Basic research on nondestruction measurement of the active component in crop by near infrared radiation analytical equipment

摘要

In this paper, as basic research on the development of nondestructive analysis equipment for nutritional diagnosis and quality assessment in crops, the absorption spectrum of mango fruit was measured using a near infrared radiation (NIR) and the calibration curve was made, and finaly the wavelength was determined as for measurement of fruit sugar content. In addition, photosynthetic rate, transpiration rate, and water potential of the leaf was measured using the pot-cultivating sugarcane plants under water stress conditions, then the calibration curve were developed in order to estimate such physiological parameters in the field using the NIR.
