A near-infrared reflectance spectroscopy–based nondestructive technique for the detection of seed-borne fungi in choy sum (Brassica chinensis var. Parchinensis)

In the present study seed-born fungi in choy sum (Brassica Chinensis Var. Parchinensis) was detected through a near-infrared reflectance spectroscopy–based nondestructive technique. Four common species of seed-borne namely, Penicillium decumbens, namyslowskii, Lichtheimia corymbifera, and Aspergillus niger were found to grow southern China. A novel finding that P. decumbens had greatest inhibition germination Choy seeds, resulting non-germination rate exceeding 62.8%. The existing standardized seed sterilization treatment failed completely kill so way nondestructively identify filter out decumbens–infected seeds wereevolved is urgently needed. Near-infrared partial least squares–discriminant analysis (PLS-DA) model achieved discrimination accuracy 95% on-line detection seeds. By detailing design application an innovative product, this lays foundation for development intelligent equipment, it provides decision-making basis breeding industrialization germplasm supervision.
