The effect of some fresh‐cut carrot label attributes on consumer purchase intention was evaluated using conjoint analysis. The following three attributes were chosen and manipulated: price (high and low), packaging type (polyethylene bags and expanded polystyrene trays) and production process (organic with certification stamp, organic without certification stamp and no information). A complete factorial design was used, and 12 hypothetical packages of fresh‐cut carrot were developed and evaluated by 96 consumers based on their purchase intention. The consumers were divided into four groups with different opinions. Low price and organic with certification label were the favorite choices of the groups. Only one group preferred expanded polystyrene trays. No interactions were exhibited among the attributes in all groups. 相似文献

Hexose-6-phosphate dehydrogenase (H6PDH-A2; beta-D-glucose:NAD(P)+
oxido-reductase; E.C. 1.1.1.47) of the teleost Fundulus heteroclitus (L.)
shows clinal allelic variation along the east coast of North America. Three
of the major allelic isozymes have been purified and compared for native
molecular weight, subunit molecular weight, isoelectric point, thermal
stability, and steady-state kinetic properties (pH 8.0 and 25 degrees C).
Significant differences were found among the allelic isozymes for
isoelectric point, thermal stability, and some kinetic parameters. The
predominant allelic isozyme in northern populations (H6PDH-AcAc) was found
to be more sensitive to heat denaturation than were the predominant
homozygous allelic isozymes isolated from southern populations (H6PDH-AaAa
and H6PDH-AbAb). The H6PDH-AcAc allelic isozyme had both a significantly
greater Km for glucose-6-phosphate than did either of the southern
phenotypes and a significantly greater Km for NADP+ and Ki of NAD+ than did
one of the southern phenotypes (H6PDH-AaAa). While the allelic isozymes are
functionally nonequivalent, it is not yet known whether these differences
are reflected at higher levels of biological organization.

Woundfin (Plagopterus argentissimus) is one of several endangered warmwater fishes once common to the lower Colorado River basin. Dexter National Fish Hatchery & Technology Center maintains a refugium stock founded in 1982, and augmented with c. 1000 young fish in 1989. Genetic characterization of the refugium stock and salvaged fish from the Virgin River is necessary to develop a strategy to incorporate salvaged fish into the hatchery stock. We developed an enriched microsatellite library and 12 species‐specific polymorphic loci. Alleles per locus ranged from 10 to 19, averaging 13. The average expected and observed heterozygosities were 0.884 and 0.895, respectively. 相似文献
