S excellent lines were gained by selection breeding in 2004, they are lines of J-5、 J-2、 GX-14、 J-1、 C-6 and C-2. These lines have relatively high Arteannuin content and small variance coefficient, besides morphological character is almost the same between the individuals of the same breeding line.
One 3,5-dinitrobenzoic acid-degrading bacterium A3, isolated from waste water treating system of nitrobenzoic compounds, was identified preliminarily as Comamonas testosteroni based on its morphological characters, physiological and biochemical analyses and 16S rDNA series same source analysis.
(2) By using the method of numerical statistics , the authors studied 18 morphological characters of 67 individuals from 9 populations from different habitats. The results suggested that the overall morphological differentiation of Paris thibetica Franch var. thibetica and Paris thibetica Franch var.apetala Hand.
(2)对不同生境下黑籽重楼(P. thibetica var. thibetica)和无瓣黑籽重楼(Paris Thibetica Franch var. apetala Hand. —Maza)9个居群67个体的18项形态特征结合数量统计方法进行了研究。
Results: ①The α + 6 Thy 1 + c kit - and β + 1 Thy 1 + c kit - cells were relatively uniform subpopulations in size and morphology, which represented about 2%～3% and 0.5 %～1% of the unsorted testis cells, respectively.
The formation factors, morphology characteristics of δ ferrite in precipitation hardening stainless steel 17-4PH have been studied. The optimum chemical composition of steel (%): C 0. 030~0. 045, Cr15. 8~16. 4, Ni 4. 10~4. 50, Ti,Al and N no more than 0. 05, and the optimum solid solution temperature1050℃ were obtained.
The sap flow measurement was used in combination with morphological characteristics of tree and forest structure to calculate the whole-tree transpiration (E), stand transpiration (Et), and mean canopy stomatal conductance (gc).
There was no distinctive difference in proportions of morphological characteristics among them.
Species with similar morphological characteristics and from the same areas or neighboring geographical regions were clustered together and had close relationships.
Taking the physiological and biochemical traits, the morphological characteristics and 16S rDNA sequence into consideration, the isolate Rennanqilyf33 is a new species.
Four variants of the fungus differed in morphological characteristics and glucose oxidase synthesis.
The genotype at these loci was found to have no constant influence on the dynamics of variation in any morphological character.
Accurate species identification of Arbuscular mycorrhizal fungi (AMF) colonized in plant roots is the comerstone of mycorrhizal study, yet this fundamental step is impossible through its morphological character alone.
The results showed that the morphological character of B16 cells treated with CH50 changed greatly and the number of B16 cells treated with CH50 decreased significantly (P>amp;lt;0.05).
We have constructed a partial linkage map including 3 morphological character genes, 4 disease resistance genes, 56 RFLP loci, 4 microsatellite loci and 2 RAPD loci.
Segregation of 48 genetic markers, including one CMS restorer gene, one morphological character gene, six isozymes and 40 RAPD loci, was scored in a backcross progeny of an interspecific hybrid H.
Morphological Component Analysis (MCA) is a new method which takes advantage of the sparse representation of structured data in large overcomplete dictionaries to separate features in the data based on the diversity of their morphology.
The photophysical properties and morphology of fluorene-alt-benzene based conjugated polymer
The UV-vis absorption and fluorescence spectra, thermal stability of spectral property, phase transition behavior and morphology of the synthesized polymers were investigated.
TEM observations indicate that solvent-cast thin deposits of all the polymers show typical fibrillar morphology.
The effect of the ratio of DMF to water on the multilayer growth, structure and surface morphology was studied in some details.
