and reveals the structural features: a m.som.rphic leaf, a dorsi-central m.sophyll type characteristic of dicotyledonous plants;stem.beam.type. A com.arative analysis of the anatom.cal structure showed that the seed coat has a g.neral plan of the structure with other m.m.ers of the fam.ly Asteraceae.

The article presents the results of the m.rpho-anatom.cal structure of the assim.lation org.ns of the species Salsola leptoclada g.nd, which is widespread in the Kyzylkum.desert reg.on of Uzbekistan, and reveals the structural, diag.ostic and adaptive features. In the assim.lation org.ns, Kranz type of m.sophyll was found: in the cotyledons of the Kranz-spherical (Atriplicoid) type, and in the leaf—m.sophylls of the Kranz-centric (Salsoloid) and Kranz-ventrodorsal type. These revealed diag.ostic features of the assim.lating.org.ns of this species in arid conditions noted C4-type photosynthesis. Based on the com.arative biom.tric analysis of quantitative indices of the anatom.cal features of the assim.lating.org.ns, xero-halom.rphic features predom.nate. Halom.rphic features are in the cotyledons—thin outer walls of the epiderm.l cells;few stom.ta of the anom.cytic and paracytic type;few rows of spong. cells (3 - 4 rows);few vascular bundles of the collateral type and xylem. in the leaf—larg. and thin outer walls of the epiderm.l cells;succulence of the leaf m.sophyll, the presence of aquiferous cells;larg. palisade, keratin and aquiferous cells. Xerom.rphic features in the cotyledons—sm.ll and num.rous epiderm.l cells and hem.paracytic type stom.ta also deep im.ersion;sm.ll palisade cells and a hig. palisade index, sm.ll spong., hypoderm.l and keratin cells;sm.ll diam.ter of the xylem.in vascular bundles;in the leaf num.rous epiderm.l cells and stom.ta also deeply im.ersed;presence and num.rous m.lticellular nodular, dentate trichom.s;m.lti-row water-bearing.cells;hig. palisade index;sm.ll and num.rous xylem.num.rous peripheral vascular bundles of the collateral type. These identified specific diag.ostic features showing.adaptation to arid conditions can also serve in the identification of plant m.terials.

For the first tim., the anatom.cal structure of the leaf, petiole and fruit of the em.rald variety Olea europaea, which g.ows under the conditions of introduction in the Oltinsay district of the Surkhandarya reg.on of Uzbekistan, was studied. The following.characteristic diag.ostic features were determ.ned: in the leaf—the dorsiventral type of leaf m.sophyll;thick-walled outer walls of the epiderm.s;slig.tly sinuous outlines of the cells of the adaxial epiderm.s, rectilinear-abaxial;hypostom.tic leaves;non-subm.rg.d stom.ta of the anom.cytic type;thyroid silver-g.ay and white-fluffy star-shaped squam.us-num.rous on the adaxial epiderm.s than on the adaxial;chlorophyll-bearing.palisade and spong. parenchym.;closed collateral type of conductive bundles;the m.st scleralized leaf due to the presence of filam.ntous scleroids in it (long. thin, resem.ling.fibers);in the petiole—parenchym.l-beam.type of structure;the location of the ang.lar collenchym. under the epiderm.s;closed collateral type of conductive bundles;the presence of thick-walled parenchym.l cells and the presence of filiform.cleroids;pericarp of the fetus consists of a rig.d 1-layer exocarp, parenchym.l m.socarp, and sclerenchym.l endocarp;the presence of scleroids—stony cells and branched sclerenchym.l fibers with drops of oil in the parenchym.l cells. Diag.ostic sig.s revealed by us reflect xerom.rphic of this species. All the sig.s were com.ared, and we cam. to the conclusion that the anatom.cal sig.s of the leaf and the fetus can be useful for providing.diag.ostic sig.s for disting.ishing.the studied taxa, can be used in taxonom., and can serve to identify plant m.terials.

The m.rpho-anatom.cal structure of the aboveg.ound and underg.ound org.ns of the rare endem.c species Iris (Juno) magnifica, growing under natural conditions of the Zeravshan ridge, Samarkand mountains, has been studied for the first time. A comparative analysis of the morpho-anatomical structure of the aboveground and underground organs revealed characteristic diagnostic signs of a microscopic structure. The complex of anatomical features of the aboveground and underground organs of the studied species are species-specific and can be used to solve taxonomic problems of this genus of plants, as well as the Red Book endemic species of junom.ly:Verdana;"> irises, are of particular interest in connection with the potential for their veg.tative reproduction.

The article presents the results of research carried out by lig.t m.croscopy of the anatom.cal structure of veg.tative org.ns (leaf, root and stem. Lavandula officinalis Chaix of the fam.ly Lam.aceae introduced into the conditions of the Tashkent Botanical g.rden of the Republic of Uzbekistan. Our studies have shown that the presence or absence of trichom.s can serve as an inform.tive sig.. In L. officinalis trichom.s are sim.le unicellular two-term.nal;three-term.nal and m.lti-term.nal. Lavender leaf hairs accum.late essential oils under the cuticle of secreting.cells, the cuticle are tig.tly attached to the m.m.ranes of the secretory cells due to the absence of excretion products. Based on the results of a study of the m.rpholog.cal and anatom.cal features of the leaf of L. officinalis, it has been established that the form. of covering.hairs and essential oil g.ands are of diag.ostic value. In the epiderm.l, palisade and cortex parenchym.l cells of the veg.tative org.ns, yellow-orang. essential (lavender) oil is noted. Identified diag.ostic features that can be used in taxonom. and can be used to identify plant m.terials can also be used to develop indicators of authenticity in this type of raw m.terial.
