“…In the present research, although it was observed difference between the physical parameters comparing the seed lots, it did not reflect on the seed quality. In contrast, research with broccoli and leucaena seeds showed a close relationship between variables related to tissue integrity, as well as descriptors of shape and size, with physiological attributes (ABUD et al, 2018;.…”

Global demand for pulses such as the mung bean has grown in the last years. For successful production of these crops it is necessary to use high quality seeds. Methodologies based on X-ray image analysis have been used as a complementary tool to evaluate the physical quality of seeds due to their speed and potential for automation. The aim of this study was to evaluate the efficiency of X-ray analysis for non-destructive evaluation of the physical quality of Vigna radiata seeds and to relate the variables obtained with their physiological potential. For this, seeds from eight lots were X-rayed and subsequently subject to germination test. In total, 18 physical and physiological parameters were determined. The X-ray image analysis was efficient for evaluating the internal morphology of Vigna radiata seeds and allowed the identification of various damage types. However, it was not possible to relate the physical variables to the seed quality as the lots presented similar germination percentage. Physical variables such as solidity and circularity are related to percentage of root protrusion and length of seedling hypocotyl. Low relative densities indicate deteriorated tissues, related to severe morphological damage and non-viable seeds.

“…High tissue density (as classified by the proportional area of seed occupied by the embryo and endosperm) was related to the germination performance of pepper seeds by Gagliardi and Marcos‐Filho () and Dell'Aquila (). Also, the relationship of relative density, extracted from radiograph image analysis with the length of broccoli seedlings was reported previously, referred to as gray density (Abud et al., ).…”

“…The automatization of the analysis of seed radiographies is important for the seed industry as a practical approach (Abud et al., ), as a high number of seed lots needs to be evaluated in a short period of time. Through computer‐aided analysis, variables such as relative density, integrated density, and seed filling, as well as shape descriptors, including area, perimeter, and circularity, can be easily generated by the ImageJ software.…”

Relationship between internal morphology and physiological quality of pepper seeds during fruit maturation and storage

The improvement of existing analyses that access the physiological quality of seeds and the inclusion of nondestructive techniques represent significant progress to the seed sector. Despite being prominent, the use of x‐ray is hindered by the fact that radiographic images are, in general, analyzed subjectively. Therefore, this study aimed at investigating the relationship between the seed internal morphology, accessed via x‐ray images, and the physiological quality of habanero pepper seeds. The seeds were harvested from fruits at three maturity stages and then kept in post‐harvest storage for different periods. Initially, radiographs were generated and subjected to automated image analysis, using the ImageJ software. The parameters area, perimeter, circularity, relative density, integrated density, and percentage of seed filling were evaluated. After the x‐ray testing, the seeds were tested for germination and vigor. It was observed that postharvest storage increased the relative density of seed tissues, as well as seed filling and germination for all stages of maturity. Positive and significant correlations were found between tissue density parameters, evaluated by image analysis, with seed germination, germination speed and seed viability, while negative correlations were observed with seed dormancy. In general, the automated radiograph analysis of habanero pepper seeds is a promising method to obtain physical variables of seeds, such as relative density, integrated density, and seed filling. Habanero pepper seeds obtained from yellow and orange fruits exhibit higher physiological quality. The storage of these fruits after harvested before seed extraction is a good alternative to improve the seed physiological quality.

“…The others variables describing whole seed and embryo size and shape also detected significant variations between These variables related to morphometric characters have a great importance for breeding programs and may correlate with physiological attributes. In studies with broccoli, Abud et al [4] observed that seeds area and circularity correlated significantly with seedlings length, indicating a possibility of using these variables to infer data on physiological quality.…”

“…Recent studies have demonstrated the efficiency of X-ray technique for application in various studies with seeds [4][5][6][7]. However, the radiographs analysis may be compromised when radiographic images are evaluated by human visual, since the process is slow and can generate interpretation errors [6].…”

The application of modern and efficient techniques to access seed physical and physiological information has contributed to new advances in the agricultural sector. The objective of this study was to evaluate morphometric parameters obtained from the X-Ray analysis using crambe seeds harvested at different maturation stages and to relate them to seed physiological potential. Seeds harvested at different maturation stages were evaluated using X-Ray test, germination, first germination count, germination speed index, root protrusion velocity and accelerated aging. The Principal Components Analysis was applied to data collected. The results demonstrated that the X-Ray analysis allowed to visualize internal morphology of crambe seeds. Differences between seeds harvested at different maturation levels were observed. Correlations between physical variables were verified, such as seed area with germination (r = 0.96). The use of X-Ray analysis combined with semi-automated analysis is efficient to differentiate crambe seeds in different maturation stages. The morphometric parameters are related to the physiological quality of crambe seeds.
