Abstract:

In order to investigate the feasibility of predicting the filling power of cut tobacco by near infrared reflectance spectroscopy (NIRS), one hundred and forty samples were collected from twelve flue-cured tobacco varieties in Yunan Province, and the near-infrared spectra and filling power of all samples were measured, PLS models were established with 100 corresponding spectra and filling power. By outer validated with spctra and tested filling power values of forty samples and t-test, T=0.4215, t(0.05,39)=1.6849, T
