    Notes: Malus xiaojinensis, one of the most important wild genotypes in the genus Malus, is resistant to a variety of stresses such as Fe deficiency chlorosis, drought and cold. However, lack of knowledge of its genetic background prevents using genetic analysis to study those agronomic traits and corresponding gene functions. Here, as the first step towards construction of the linkage map of M. xiaojinensis, genetic analysis of the F1 triploid hybrids (M. xiaojinensis × M. baccata) was performed with amplified fragment length polymorphism (AFLP) markers. Using 15 EcoRI- MseI primer combinations, 1110 AFLPs were identified, with 31.3% of M. xiaojinensis-, 12.7% of M. baccata-specific markers, 54.9% of common markers, and 1.2% of non-parental markers; 93.3% of the AFLP markers exhibit the expected segregation ratio. Thirty-two M. xiaojinensis-specific markers and 47 common markers display a 5 : 1 and 11:1 segregation ratios, respectively, suggesting that M. xiaojinensis is an autotetraploid, or at least an isosyndetic allotetraploid.

    Breeding for high yield and fibre quality in coloured cotton (2004)

    Notes: In the present study, three types of coloured fibre cottons, i.e. white, brown and green, were compared for their fibre quality and yield. The comparison of fibre quality suggested that coloured fibre cotton was inferior as compared with white fibre cotton. To understand the effect of cellulose, mineral elements [nitrogen (N), phosphorus (P) and potassium (K)] and pH of fibre cells on the quality of fibre, these components were studied at different fibre cell developed stages in all three fibre cotton types. The cellulose content is closely associated with the quality of fibre. The higher fibre quality of white fibre cotton might be the result of the high cellulose content in it compared with coloured fibre cotton. A rapid and slow decrease in pH in white and coloured cottons, respectively, might have some effects on fibre elongation. Among the mineral contents, potassium is positively correlated with the fibre quality traits. The pigment development patterns in brown and green fibre cottons are not similar. In green fibre cotton it takes more time to deepen in colour as compared with brown fibre cotton. Possible strategies for the improvement in quality of coloured fibre cotton are discussed. The results of heterosis studies in coloured fibre cotton suggest that heterosis could improve yield and quality of coloured fibre cotton. In the present study, the hybrids between ZJU12A x ZJU05R and ZJU18A x ZJU01R, having an acceptable lint colour types plus better fibre quality and high yield performance, may be exploited further for their heterotic advantages.

    A MACHINE VISION SYSTEM USING IMMUNO-FLUORESCENCE MICROSCOPY FOR RAPID RECOGNITION OF SALMONELLA TYPHIMURIUM (2001)

    Notes: The objective of this research was to develop an automated system using image processing and statistical modeling techniques to identify and enumerate bacteria on slides containing Salmonella typhimurium. Pictures of bacterial cells were acquired with a CCD camera attached to a motorized fluorescence microscope. A shape boundary modeling technique, based on the use of circular autoregressive model parameters, was used. A minimum-distance classifier was trained with ten images belonging to each shape class (rod shape and circle shape). Experimental results showed that the model parameters could be used as descriptors of shape boundaries detected in digitized binary images of bacterial cells. In spite of the advantages of human vision, the differences between the computer and a bacteriologist in recognizing and counting of Salmonella cells were less than 8%. The computer analyzed each image in approximately 5 s (a total of 2 h including sample preparation), while the bacteriologist spent an average of 1 min for each image.

    Investigation of permeable fracture zones by tube-wave analysis (1994)

    Notes: In vertical seismic profiling tube waves are generally classified as noise. They have, however, useful applications: tube waves can be generated by compressional waves at fluid-filled cracks crossing the wall of the borehole. In this case the permeability of the fracture zone can be estimated from the amplitude ratio of the incident P wave and the generated tube wave.In the present study an improved model for tube-wave amplitude interpretation is presented. While former models assumed isolated cracks, now, the consideration of fracture zones of a certain porosity, permeability and width is allowed. Master curves are used to check the sensitivity of the amplitude ratio of tube and P waves with respect to the formal parameters of computation. It is shown, moreover, that mainly those parts of a fracture contribute to the tube-wave generation which are within a radius of about 1 m of the borehole.The problem of localization and characterization of fracture zones by tube waves was investigated with several complementary field experiments in shallow boreholes in crystalline rocks as vertical seismic profiling (VSP) with three-component borehole geophones and hydrophones, televiewer measurements, well tests and temperature measurements.It turned out that fracture zones were met at all depths where tube waves were generated. However, not all of them were found to be hydraulically activated during well tests and temperature measurements. This means that fractures detected by tube-wave VSP are not necessarily of hydrological importance. Transmissivity values based on tube-wave analysis are, therefore, an upper limit for the well under consideration. On the other hand, the transmissivity values derived from the well tests agreed quite well with those of the tube-wave analysis if only the ‘open’fracture zones were considered: a fact which seems to confirm our theoretical model.

    Notes: The eggs of Mugil cephalus were significantly larger than those of Epinephelus malabaricus, and E. coioides, while those of Sciaenops ocellatus were intermediate between E. coioides and M. cephalus. The distribution density of pores in the egg envelope of S. ocellatus was significantly different from that of E. malabaricus and E. coioides. The micropyle diameters were significantly different in the four species. The ultrastructure of the zona radiata surface, the distribution density of pores and the size of eggs were also useful characters for distinguishing among the four species, but the ultrastructural features of the micropyles were the most important of all for egg identification.

    Notes: Fresh-cut lettuce inoculated with Salmonella enterica serovar Typhimurium and Escherichia coli O157:H7 was treated using cetylpyridinium chlorine (CPC) solution in a laboratory-scale immersion spray system. With 0.7 kg/cm2 spray pressure and 1.5-min spray time (ST), both bacteria were significantly reduced (P 〈 0.05) in 0.1% to 0.3% CPC spray treatments, compared with water spray controls. At the same ST, increasing spray pressure from 0.7 to 2.1 kg/cm2 further reduced bacteria by 0.5 to 1.5 log colony-forming units (CFU)/g. The 0.2% and 0.3% CPC treatments resulted in the greatest reduction of S. serovar Typhimurium and E. coli O157:H7, respectively. Similar bacterial reduction could be achieved using shorter ST with extended post-spray exposure time. No color change on the lettuce was observed after CPC treatment.

    Notes: : Predictive models for the survival/death of Campylobacter jejuni and Salmonella Typhimurium during poultry scalding and chilling, as functions of temperature (50 to 60 °C), chlorine level (0 to 50 ppm) and water age (0, 10 h for scalding; 0, 8 h for chilling), were evaluated and developed using the data from previous study. As primary models, the Weibull distribution, exponential, logistic, and Gompertz models were compared. The secondary models were developed by modifying the Davey and polynomial models. Mean Square Errors (MSE) and the plots of predicted in contrast to observed survivors showed a good fit and prediction. The Weibull distribution-based secondary model was selected due to its fewer parameters and better prediction (MSEs 〈 0.4) compared to the other models.
