Sugar content and composition are major criteria used in judging the quality of netted muskmelon (Cucumis melo L. var reticulatus) fruit. Sugar composition and four enzymes of sucrose metabolism were determined in ;Magnum 45' muskmelon fruit at 10-day intervals beginning 10 days after pollination (DAP) until full-slip (35 DAP). Sugar content increased in both outer (green) mesocarp and inner (o...

In order to reveal how sucrose degradation is related to chilling tolerance, two varieties of peach fruit, ‘Zajiao’ and ‘Yulu’, were treated with 1-methylcyclopropene (1-MCP) vapor at 1 μL/L for 24h before storage at 5 oC for 35 and 28 d respectively. ‘Yulu’ peaches had higher sucrose content than ‘Zajiao’ peaches at harvest, but a higher rate of sucrose degradation in untreated ‘Yulu’ fruit ma...

ABSTRACT: In this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. Freeze drying is a separation process based on the  sublimation phenomenon. This process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...

1. A method is described for the sucrose-gradient sedimentation analysis of ribosomes in a post-mitochondrial supernatant of rat skeletal muscle. 2. An essential feature of the method involves the use of buffer of ionic strength 0.3 for homogenization of the muscle tissue. 3. Polyribosomes can be prepared by precipitation from post-mitochondrial supernatant of skeletal muscle by adjustment of t...

An efficient in vitro protocol for plant production of North American ginseng has been established. The pretreatment of cotyledon explants with 1.0 M sucrose at 4◦C resulted in an improvement of embryo quality and, combined with a higher sucrose content (7%) in induction medium, improved the embryogenesis frequency from 40% to 75% and the number of embryos per explant from 10 to 21. The frequen...

Sucrose is an abundant, cheap, and renewable carbohydrate which makes it attractive feedstock for the biotechnological production of chemicals. Escherichia coli W, one few safe E. strains able to metabolize sucrose, was examined pyruvate. The repressor csc regulon deleted in W expressing a variant E1 component pyruvate dehydrogenase complex, these were screened shake flask culture formation fro...

In a base population comprising twenty three Indian “Co” canes and fourteen commercial hybrids from other countries, improvement in sucrose content was obtained over two cycles of recurrent selection. The parental clones had an average sucrose of 19.40%. Among the crosses involving Indian commercial hybrids, the best was CoC 671 x Co 99002 with a maximum record value of 24.0% brix and contribut...
