The influences of the cultivation conditions and the varieties on the nutrimental information of tomato tree and paddy rice were studied using infrared and X-ray fluorescent spectroscopy, which are nondestructive, simple and rapid methods to get the crop vigor in the field, respectively for the simultaneous measurements of plural modes of nitrogen and the nutrimental elements. The analysis of the relationship between the spectroscopic information of leaves and the element contents could be experimentally possible to spectroscopically quantify the elements. Moreover, the influences of the nutrimental components of the medium for the cultivation of tomato on the spectroscopic information of the leaves were grasped, and the variety characteristics of rice were obtained by the spectroscopic measurement of the leaves. Thus these results suggested that the above spectroscopic methods have the potential to evaluate the crop vigor in combination with the color information. We then paid attention to the color image analysis with a commodious digital camera as easy, nondestructive and cheap sensing method to get the quality of agricultural products, and constructed the continuous monitoring system of the color image that was able to be the remote control with the FieldSrver. As a result, the digital color information was quantitatively monitored with the field environmental conditions. Furthermore, the prototype of "Bioinformation Analytical System on the Internet", which was consisted of the database system with data management, accumulation, and the data retrieval function and of the analytical system to take out significant information for the user from the system, was constructed by structuring the information of agricultural products and foods.

采用红外光谱法和X射线荧光光谱法分别对番茄植株和水稻植株的多种形态氮素和营养元素进行同时测定，研究了栽培条件和品种对番茄植株和水稻植株营养信息的影响。分析叶片的光谱信息与元素含量之间的关系，可以在实验上对元素进行光谱定量。掌握了番茄栽培基质营养成分对叶片光谱信息的影响，并通过叶片光谱测量获得水稻品种特征。这些结果表明，上述光谱方法具有潜力，以评估作物的活力与颜色信息相结合。在此基础上，我们将目光转向了利用便携式数码相机进行彩色图像分析，以实现对农产品质量的简单、无损、廉价的检测，并利用FieldSrver构建了一套可远程控制的彩色图像连续监测系统。结果，根据现场环境条件定量监测数字颜色信息。在此基础上，通过构建农产品和食品信息，构建了“网上生物信息分析系统”的原型，该原型由具有数据管理、积累和检索功能的数据库系统和从系统中提取对用户有意义的信息的分析系统组成。
