Effects of genotype,environment, and postharvest storage on the total ascorbate content of potato (Solanum tuberosum) tubers 总被引:1,自引:0,他引:1
The total ascorbate content of potato tubers from 33 Solanum tuberosum genotypes grown at three geographically diverse sites in Europe in each of two years was determined immediately postharvest and after approximately 4 months of storage at 4 degrees C. Statistically significant differences in total ascorbate concentration were observed between genotypes both at harvest and after storage. In all genotypes, the levels of ascorbate decreased during storage. These results are discussed in terms of their implications for diet and health as well as in terms of breeding for improved vitamin C content in potatoes. 相似文献

SUMMARY A case of vaginal prolapse in a South Australian Sea Lion is described. Conservative treatment proved unsuccessful, and an ovariohysterectomy was performed. Problems concerning anaesthesia, surgery and post-operative management of this marine species are discussed. 相似文献

Pheasants hung for 9 d at 10 °G were found to be more acceptable than those hung for 4 d at 15 °G or for 18 d at 5 °G. The birds stored at 15 °G were tough by comparison with those held for longer at the lower temperatures and the clostridia, including Clostridium welchii, increased considerably in the intestines during the storage period. Microbial growth in the muscle tissue was generally found to occur only in birds in which the gut had been perforated by shot. There is an indication that 9 d at 10 °C produced a more “ gamey “ bird than 18 d at 5 °G or 4 d at 15 °G, but the most “ gamey “ birds, independent of temperature, were those in which the muscle was damaged by shot. 相似文献

A RETROSPECTIVE STUDY OF OSTEOMYELITIS IN DOGS AND CATS 总被引:1,自引:0,他引:1
Thirty-nine cases of osteomyelitis in dogs and cats were recorded at the Sydney University Veterinary Hospital and Clinic over a three and a half year period. In 36 cases osteomyelitis was established prior to admission. Three cases of osteomyelitis became established from a total of 502 orthopaedic surgery cases seen at the hospital in this period. In the dog the most common source of infection was open reduction of closed fractures, while in the cat, the most common source of infection was an extension from soft tissue infection. More males than females were affected. Ten cases of osteomyelitis were treated successfully, twelve cases required amputation, while euthanasia was performed on thirteen other cases. The problems and principles of treatment of active osteomyelitis as reflected in the treatment of this series of cases have been described. 相似文献

Experiments on the control of wheat bulb fly larvae by seed dressings compared four organophosphorus compounds in standard siliceous earth formulations with special formulations of the same compounds in polyvinyl acetate, polypropylene or wax. The special formulations allowed more insecticide to be placed on the seeds without affecting germination. Counting shoots damaged by wheat bulb fly larvae showed that: siliceous earth formulations of diazinon gave good control which was not improved by special formulations; control with siliceous earth formulations of dimethoate was poor and was improved only little by the special formulations; and control with siliceous earth formulations of parathion and dichlofenthion was moderate and was improved by special formulations, especially polyvinyl acetate and polypropylene. The results suggest that special formulations are of most value with compounds that are moderately effective but where the amount of insecticide in standard seed dressings cannot be increased without damaging the plants. 相似文献
