“…The results corroborate with those of Casaroli et al (2006), who, when working with lots of pumpkin seeds produced in agroecological systems and in conventional systems, treated and untreated, observed that the lots of agroecological systems presented greater contamination by fungi, mainly of the genus Rhizopus and Penicillium. Paiva et al (2016), when evaluating the physiological and sanitary quality of lettuce seeds, also found high amounts of the genus, Rhizopus in the seeds, although it did not interfere with the germination performance at the laboratory.…”

Farmer's dominance depends on seed processing practices that allow seed longevity and sanity throughout storage. In organic systems, seeds cannot be exposed to chemical pesticides. Therefore, organic seed treatment must be conducted by applying techniques which do not contaminate seeds and that can provide physiological and sanitary quality, and also a safe storage. This work aimed to evaluate the physiological and sanitary quality of pumpkin seeds frozen at -18°C and cooled at 15°C, for 36 h and 7 days in polyethylene terephthalate (PET) bottles and in plastic bags with vacuum. Results showed that freezing seeds at -18°C for 36 h in PET bottle provided an increase in the first count of germination and seedling length reduction. The physiological and sanitary qualities of pumpkin seeds frozen at -18°C for 36 h in PET bottle and stored for up to six months under ambient conditions and in a cold chamber were also evaluated. Refrigerated storage provided increased seed viability as compared to ambient storage. In the sixth month of storage, a reduction of the genera Aspergillus and Penicillium occurred in both environments.

Crop cultivation begins with direct sowing or seedlings production; it is important to use high quality seeds, highlighting physiological and health attributes. This study aimed to evaluate the physiological and health quality of watermelon seeds using different methodologies. We used four lots of untreated watermelon seeds of Crimson Sweet plant variety produced in the same year. Physiological performance was evaluated by a standard germination test, first count of germination, accelerated aging, electrical conductivity of seeds (Ec) and seedling emergence (S). Health quality was evaluated by a blotter method test where seeds were planted on well water-soaked blotters (filter papers), and incubated for seven days at 22ºC under 12h alternating cycles of light and darkness; seedling symptom in paper roll test where seeds were planted such as a standard germination test, and incubated for seven days at 22ºC under 12h alternating cycles of light and darkness; seedling symptom in autoclaved sand carried out with the seedlings' emergence. First count of germination and electrical conductivity of seeds showed the lower quality of lots 1 and 2 in relation to the other lots, which were evaluated as similar in seedlings' emergence. Identification of seedlings' symptoms in paper roll and sand was not sensitive enough to quantify Aspergillus sp., Penicillium sp. and Rhizopus sp. presence in watermelon seeds. Electrical conductivity and first count of germination tests allow the evaluation of physiological performance of watermelon seeds properly, based on the correlation value (+/-1). The blotter test is the most efficient test to evaluate health quality of watermelon seeds. Aspergillus sp. incidence is correlated with low physiological performance of watermelon seeds.

“…Silva et al 2012found that there is no difference in seed vigor of coriander obtained from an organic management system and a conventional one. Casaroli et al (2006) also obtained squash seeds with similar quality in the two management systems, and seeds obtained by management practices without the use of synthetic products were more contaminated by pathogens. Nogueira et al (2017) obtained organic seeds of bell pepper without structural pruning and performed harvest at 51 days after anthesis.…”

The quality of seeds produced is the result of the management practices used and environmental conditions during growing. The aim of this study was to evaluate the physiological potential and the health of soybean seeds produced in an organic and conventional system. The genotypes UEL 110 and 122 and BRS 257 and 284 were tested in organic and conventional systems in a randomized block design. The following characteristics were evaluated: moisture content; thousand seed weight (TSW); germination (G) and first count of germination (FCG); tetrazolium (TZ); classification, length, and dry matter of seedlings; and seed health. Analysis of variance was performed separately for the management systems, followed by combined analysis. When significant, the Tukey test (p<0.05) was applied. Multivariate analysis was performed using R software. There was not significance between genotypes and management systems. The conventional management system performed positively for the characteristics TSW, G, TZ, FCG, classification, and length and dry matter of seedling roots, as well as for plant health. The UEL genotypes obtained higher TSW; UEL 110, lower germination; and BRS 257, a smaller number of ungerminated seeds and higher infestation by Cladosporium spp. The seeds produced under the organic system have greater weight and lower infestation by contaminants, whereas the conventional system produces seeds of better physiological quality and lower contamination by Phomopsis and bacteria. The genotype BRS 257 may have seeds multiplied in the organic and conventional management systems.
