| isolation and characterization of rice straw degrading streptomyces griseorubens c-5. | to reutilize rice straw generated during the agricultural production process, the actinomycete strain c-5 was isolated from soil that was under the stook for several years in the heilongjiang province of china by using multiple selective culture media. strain c-5 was identified as streptomyces griseorubens by china general microbiological culture collection center (cgmcc) through morphological and physiological characterization combined with the result of 16s rrna gene sequence and data analysis ... | 2010 | 19597946 |
| variation of the light stable isotopes in the superior and inferior grains of rice (oryza sativa l.) with different geographical origins. | trying to explore a new research angle to increase the resolution and accessibility of isotopic based traceability technique, light stable isotopes (δ(13)c, δ(15)n, δd and δ(18)o) in the superior (ss) and inferior (is) grains of a rice cultivar daohuaxiang were analyzed with relatively limited sample numbers and adjacent sites in fujin and wuchang, heilongjiang province, pr china. distribution of δ(13)c, δ(15)n and δ(18)o in the ss and is grains were found to be different. δ(18)o and δd can disc ... | 2016 | 27173539 |
| change in soil organic carbon between 1981 and 2011 in croplands of heilongjiang province, northeast china. | soil organic carbon (soc) is fundamental for mitigating climate change as well as improving soil fertility. databases of soc obtained from soil surveys in 1981 and 2011 were used to assess soc change (0-20 cm) in croplands of heilongjiang province in northeast china. three counties (lindian, hailun and baoqing) were selected as typical croplands representing major soil types and land use types in the region. | 2016 | 25885969 |
| combinations of hd2 and hd4 genes determine rice adaptability to heilongjiang province, northern limit of china. | heading date is a key trait in rice domestication and adaption, and a number of quantitative trait loci (qtls) have been identified. the rice (oryza sativa l.) cultivars in the heilongjiang province, the northernmost region of china, have to flower extremely early to fulfill their life cycle. however, the critical genes or different gene combinations controlling early flowering in this region have not been determined. qtl and candidate gene analysis revealed that hd2/ghd7.1/osprr37 plays a major ... | 2015 | 25557147 |
