Automated system of seedling image analysis (SVIS) and electrical conductivity to assess sun hemp seed vigor

Abstract

-The development of new procedures for quickly obtaining accurate information on the physiological potential of seed lots is essential for developing quality control programs for the seed industry. In this study, the effectiveness of an automated system of seedling image analysis (Seed Vigor Imaging System -SVIS) in determining the physiological potential of sun hemp seeds and its relationship with electrical conductivity tests, were evaluated. SVIS evaluations were performed three and four days after sowing and data on the vigor index and the length and uniformity of seedling growth were collected. The electrical conductivity test was made on 50 seed replicates placed in containers with 75 mL of deionised water at 25 ºC and readings were taken after 1, 2, 4, 8 and 16 hours of imbibition. Electrical conductivity measurements at 4 or 8 hours and the use of the SVIS on 3-day old seedlings can effectively detect differences in vigor between different sun hemp seed lots.

Avaliação do vigor de sementes de girassol por meio de análise de imagens de plântulas

“…Recentemente, vários trabalhos de pesquisa indicam eficiência do uso de análise computadorizada de plântulas com o sistema SVIS ® na avaliação do vigor de sementes de berinjela (SILVA & CICERO, 2014), trigo (SILVA et al, 2012a), milho doce (ALVARENGA et al, 2012), crotalária (SILVA et al, 2012b), pepino (CHIQUITO et al, 2012), entre outras.…”

Assessment of Seed Vigour Tests for Relative Storability and Field Performance in Cotton

“…It showed that accelerated aging for a period of 48 hours would be appropriate for estimation of storage potential of the seed lots. On assessing seed physiological potential through traditional accelerated aging test, other researchers have also verified reduction on vigor of cotton seeds, during storage, especially under non-controlled environmental conditions (Freitas et al, 2002;Silva et al, 2012); since under such environmental conditions, the seeds are exposed to the fluctuations of temperature and relative humidity, which also contribute to reduction of seed physiological potential. Pourhaadian and Khaajepour (2010) also conducted correlation coefficient and regression relations between seed performance and vigour tests and opined similarly.…”

Rice Seed Germination Analysis

“…Many researchers [1,3,4,7,8,9,10,11,12,13,14,17,19,20,21,24,26,27,29,30,32,34,35,36,37,38,41,42,43,44,45,48,49,50,51] have applied image processing for rice germination in their studies. This is because using image processing is rapid, economic, consistent, and objective.…”
