The master thesis contains anatomical – morphological description of axial parts, normally steams, rhizomsteams and leaves, of Lunaria rediviva L., Lunaria annua L. All investigated parts contains (heterobathmy). Steams and rhizomsteams contain glands of shizogenical origin, but roots do not have it. Impact of vegetation conditions to anatomical – morphological texture of mezohygrophites was investigated. In creah (humid habital) hygromorphical characteristics were revealed: - more space among the cells were found and the were bigger; - less amount of supporting tissues; - wolls of the were less warred; - relatively less atomata in a measurement. In a terrace (dry habital) kseromorphical characteristics were revealed: - cells of the supporting tissues were more solid and there bigger quantity of them; - epidermal cells were smaller but wolls the cells were more warred; - the type stoma apparatus and amount of stomata in a measurement. Circulating tissues in steams of Lunaria rediviva were changing are arranged in fascicular type, in rhizomesteams in non – fascicular type. Size of circulating tissues varies depending on habital. Medulles rays are heteroghenical, composed by 2 – 5 cells rows.

Visa gyvybė priklauso nuo augalų gebėjimo sugerti saulės šviesos energiją ir paversti ją cheminių medžiagų energija, kurią naudodamas augalas palaiko savo gyvybinius procesus, auga ir dauginasi. Augaline medžiaga maitinasi žolėdžiai gyvūnai, sudarantys bet kurios mitybos grandinės pagrindą, vadinasi, augalų gebėjimas panaudoti saulės energiją palaiko beveik visą gyvybę žemėje. Augalai yra svarbiausi palaikant žemės atmosferos kokybę (Marinelli ir kt., 2006). Darbo tikslas – nustatyti trilapės blignos (Isopyrum thalictroides), daugiametės blizgės (Lunaria rediviva L.), meškinio česnako (Allium ursinum) paplitimą Lyduvėnų kraštovaizdžio draustinyje ir įvertinti retųjų augalų buveinių valdymo principus. Darbo metodai – lauko darbų metu registruoti retieji augalai, augantys Lyduvėnų kraštovaizdžio draustinyje. Maršrutiniu metodu buvo vizualiai stebėti retieji augalai, augantys draustinyje. Augalų būklė įvertinta pagal augalų populiacijos skaičių, gyvybingumą, fiziologinę būseną ir augimo sąlygas. 2014 m. augalų kiekio pokyčiai nustatyti pagal Braun-blanqe metodiką. Gauti duomenys išanalizuoti ir palyginti su ankstesnių tyrimų duomenimis. Darbo rezultatai. Tyrimų metu nustatyta, jog 2014 m. trilapės blignos (Isopyrum thalictroides) ir meškinio česnako (Allium ursinum) gausumas lyginant su ankstesnių metų duomenimis yra padidėjęs. Daugiametės blizgės (Lunaria rediviva L.) augalų...

The plants use this energy for maintenance of there one vital development, for growth and for propagation. The herbivores feed on plants, they are the basis of any food web. It means, that the plants ability to imbibe the heat of the sun’s rays keep holding almost the whole life on the earth. The producers (plants) are the most important species, which maintains the quality of earth atmosphere. (Marinelli and oth., 2006). Work goal is to ascertain the spreading Isopyrum thalictroides, Lunaria redivida and allium ursinum on the area of Lyduvenai reservation and to appraise the handling principle of thinly growing plants. Work methods. During the work on fields the registration of thinly growing plants on the Lyduvenai reservation. Visual observation was used on shuttle method. The plants status was appraised at number of plants population, vitality, physical state and the growing conditions. Change of plants state was established according to the population, tendency to increase and decrease in population. The obtained data was analyzed and compared with the data of previous research. Work results. During the research was ascertained the condition of all three investigative plants Isopyrum thalictroides, Lunaria redivida and allium ursinum. The condition in comparison with previous research has not... [to full text]
