AB  - The analysis of participation of harmful and undesirable species in the floristic composition of hilly meadow communities, such as ass. Agrostietum vulgaris Pavl. 1955, ass. Koelerietum montartele Pavl. 1951. and ass. Poo alpinae-Plantaginetum holostei Pavl. 1951 spread on the Stara planina mountain was carried out in order to estimate the quality and, thus the perspectives for utilization and management of these grasslands. The presence of weed species in investigated phytocoenoses ranged from 36.73% to even 67.24 % in ass. Poo alpinae-Plantaginetum holostei and ass. Koelerietum montanae, respectively, indicating the long-term exposure of these meadows to a man-made and grazing pressure. Among the poisonous species, the most frequent were Veratrum album, Colchicum autumnale and Euphorbia cyparissias. In the biological spectrum of analyzed grasslands prevailed the hemicryptophytes, and in the less extend the chamephytes, which might be related to their unsustainable utilization. Therefore, it could be recommended the application of the adequate management practices, including fertilization, to improve the quality of these communities and preserve biodiversity and the natural resources for further exploitation.

AB  - Selection program to produce closely related genotypes varying in the leaf content of plant hormone abscisic acid (ABA) was done with maize to test morpho-physiological consequences of this genetic modification. The cross was done between two maize lines Polj-17 and F-2 that have previously been shown to differ by up to three-fold in leaf abscisic acid concentration in the field. The progeny was classified into high ABA (H) and low ABA (L) lines according to leaf ABA contents of individual plants in the F4 generation. The lines were studied in the field with the aim to characterize the differences amongst the lines in some morpho-physiological traits (leaf ABA and xylem ABA contents, stomatal conductance, water potential, plant height and leaf number) and yield. Data analysis done by ANOVA program has shown statistically significant differences between two classes of lines in leaf and xylem ABA contents, plant height and number of leaves. Obtained results also showed that high-ABA lines out yielded low-ABA lines. Differences between the ABA lines in both, leaf ABA content and xylem ABA content were unlikely to be due to differences in leaf water status. Therefore, other possible explanations for the genotypic differences and their consequences on yield are discussed.
AB  - Selekcioni program u kome su obrazovani genotipovi koji se razlikuju u sadržaju biljnog hormona abscisinske kiseline (ABA) u listovima je urađen sa ciljem da se testiraju morfo-fiziološke posledice te genetske manipulacije. Ukrštanje je izvršeno između dve linije kukuruza Polj-17 i F-2 za koje su prethodna ispitivanja pokazala da se razlikuju vise od tri puta u koncentraciji ABA u poljskim uslovima. Na osnovu sadržaja ABA u listovima pojedinačnih biljaka, potomstvo je podeljeno u dve klase i to na linije koje su visoki (H) i niski (L) akumulatori abscisinske kiseline u listovima. Linije su ispitivane u poljskim uslovima sa ciljem da se karakterišu razlike između njih u nekim morfo-fiziološkim osobinama (sadržaj ABA u listovima i ksilemu, provodljivost stoma, potencijal vode, visina biljaka i broj listova) i prinos. Analiza podataka je urađena uz pomoć ANOVA programa i ona je pokazala statistički značajne razlike između dve klase linija i to u količini ABA u listovima i ksilemu, visini biljaka i broju listova. Dobijeni rezultati takođe, pokazali su da su linije visoki akumulatori ABA imale veći prinos od linija niskih akumulatora. Razlike između ABA linija u sadržaju ABA i u listovima i u ksilemu nisu bile rezultat razlika u vodnom režimu biljaka. Stoga su diskutovana draga moguća objašnjenja ovih genotipskih razlika i njihovih posledica na prinos.
