【摘要】 综述了在增强UV -B辐射下植物响应存在的种内差异 ,这些差异主要包括生长发育、形态结构、生理生化以及UV -B吸收物质 (即经UV -B辐射后体内诱导产生的保护物质 )等方面 ,并初步探讨了差异形成的DNA基础 ,从而为今后的植物防护研究提供理论基础。更多还原

【Abstract】 Researches on UV-B radiation are generalized,especially those on response of plant to UV-B radiation.Under supplementary UV-B radiation,response diversifies within a certain species of plants.The difference may exist in plant development,morphostructure,physiological biochemistry and ultraviolet B absorbing compounds.The mechanism for formation of the differences is also discussed on DNA basis,which may provide some theoretic bases for future research on plant protection.更多还原
