摘要

利用栽培茄子品种与紫茄背交的部分基因型，研究了寄主植物对茄子茎、果螟虫抗性的生化基础。在种间杂交及其亲本的基因型中，观察到过氧化物酶、多酚氧化酶、总酚和茄碱等生化成分含量的不同水平。多酚氧化酶活性在f6 EP65与紫葡萄种间杂交中较高。生化成分水平与茎、果螟虫发病率有明显的相关性。本研究不仅揭示了产生抗性的生化参数，而且还发现了具有抗性的优良基因型的发育。

The biochemical basis of shoot and fruit borer resistance in interspecific progenies of brinjal (Solanum melongena)

The biochemical basis of host plant resistance for shoot and fruit borer of brinjal was investigated using selected genotypes from the back crosses involving cultivated brinjal varieties and Solanum viarum. The different levels of biochemical constituents namely peroxidase, poly phenol oxidase, total phenols, and solasodine contents were observed in genotypes derived from inter-specific crosses and their parents. A higher level of polyphenol oxidase activity was observed in interspecific cross F 6 EP65 x S. viarum. There was a clear correlation between the levels of biochemical constituents and shoot and fruit borer incidence. This study showed the biochemical parameters responsible for the resistance but showed as well the development of superior genotypes with resistance to shoot and fruit borer.

期刊介绍： EurAsian Journal of BioSciences (Abbrev. Eurasia J Biosci or EJOBIOS) is an international, refereed electronic journal. It publishes the results of original research in the field of biological sciences restricted tomorphology, physiology, genetics, taxonomy, ecology and biogeography of both prokaryotic and eucaryotic organisms. The journal encourages submission of manuscripts dealing with plant biology, animal biology, plant physiology, microbiology, hydrobiology, ecology and environmental science, ethnobiology, biodiversity and conservation biology. EurAsian Journal of BioSciences publishes original articles in the following areas: -Agriculture, Fisheries & Food -Anatomy & Morphology -Behavioural Sciences -Biology, Biochemistry and Biotechnology -Biophysics -Biology Education -Cellular Biology and Anatomical Sciences -Ecology, Evolution & Environment -Entomology -Forestry -General Biology -Genetics & Heredity -Life Sciences - Other topics -Microbiology and Immunology -Molecular Biology -Mycology -Palaeontology -Parasitology -Pharmacology & Pharmacy -Physiology and Related Sciences -Plant Sciences -Toxicology -Veterinary Sciences -Virology -Zoology
