The steady dead generation and time that was caused by the isolated virus was certain by chicken embryo which was inoculated on seven or nine days. the histopathological changs of the infectious stunting syndrom were studied by the way of ordinary paraffin section and he dying. the experimental result were as follows : the test proved that the changes of the chicken embryo were different in different stage. the chicken embryo dead in a week after it inoculated. the body was dropsy and hemorrhage. dead before it hatched out, the embyo body were dropsy, pale and slime. the liver was yellow and swolled, gallbladder ( vesica fellea ) was filled with bile. bursa and glandula thymus analosis. the kindey dropsy. bowel lamina were humble, dilatation. gas and yellow foam were filled the bowel. histopathological changes were that, in early stage, obvious changes of liver and kindey were dropsy, hemorrhage and necrosis. two types eosinophilic intranuclear inclusion bodies including large round and little granular were present in cells of the above organs. the obvious changes of bursa were dropsy, adverse folliiculated growth and little lymphocytes proliferating, 19 - 21 days chicken embryo, one or two big empty vacuoles were prensent in cells of liver and kindey. the number of the folliculi was growing, the vacuoles between cells were larger

Shaking flask experiments and hplc analyses showed that 99 isolates still produced four components of avermectins b, in which the yields of avermectins b in 82 isolates were only about 0. 1 ~ 2 % of those produced by the parental strain olm73 - 12. 2 of 82 isolates were confirmed to be the correct gene replacement mutants by pcr and sequence analysis. the mutant only producing avermectins bl was not detected

In a confidential study leaked to the french press, the capital ' s transport authority ratp estimated an average 61 suicide attempts a year cost it in the region of ? 9m ? 6. 2m in emergency interventions and network disruption, plus the severe but often unquantifiable trauma suffered by staff who witness an attempt. christmas and new year are peak periods, with three times the monthly norm, said the report, extracts of which were published in the newspaper le parisien

This study was conducted to examine the interrelationship of 10 seed vigor traits in 12 wheat genotypes through variance, co - variance and path coefficient analysis, to determine broad - sense heritability, and to estimate genetic advance under selection. the genotypes showed significant difference for all traits, except for percentage of normal seedling. genetic correlation between conversion efficiency of seed reserve, electrical conductivity with other traits were not significant, showed that selection for any of them might be possible without hampering any other traits. however path coefficient analysis indicated that conversion efficiency of seed reserve, seed reserve utilization ratio have strong direct effect in affecting seedling weight, and that mean germination time has significantly negatively correlated in affecting gi. moderate to high estimates of broad - sense heritability, genetic coefficient of variation and expected genetic advance were obtained for electrical conductivity, germination index, mean germination time, seed dry weigh, seedling dry weigh, seed reserve depletion ratio indicating the possibility for improving these traits
