用近红外光谱法快速无损检测苦豆子和决明子单粒种子生活力的研究
Rapid and Nondestructive Identification of Single Seed Viability of Sophora Alopecuroide and Cassia Tora L Using Near Infrared Spectroscopy
摘要
用傅里叶变换近红外漫反射光谱法测定了自然状态下单粒苦豆子与决明子种子的光谱,并结 合定性偏最小二乘法对这两种种子的生活力进行了鉴别研究。研究结果表明,正反面两次平均光谱的建模效果要优于 单次光谱;采用不同样品建模时,苦豆子与决明子模型的鉴别率均在90%以上。该研究为利用近红外光谱技术快速无 损鉴定种子生活力提供了新的途径。
Abstract
The spectra of both single sophora alopecuroide seed and single cassia tora l seed in natural state are determined by using Fourier transform near infrared diffusion spectroscopy. The viability of both seeds is distinguished by using distinguished partial least squares (DPLS). The result shows that the modeling based on the average spectrum at both side surfaces is better than that based on the single spectrum at one side surface. Both sophora alopecuroide seed model and cassia tora l seed model have an identification rate of 90% at least. This study provides a new method for distinguishing single viable seed rapidly, precisely and nondestructively.
