Potres u Crnoj Gori 1979. i posljedice za muzejsku mrežu

Katastrofalni potres koji je 15. travnja 1979. godine pogodio Crnu Goru prouzročio je velika razaranja u gradovima i naseljima na jadranskoj obali i u neposrednom zaleđu. Najveća oštećenja pretrpjeli su stari gradovi na obali u kojima se nalazio najveći broj zaštićenih nepokretnih spomenika kulture. Muzeji u Crnoj Gori, osnovani uglavnom početkom 20. stoljeća i nakon Drugoga svjetskog rata, smješteni su u adaptiranim zgradama sagrađenim u ranijim razdobljima koje nisu imale odgovarajuću konstruktivnu zaštitu. Sve muzejske zgrade pretrpjele su znatna oštećenja, kao i muzejski predmeti koji su bili izloženi ili pohranjeni. Nakon prvih popisa i izvještaja utvrđeno je da su oštećena ili uništena 1642 nepokretna kulturna dobra i više od 33 tisuće pokretnih kulturnih dobara. Nakon inventariziranja, privremenog smještaja i privremene zaštite nepokretnih i pokretnih spomenika kulture pristupilo se sanaciji i obnovi oštećenih objekata te konzervaciji i restauraciji pokretne kulturne baštine. U tijeku obnove oštećenih objekata primjenjuju se suvremeni standardi aseizmičke gradnje

Investigation of pollen morphological characteristics in some quince (Cydonia oblonga Mill.) cultivars

Morphological characterization of pollen grains is very important in the identification of individual species and cultivars of fruit trees, including quince. As material for these studies, the pollen of eight quince cultivars, Leskovacka, Vranjska, Morava, Pazardzijska, Hemus, Asenica, Portugal, and Triumph was used. During the 3-year study period (2010-2012), using scanning electron microscopy (SEM), the following characteristics were investigated: the size and shape of pollen grains (length, width, and length-to-width ratio), colpus length, colpus width, mesocolpium width, and characteristics of exine pattern [number of ridges per area (100 mu m(2)) at the equatorial region of exine, ridge width, and furrow width]. The tested quince cultivars differed significantly in terms of morphological characteristics of pollen. The exceptions were colpus and mesocolpium width, as well as the ridge and furrow width on the exine, which showed no statistically significant difference. Pollen grains of quince are characterized by great length (over 53 mu m). The shape of pollen grains varied from prolate (Leskovacka, Vranjska, Morava, Hemus, Asenica, and Triumph) to perprolate (Pazardzijska and Portugal). The exine pattern of all cultivars was striate with longitudinal ridges, which were more parallel in cultivars Vranjska, Hemus, Portugal, and Triumph and less parallel in cultivars Leskovacka, Morava, Pazardzijska, and Asenica. Three groups of similar cultivars are separated on the basis of hierarchical cluster analysis results. Some pollen morphological characteristics, such as the size and shape of pollen grains and colpus length, can be used in the identification of quince cultivars

Influence of temperature on pollen germination and pollen tube growth of plum cultivars

The temperature is an important environmental factor that affects pollen performance during the reproductive phase of fruit tree species. Pollen germination is one of the main factors for successful fertilization and fruit set in plum (Prunus domestica L.). The study was carried out to determine the effect of three different temperatures (5, 15 and 25°C) on the pollen germination and pollen tube growth in vitro of six European plum cultivars: ‘Cacanska Lepotica’, ‘Cacanska Rana’, ‘Jojo’, ‘Top’, ‘Toper’ and ‘Stanley’. Germination rate and pollen tube growth were determined on a culture medium containing 15% sucrose and 0.7% agar. Temperature significantly affected pollen germination of all studied cultivars. High germination rates (50‒76%) were obtained at the temperatures of 15°C and 25°C. However, satisfactory germination rates (29‒47%) were also obtained at the temperature of 5°C in some cultivars (‘Toper’, ‘Cacanska Rana’, ‘Cacanska Lepotica’ and ‘Top’). The influence of temperature was more prominent on the pollen tube growth. The length of pollen tubes was six to twelve times higher at 15°C and 25°C in comparison with 5°C. This has led to the conclusion that the temperature of 5°C, although it could be enough for pollen germination, is not enough for optimal pollen tube growth

Fenotipska varijabilnost osobina plodnosti čistorasnih krmača u prva tri prašenja

Investigation of the phenotypic variability of fertility traits was performed on Swedish Landrace sows (926 sows) deriving from single herd in Serbia. Data was processed by method of least squares (Harvey, 1990), and following fixed factors were included into the model: sire, season, litter genotype and order of farrowing, as well as regression effect of age at first farrowing, duration of lactation and number of reared (raised) piglets per litter. Traits of litter size varied (P lt 0.01) under the influence of sire and order of parities (first two parities). Number of still born as well as reared piglets per litter depended on the litter genotype (P lt 0.01). Year and season had no effect on variation of litter size traits except LWW (first two and three parities). Age of sows at first farrowing demonstrated linear effect (P lt 0.01) on size of their litter at farrowing (first three parities). Litter size and weight at weaning were under regression effect of lactation duration as well as corrected litter size (CLS) or number of weaned piglets (NW).Ispitivanje fenotipske varijabilnosti osobina plodnosti krmača rase švedski landras sprovedeno je u jednom zapatu svinja u Srbiji. Podaci su analizirani primenom različitih modela metoda najmanjih kvadrata (Harvey, 1990), u koje su bili uključeni sledeći fiksni uticaji: otac, godina, sezona, genotip legla i redosled prašenja, kao i regresijski uticaji uzrasta pri prvom prašenju, trajanja laktacije i broja gajene prasadi u leglu. Istraživanjem je bilo obuhvaćeno 926 krmača i njihova 926 prva, 1598 prva dva i 2115 prva tri prašenja. Prosečna ispoljenost trajanja perioda od zalučenja do estrusa i oplodnje (W-E i W-C), broja živorođene (NBA), ukupnorođene (TNB), mrtvoroĐene (NSB) i odgajene prasadi (NW) kao i mase legla pri zalučenju (LWW) u prvom, prva dva i prva tri prašenja je bila: 9.77, 8.51, 7.80; 23.77, 20.98, 19.49; 8.31, 8.91, 9.19; 8.87, 9.46, 9.78; 0.56, 0.54, 0.51; 7.57, 8.04, 8.24 i 52.43, 58.18, 61.10, respektivno. Osobine veličine legla su varirale (P lt 0.01) pod uticajem oca i redosleda prašenja (prva dva prašenja). Broj mrtvorođene kao i odgajene prasadi u leglu zavisili su od genotipa legla (P lt 0.01). Godina i sezona nisu uticale na variranje osobina veličine legla osim na LWW (prva dva i tri prašenja). Uzrast krmača pri prvom prašenju ispoljio je linearan uticaj (P lt 0.01) na veličinu njihovih legala pri prašenju (prva tri prašenja). Veličina i masa legla pri zaluženju su bili pod regresijskim uticajem trajanja laktacije, korigovane veličine legla (CLS) ili broja odgajene prasadi (NW)

Fiksni deo modela za procenu priplodne vrednosti svinja na osnovu veličine legla

The goal of this paper was to investigate the effect of various fixed effects on the number of born alive piglets in litter (NBA), based on results of Swedish Landrace sow fertility on three farms in Serbia, in order to determine the best adapted model for assessing genetic parameters and breeding value. Analysis of phenotipic variability of the NBA of Swedish Landrace sows was carried out based on fertility results on three swine farms (A, B and C) in the Republic of Serbia. Data sets encompassed reproduction indicators for 2803 (A), 1826 (B) and 2235 (C) sows, i.e. their 11014, 6757 and 8452 litters, respectively. For this analysis was used fix model of least square method which includes fixed effects of farrowing number, season of conception shown as combination of year and month, litter genotype, duration of previous period from weaning to conception, effect of sow age at farrowing like quadratic regression nested within farrowing number and linear regression influence of duration of previous lactation. The average NBA was within the interval from 9.13 (A) to 9.76 piglets (B and C). The monitored trait statistically highly significantly (p lt 0.001) varied under the effect of all systematic factors encompassed by the applied model, regardless of the source of analyzed data, Only the linear regression effect of duration of previous lactation for farm B was assessed as having lower statistical significance (p lt 0.05).Cilj ovoga rada bio je da se ispita uticaj različitih sistematskih faktora na variranje broja živorođene prasadi u leglu (BŽP) radi određivanja najprilagođenijeg modela za ocenu genetskih parametara i procenu priplodne vrednosti krmača. Analiza fenotipske varijabilnosti BŽP u leglima krmača rase švedski landras sprovedena je na osnovu reproduktivnih pokazatelja 2803 (farma A), 1826 (farma B) i 2235 (farma C) krmača, odnosno njihovih 11014, 6757 i 8452 legala, respektivno. Korišćen je fiksni model metoda najmanjih kvadrata u koga su bili uključeni uticaj prašenja po redu, sezone uspešnog pripusta, genotipa legla, trajanja perioda zalučenje - oplodnja, kvadratni regresijski uticaj starosti krmače pri prašenju ugnježđen u okviru prašenja po redu i linearni regresijski uticaj trajanja prethodne laktacije. Prosečan BŽP se kretao u intervalu od 9.13 (A) do 9.76 (B i C). Svi determinisani uticaji obuhvaćeni modelom su ispoljili statistički vrlo visoko značajan uticaj (p lt 0.001) na variranje BŽP nezavisno od toga koji set podataka je bio analiziran, osim uticaja trajanja prethodne laktacije na farmi B koji je bio ocenjen kao statistički značajan (p lt 0.05)

Uticaj obima analiziranih podataka na tačnost selekcijskih indeksa za procenu priplodne vrednosti krmača

Objective of this paper was to establish to what extent the accuracy of constructed selection indices will be changed depending on the scope of analyzed data relating to fertility based on which parameters necessary for construction of selection indices (SI) were established. Fertility results of Swedish Landrace sows obtained on three farms in Republic of Serbia (farms 1, 2 and 3) were analyzed. Parameters necessary for construction of SI were determined by application of different mixed models of the method of Least Squares. For each farm three SI were constructed for evaluation of sow breeding value based on realized fertility in the way that parameters necessary for SI construction were calculated based on fertility results in the first (SI1), first two (SI2) and first three farrowings (SI3). Accuracy of constructed Sis varied within following limits - from low rIH = 0.255 (SI3 for Farm 2) to rIH = 0.405 (SI1 for Farm 3), and only in the case of SI2 for Farm 2 it was in the category of very low (rIH = 0.231). Introduction into analysis of fertility results realized in the second and third farrowing resulted in decrease of accuracy of constructed selection indices.U ovom radu rezultati istraživanja su pokazali da je tačnost selekcijskih indeksa konstruisanih na osnovu parametara ocenjenih analizom rezultata plodnosti (BŽP i BOP) ostvarenih na posmatranim farmama bila od rIH = 0.255 (SI3 za Farmu 2) do rIH = 0.405 (SI1 za Farmu 3), a samo je u slučaju SI2 za Farmu 2 bila u kategoriji jako slabe (rIH = 0.231). Povećanje obima analiziranih rezultata plodnosti dovelo je do smanjenja tačnosti SI
