萝卜的用途作为模式作物研究植物对环境胁迫的响应，重点介绍了不同大气污染物（O3、SO2、NO2、酸性降水）及其组合对植物响应的影响。对温度、光照、水分胁迫和大气CO2的响应也进行了研究和讨论。此外，参考文献综述的生长条件和建议的最佳范围的环境和文化变量，即光，温度，营养供应的实验方案进行了评估。萝卜生物量分配模式独特，植株沿着径小，短而易栽培，是一种优良的试验植物。肉质地下储存器官，由下胚轴和上部胚根形成，在营养发育过程中充当主要的库。丰富的同化物供应，由于CO2水平升高，随着高辐射经常促进下胚轴生长超过芽生长，而在应力条件下，芽生长维持在下胚轴的费用。这使得萝卜的下胚轴：地上部比率成为一个非常敏感和适用于各种环境胁迫的指标。萝卜作为模式作物的潜在弱点和缺点，特别是伤害和生长反应的高变异性，讨论了沿着可能的解决方案。未来的研究需要来自总结的结果，并从文献综述的结果之间的一些差异。
The use ofRaphanus sativusL. as a model crop for studies on plant response to environmental stresses is reviewed with emphasis on the effects of different atmospheric pollutants (O3, SO2, NO2, acidic precipitation) and their combinations. Responses to temperature, light supply, water stress, and atmospheric CO2are also studied and discussed. In addition, the references reviewed are evaluated in terms of their experimental protocols on growth conditions and recommendations for optimal ranges of environmental and cultural variables, i.e. light, temperature, nutrient supply are given. Its distinct pattern of biomass partitioning, the small dimensions along with short and easy culture make radish an excellent experimental plant. The fleshy below-ground storage organ, formed by the hypocotyl and upper radicle, acts as the major sink during vegetative development. Abundant assimilate supply due to elevated levels of CO2along with high irradiation frequently promote hypocotyl growth more than shoot growth, whereas under conditions of stress shoot growth is maintained at the expense of the hypocotyl. This makes the hypocotyl: shoot ratio of radish a very sensitive and suitable indicator for various environmental stresses. Potential weaknesses and shortcomings of radish in its role as a model crop, particularly the high variability of injury and growth responses, are discussed along with possible solutions. Future research needs are derived from the summarized results presented and from some disparities among findings within the literature reviewed.
