[Method] With the mRNA from different tissues as template, RT-PCR amplification was carried out for cloning cDNA of hybrid pig, which was then used for PCR reaction using specific primers; the amplification products were separated by gel electrophoresis and analyzed by sequencing for detecting the distribution pattern of H-FABP mRNA in hybrids of Songliao black pig x Sus scrofa. [ Result] H-FABP expressed in all the twelve tissues including subcutaneous fat, abdominal fat, mammary gland, Iongissimus dorsi muscle, dorsal deltoid muscle, heart, liver, spleen, lung, kidney, ileum and duodenum. [ Conclusion] The wide distribution of H-FABP gene suggests that its functions are important and multiple.展开更多

[Method] With the stem tip of stolon as material, the influence factom of rooting and the effects of different transplanting substrata on survival rate was investigated. [Result] The results showed that: 1/2MS was the best concentration for rooting and the rooting rate could reach 100%. IBA was better than IAA for rooting on growth regu- lator levdls, and it had the best effect on rooting with 0.3 mg/L, which produced the thickest and most-fibrous roots. Activated carbon had positive influences on the growth of roots, and the suitable concentration of activated carbon was 0.5 mg/l_ for rooting. The study found that survival rate of tissue culture seedlings was obviously higher in the combination of perlite and vermiculite than that in the combination of humus and sand, and the survival rate could reach 98.1% (perlite:vermiculite=l:l). Seedlings in various transplanting substrata could normally bloom, fruit and form stolons. [Conclusion] The study provided technical support for achieving large-scale production of virus-free strawberry and quickly cultivating good seedlings.展开更多

The research was conducted in two main directions: the evaluation of historical transformations of state borders of Georgia throughout of XIX-XX centuries and identification the leading geographical factors. Special emphasis has been made on geographical and cartometric analysis of modern state border of Georgia. In order to identify the historical transformations of state border that have used different methods as well as GIS-technologies, the research is based on the historical, cartographical and statistical data. On the base of a lot of cartographic sources, it is concluded that the borderline in modem topographic maps is often plotted by ignoring the international practice related to plotting the state borders across the physical-geographical objects. This is why the geographical factor seems important in the historical transformations of the state border creating similarly a negative perspective in the future. The main results of research are: (1) classification of geographical factors causing the transformations of the state borders; (2) Evaluation of sensitivity of state border; and (3) creation of DB of the state border of Georgia, allowing continuing the studies in the future.展开更多

The somaclonal showed reduced vegetative vigour without any variation of the natural tree's architecture. The rootstock 'Gisela 6' caused change in genotype habitus inducing a spreading shape, while 'Colt' increased trunk diameter and height. Fruit quality and size were not affected by genotype nor rootstock. 'Gisela 6', from these preliminary data, had proved the most suitable rootstock for both genotypes since it reduced the tree size and vigor and induced early bearing and the production of a greater number of fruiting spurs.展开更多

Quantitative content of phenolic compounds and antiradical efficiency of Kakhethian wines were studied and findings are compared to the appropriate data of the European wines. Analysis showed Kakhethian wines to considerably surpass the European wines with regard to total phenolics compounds: 1,330-2,430 mg/L (Kakhethian white wines), 210-468 mg/L (European white wines), 2,898-4,416 mg/L (Kakhethian red wines), 1,630-2,340 mg/L (European red wines). Average value of antiradical efficiency of white and red wines of Kakhethian type was found to exceed the average value of antiradical efficiency of white and red wines of European type, by 2.3 and 1.7 times, respectively. Georgian wines in the world market are submitted in an insufficient measure, and the purpose of this work is r^v~alino their naritiv~ a,nlitie~展开更多

Determining the factors influencing grain yield in Jilin Province and the weights of their contribution are a very important task, because Jilin Province is an important agriculture base in China. In this study, the accumulation factor sequence evaluating data method was used to analyze the climate and economic-technical factor contribution weights to grain yield and grain yield changes in each city of Jilin Province. Climate yield was also estimated to study the climate effect on the grain yield, and it was calculated in two ways: an improved algorithm and a traditional quadratic method. The results show that the climate and economicechnical factors have different contribution weights to grain yield in different cities in Jilin Province. The contribution weight of the climate factor to grain yield was 0.212-0.349, while that the economic-technical factor was 0.651-0.788. Furthermore, the changes of the climate factor contributing to grain yield changes accounted for 0.296-0.546, and the changes of the economic-technical factor accounted for 0.454-0.704. The weights of climate and economic-technical factor contributing to grain yield are very different between the eastern and western cities in Jilin Province, but their weights contributing to the grain yield change are similar in these cities. In general, the amount of fertilizer used per hectare (FUPH) is the main factor affecting grain yields and yield changes from 1980 to 2008. It is noted that when the FUPH growth rate stabilized after 1995, the effects of the climate factor on the grain yield become more obvious than before. The improved algorithm is effective for esti- mating climate yield in Jilin Province, and the climate yields were mostly between -500 kg/ha and 500 kg/ha, and showed a slightly rising trend in most cities.展开更多

He created a solid legal basis for the country and regulated the ecclesiastic area. He was in West Georgia in 1329-1332/1333. The llkhanid coin was not minted in Georgia during that period; yet, soon the king of Georgia, which had already been united by that time, restored relations with llkhanids and returned to Tbilisi, which implied making the already united Georgia subject to Mongols. Ilkhanid coins and later, coins of Chobanids, the Golden Horde and Jalayirids circulated during the reign of George the Brdhant. In 1338-1339 George the Brilliant conquered Ossetia and Ilkhanid coins were disseminated on the territory of the Golden Horde after that. Formally, Georgia remained under the control of Ilkhanids, which was replaced by Chobanids in 1338 and the governors of the Golden Horde in 757/1356; and in parallel and afterwards by Jalayirids, which is evidenced by written sources as well as numismatic data; Despite formal dependence on the foreign power, which is evidenced by the deployment of 10,000 troops at the border of Georgia as well, the country enjoyed a rather wide internal autonomy. Participation of George the Brilliant in sending envoys for the purpose of the redemption of the Jvari (Cross) Monastery in Palestine in 1316/7, 1320 cannot be assumed. It seems that in those years envoys were sent by Constantine, the king of West Georgia. All the above do not diminish the merits of George V to the Georgian nation and his historic role in terms of the political unification of the country, the creation of a legal basis for it and the regulation of ecclesiastic affairs--the accomplishments of the king, who deservedly bears the name "the Brilliant".展开更多
