Abstract

The visual record of grain number and size uses  limited samples, causing fatigue and increase of error;  disadvantages that can be solved with the processing and  analysis of digital images (PAID) as proposed in this paper.  In this regard, seeds of five durum wheat cultivars (Triticum  durum Desf.) and five of common wheat (Triticum aestivum  L.) were used. Scanned images were obtained. The PAID  was performed with ImageJ 1.49b, length, width, size  and number of grains were measured in 317 samples. The  time for grain registration was compared between visual  counting, PAID and electromechanical counter. Correlation  analyzes, X2, ANDEVA, and comparison of means were  performed. The grain size of common wheat was from  15.41 to 18.37 mm2, in durum it went from 17.82 to 19.6  mm2 (DMS = 0.385, p≤ 0.01), these were longer (>7.1 mm;  p≤ 0.01) but thinner (DMS = 0.043, p≤ 0.05). The number  of grains observed and calculated showed concordance  (X2= 2.73, p= 1) and close correlation (rs=1, p≤ 0.01).  The counter and visual record of grains number showed  linear increase of time as the sample size increased, while  the PAID required approximately 55 s. Image processing facilitates the individual dimensions of pooled grains and is  an accurate and fast tool for analyzing the size and number  of wheat grains.
