Incremento de área em sementes de moringa durante a embebição por meio da análise de imagens

Abstract: A morfologia das sementes e as modificações físicas sofridas por elas durante a germinação podem estar associadas ao vigor. Por isso, objetivou-se com este trabalho monitorar o incremento de área em sementes de moringa durante a embebição, por meio da análise de imagens, com o intuito de se determinar a sua qualidade fisiológica a partir deste incremento. Utilizaram-se sementes de quatro lotes de moringa com e sem tegumento, fotografadas antes e durante a embebição, nos períodos de 8, 16 e 24 horas, nas temper… Show more

“…As observed by the automated physical analysis, the lots with higher values of tissue density, fi lling, and solidity, presented higher germination and vigor. Similarly, the direct relation between tissue density and / or fi lling with the physiological quality of seeds has already been observed both in forest species such as L. leucocephala (Medeiros et al, 2018), M. polymorphum (Faria et al, 2019) and M. oleifera (Noronha et al, 2019), and in other agricultural species such as tomato ( Borges et al, 2019) and Jatropha curcas (Medeiros et al, 2020).…”

“…However, one of the major requirements in developing machine vision systems for analysing and sorting plant products (e.g., seeds, fruits, or vegetables) is the ability to analyse an image accurately and quickly. Various methods (e.g., use of a CCD camera, flatbed scanner, X-ray scanning, or NMR imaging) can be used to obtain seed images showing external or internal features of certain quality factors, such as size, shape, colours, and defects (Noronha et al, 2019).…”

“…Therefore, the use of the X-ray technique is a viable alternative for evaluating seed vigour (Rahman, 2016). Also, in modifications of embryo reserves (Nielsen, et al, 2017), the percentage of the space occupied by embryo reserves in the internal cavity (Noronha et al, 2019), and physical damage that directly reflects on seed germination and vigour (Abud et al, 2018;Medeiros et al, 2018). Thiago, et al, (2020 worked on the X-ray image analysis of the internal morphology of Vigna radiata seeds and was able to identify various damage types.…”

“…Image analysis of seeds and seedlings is one potential technique, widely used in research, which relates characteristics of seed morphology to seedling performance, thereby expressing seed vigour with greater precision and less subjectivity, affording quick results and where, in most tests, the analysis is nondestructive (MEDEIROS et al, 2019;NORONHA et al, 2019;VASCONCELOS et al, 2018).…”
