to investigate the genetic diversity of persian walnut (juglans regia), 608 different walnut genotypes of neyriz region were evaluated for 30 morphological characteristics including kernel color, fruit shape, shell seal, shell texture and kernel plumpness, kernel weight, percentage of kernel as well as thickness of shell. the correlation between was traits in most cases significant at either 1 ...

In the present work, the simultaneous determination of Brilliant green (BG) and Crystal violet (CV) dyes with overlapped absorption spectra in binary mixture solution, was carreid out using the partial least squares (PLS) and direct ortogonal signal correction-partial least squares (DOSC-PLS) methods. The results obtained indicate that by applying DOSC on the calibration and prediction data for...
