Abstract: 研究内蒙古居群抗寒西伯利亚杏花粉量和花粉萌发率的分布特征及其相关的因素,为生产上授粉树的合理选择提供参考依据。以12个种源同一树龄的178株西伯利亚杏为试验材料,研究其花粉量和花粉萌发率的分布特征。通过方差分析和相关分析对不同花色、花大小、完全花比率、长势与花粉量、花粉萌发率之间的相关性进行分析,并通过自交试验和荧光观察探讨花粉萌发率高低与花粉管在花柱内萌发长度的相关性。结果发现,花粉量和花粉萌发率的分布均呈偏态分布;检测指标之间无相互影响。从花粉育性上讲,仅34.86%的单株最适宜做授粉树。
In order to provide references for reasonable selection of pollination tree in production, the distribution characteristics and related factors of the pollen quantity and pollen germination rate of Armeniaca sibirica with cold-resistance in Inner Mongolia were examined. From 12 provenances, 178 individual plants were collected. Variance and correlation analyses were adopted to investigate correlationships among the relative factors, such as flower color, flower size, perfect flower ratio, growth and pollen quantity, and pollen germination rate. Through self-pollination test and fluorescence microscopic observation, the correlation between the different pollen germination rates and the length of pollen tube in the style was researched. The results showed that the distribution of the pollen quantity and pollen germination rate were in skewed distribution. No interactions were observed among the factors tested. Only 34.86% of individual trees were mostly suitable to be used as pollination trees from the view of pollen fertility
Effects of decomposition of mixed leaf litters of the Castanopsis platyacantha-Schima sinensis forest on soil organic carbon

Abstract: Forest soils contain about 45% carbon(C) of the terrestrial soils,and thereby minor changes of C in forest soils can significantly alter the content of atmosphere carbon dioxide(CO2).Forest litters are the principal source of C pool in forest soils,which can change C and nitrogen(N) transformations by altering the soil moisture,temperature,pH,and nitrogen and N sources into soil during the process of decomposition.However,the effects of forest litters,especially litter mixtures on soil C,including total org...

Abstract: Nine known sesquiterpene lactones, including four lactucin-type guaianolides, four costuslactone-type guaianolides and one germacranolide, were isolated from roots of Lactuca sibirica (Asteraceae), six of which were glycoside derivatives. The chemosystematic significance of the compounds is discussed in the context of sesquiterpenoids present in roots of the closely related species Lactuca tatarica. A comparison of sesquiterpene lactone profiles indicate that the species can be differentiated on the basis of their germacranolide glycoside compositions.

Agriculturae Conspectus Scientificus (ACS) , 2007,
Abstract: Apricot (Prunus armeniaca) osmotic drying set of tests was conducted under controlled condition in laboratory. Current mean values of samples moisture content were obtained by measurement equipment and were used as data base for further statistical analysis. ANOVA statistical analysis proved that solution temperature and concentration are influential factors of osmotic drying. Empirical equation which predicts the changes of apricot halves moisture content in the time as a function of solution temperature and concentration was derived by the means of regression analysis. This equation was evaluated for solution temperatures of 45oC and 55oC, as well as for solution concentrations of 70% and 85% of saturated solution for chosen solution temperature. Results of chemical analyses results for “Keckemetska ruza”, “Novosadska rodna” and “Ambrosia” apricot varieties are also presented in this paper. The significant changes in phosphorous and calcium were not observed, but the contents of total sugar in samples changed during soaking in sugar solution, as a result of solids gain in apricot halves.

International Journal of Molecular Sciences , 2014, DOI: 10.3390/ijms15010377
Abstract: The genetic diversity and population genetic structure of 252 accessions from 21 Prunus sibirica L. populations were investigated using 10 ISSR, SSR, and SRAP markers. The results suggest that the entire population has a relatively high level of genetic diversity, with populations HR and MY showing very high diversity. A low level of inter-population genetic differentiation and a high level of intra-population genetic differentiation was found, which is supported by a moderate level of gene flow, and largely attributable to the cross-pollination and self-incompatibility reproductive system. A STRUCTURE (model-based program) analysis revealed that the 21 populations can be divided into two main groups, mainly based on geographic differences and genetic exchanges. The entire wild Siberia apricot population in China could be divided into two subgroups, including 107 accessions in subgroup (SG) 1 and 147 accessions in SG 2. A Mantel test revealed a significant positive correlation between genetic and geographic distance matrices, and there was a very significant positive correlation among three marker datasets. Overall, we recommend a combination of conservation measures, with ex situ and in situ conservation that includes the construction of a core germplasm repository and the implement of in situ conservation for populations HR, MY, and ZY.

Nigerian Journal of Physiological Sciences , 2006,
Abstract: Intake of nitrosamine - rich food has been implicated in the pathogenesis of childhood type 1 diabetes mellitus. The present study therefore examines a possible relationship between consumption of charred meat, rich in nitrosamine during pregnancy and the corresponding development of type 1 diabetes in their litters. Determination of blood glucose and serum insulin levels in litters showed percent charred meat related increase in the mean blood glucose values of 64.1 +- 1.39mg/dl compared with the mean control value of 53.8 +- 3.78mg/dl and a corresponding reduction in the mean serum insulin values of 2.0 +- 0.43 μU/ml compared with 5.8 +- 0.29 μU/ml in the control (P<0.05). There were no significant changes in the mean blood glucose level and serum insulin level among the corresponding pregnant rats, hence, no evidence of diabetes mellitus. These results suggest that meat, when subjected to charcoal fire roasting may be harzardous to the foetus and a causative factor in the development of type 1 diabetes mellitus in the litters. Key Words: Charred meat, type 1 diabetes mellitus, serum insulin, blood glucose

Abstract: Experiments were carried out to evaluate the effect of water extracts of Fagonia arabica, Salix alba and Anthmis pseudocotula and their mixtures with chemical insecticide (Malathion) on growth of Hyalopterus pruni and characters of Armeniaca vulgaris plants and their soils. The data revealed that F.arabica extract at 20% concentration was the most effective followed by S. alba which recorded 62.66 and 56.16% reduction in H. pruni population density, respectively. While the mixture of Malathion with F.arabica or S. alba or A. pseudocotula extracts (each one at half concentration) results in 57.88, 57.42 and 60.86% reduction in aphid population, respectively. The plant extracts treatment resulted in significant increase in chlorophyll pigments and total carbohydrates in A. vulgaris whereas carotenoids and total protein content decreased (except S. alba extract treatment which increased total protein content). Soil cations; Ca++, Na+, Mg++, K+ and anions; SO4 2-, HCO3 -, Cl- increased with all plant extracts treatment with exception of A. pseudocotula extract treatment that decreased HCO3 - concentrations. This study recommended that natural insecticides were more effective and safe than chemical ones in pest control.
