At the early prophase stage of meiosis in microspore mother cells, five rows of cells were identified in Vitis vinifera L. Cv. Çavuş anthers consisting of a single layer epidermis in the anther wall surrounding the sporagenous tissue, one row of endothecium, one to two rows of middle layer and one row of tapetum layer. It was found that tapetum layer in anther cross sections comprises cells with lrgae nucleus and dense cytoplasm. It was observed that, during further development, epidermis was split into piece, tapetum cells developed abnormally and pollen mother cells grew up to larger sizes in some samples. Those cells were identified to consist of often two, occasionally one and rarely three to six nuclei. Moreover, differences were observed in nucleus size as well. It was reported that normal mitosis division and sticky division in tapetum cells occurred at the same time.

The Programme for Conservation of Plant Genetic Resources in the Republic of Srpska was established in 2008. The main objective of the Programme is effective management of plant genetic resources through carrying out of continuous field inventories and collection, evaluation, exchange and conservation of germplasm. The Genetic Resources Institute, University of Banja Luka was appointed as a expert unit for coordination and implementation of the Programme. In the period from 2009 to 2011, the inventory was made for part of the area of the Republic of Srpska. An innovative approach was adopted for conservation of plant genetic resources by means of long-term seed preservation, in vitro conservation, morphological and molecular characterisation, as well as regular database updates. Contacts were established with producers for the purpose of on farm protection of local ecotypes and populations. An ex situ collection was established in the Botanic Garden for plant species that can not be conserved in the form of seeds. By the end of 2011, the Gene Bank had reached its full operation with 455 accessions in long-term storage (-18 o C), around 150 accessions in the working collection and 100 accessions in the field collection. With its 91 accessions, the Genetic Resources Institute is part of a European web-based catalogue of inventories of plant genetic resources (EURISCO). Having adopted the Programme, the Republic of Srpska has not only fulfilled one of the world's peremptory obligations to conserve biodiversity of agricultural crops, but also a moral obligation to future generations.

2 Federalna uprava za inspekcijske poslove, Sarajevo, BiH SažetakSkoro celokupna proizvodnja grožđa u BiH, realizuje se na području Hercegovine, gde se već duži niz godina zadržava odnos od približno 80% površina pod vinskim i 20% površina pod stonim grožđem. Autohtone vinske sorte Žilavka i Blatina imaju najveći značaj u vinogradarskoj proizvodnji u ovoj regiji, zbog čega su predmet mnogobrojnih istraživanja i analiza. U ovom radu su prikazane najvažnije ampelometrijske karakteristike grozda sorti Žilavka i Blatina. Deo eksperimentalnih istraživanja u cilju ampelometrijskih analiza karakteristika grozda, bobice i semenke, realizovan je u proizvodnom vinogradu Aluminijskog kombinata u Mostaru. Imajući u vidu da je funkcionalna morfologija cvasti i cveta vinove loze u reproduktivnoj biologiji, veoma važan faktor efektivnosti reproduktivnih organa u funkciji realizacije visokih prinosa odgovarajućeg kvaliteta grožđa, posebna pažnja u ampelografskom proučavanju sorti Žilavka i Blatina, posvećena je karakteristikama na koje direktan uticaj ima stepen oplodnje: grozd, bobica i semenka. Istraživanja su realizovana u periodu 2009-2011. godina. Prosečna masa grozda sorte Blatina za period istraživanja iznosila je 228,28 g i kretala se u rasponu od 169,35 g do 289,19 g, sa prosečno 65,80 bobica u grozdu. Prosečna masa bobica sorte Blatina, iznosila je 3,49g, sa prosečno 1,51 semenkom u bobici. Prosečna masa grozda sorte Žilavka za period istraživanja iznosila je 223,16 g i kretala se u rasponu od 170,06 g do 325,45 g, sa prosečno 114,47 bobica u grozdu.
