Lilium lancifolium Thunb. exhibits wide genetic diversity and numerous genetic traits within progeny populations. Parent morphology affects the distribution and assortment of progeny phenotypes. In this study, morphological analysis and fluorescence in situ hybridization (FISH) were conducted for cross progeny (F1 and BC1). Results showed that F1-1 hybrids had greater plant height than the parents; however, backcross progeny plant height (group 1) was low. Leaf number in both groups was considerably low in F1 hybrid, although high in backcrossed plants. Flower number and days to flower opening were intermediate to those of the parents for F1 hybrids, yet low in BC1 progeny. In group 1, backcross progeny showed small bulb length; however, group 2 progeny showed large bulb length. Positive and negative correlations between the phenotypic traits of parents and progeny confirmed significant variations. According to FISH results, F1-1 and F1-2 hybrids distinctly exhibited nine and eight 45S rDNA loci which were same in position with 45S loci of the parents. In backcross progeny, eight 45S rDNA signals were detected in four BC1 progeny of group 1, while 10 signals were observed in all group 2 progeny, same with the L. lancifolium karyotype. Morphological analysis and FISH helped in scrutinising progeny to obtain hybrids with desirable characteristics. 相似文献

Although considered relatively common in horses, there is little information on the prevalence, distribution and aetiology of peripheral caries of the equine cheek teeth (CT). The objective of this study was to investigate a possible association between this lesion and diastemata or 'gaps' between the CT which facilitate the entrapment of food material. Video recordings of oroscopic examinations of all dental cases at an equine hospital over a 3-year period were reviewed, and the location of all diastemata, peripheral caries, trapped food, and of gingival recession were recorded. A total of 108 cases met study inclusion criteria and 298 diastemata and 445 CT with peripheral caries were noted. Diastemata were found predominantly in the mandibular arcades (80%) and 75% of animals had at least one diastema. Peripheral caries was uniformly distributed between the maxillary and mandibular CT, being most prevalent on the most caudal three teeth (87%). Overall, diastemata were not associated with peripheral caries at either a tooth or individual patient level. However, a highly significant association was found between the presence of trapped food within diastemata and gingival recession. 相似文献

Extract Sir, — As from October 1976, all sheep in this country will have to be stunned prior to slaughter. Until recently it had been widely assumed that some form of electrical stunning would be the only practical method for use in New Zealand freezing works. Although for several years electrical stunning has been used for pigs in this country and other classes of stock overseas, only one meat export works in New Zealand has been stunning sheep electrically as a routine procedure for a complete season. 相似文献

Extract Sir,—The surgery tables at present commercially available in New Zealand are fixed in one position, though some may have their height altered by a hydraulic pump or other means. It is considered that the following conditions should be met by a surgery table. 相似文献

Continual discharge of textile wastewaters loaded with a variety of synthetic dyes and metals is considered as a huge threat to surrounding ecosystems. In order to treat these undesirable pollutants, microbial bioremediation is considered as an efficient and economical technique. This study was conducted to evaluate the use of bacterial strains for simultaneous removal of azo dyes and hexavalent chromium [Cr(VI)]. Fifty-eight bacterial strains were isolated from Paharang drain wastewater and tested for their potential to decolorize reactive red-120 (RR-120) in the presence of 25 mg L?1 of Cr(VI). Among the tested isolates, FA10 decolorized the RR-120 most efficiently and was identified as Acinetobacter junii strain FA10. Based on quadratic polynomial equation and response surfaces given by the response surface methodology (RSM), Cr concentration and pH were found to be the main factors governing the RR-120 decolorization by FA10. The strain FA10 also exhibited a substantial salt resistance since it showed a considerable decolorization of RR-120 even in the presence of 150 g L?1 of NaCl. Moreover, the strain FA10 also showed the potential to simultaneously remove the Cr(VI) and the selected azo dyes in the same medium. More than 80 % of the initially added Cr(VI) was removed over 72 h of incubation along with the appreciable decolorization efficiency. The strain FA10 also exhibited good tolerance to considerable levels of different heavy metals. The findings of this study suggest that the strain FA10 might serve as an efficient bioresource to develop the biotechnological approaches for simultaneous removal of different azo dyes and heavy metals including Cr(VI). 相似文献

The instrumentation and technique for reimplantation of the left lung of 6 dogs was described in detail. Thoracic radiographs made during the first 3 postoperative days consistently showed scattered areas of consolidation in the 3 left lung lobes characteristic of alveolar and interstitial infiltrates. Following a peak reaction at 3–5 days postoperatively, the infiltrates gradually resolved at a variable rate and disappeared completely within 2 weeks. All dogs were euthanized 14 days after operation and postmortem examinations were performed. No stenosis was noted in the bronchial, arterial, and atrial anastomoses. Histopathologic examination by light microscopy of lung tissue indicated no abnormalities. Arterial blood gases and pH, and mean pulmonary artery and pulmonary wedge pressures determined immediately prior to euthanasia were within normal limits. 相似文献
