Agrobiodiversity is essential for a sustainable food production, and the knowledge of the potential characteristics of landrace seeds may prompt farmers to adopt the habit of seed conservation for this species. This study aimed at categorizing landrace and commercial common bean (Phaseolus vulgaris L.) accessions, according to the physiological quality (viability and vigor) of seeds produced in the field, during two growing seasons, under organic and conventional farming systems. Germination percentage, field emergence, electrical conductivity, accelerated aging, cold test and seedling length were assessed. The landrace bean accessions exhibit diversity in the physiological seed quality, in terms of their viability and vigor. No differences were observed between the farming systems, in relation to the physiological quality of the seeds produced. The categorization of landrace common bean accessions allows to identify those with superior physiological seed quality.

“…In general, it reduces the test total duration from eight days, or 192h, to four days, or 96h, which represents approximately 50% of time reduction. Additionally it brings to test the benefits of image analysis, with reproducible results, practical procedures and does not involving human error in count evaluations, estimates and measurements (SAKO et al, 2001;HOFFMASTER et al, 2003;HOFFAM-STER et al, 2005 ).According to Barros and Marcos -Filho (1997), Pinto et al (2007) and Santorum et al (2013), there is an increasing need for efficient methods to assess the physiological quality of seeds, which enable decision making regarding the collection, processing, storage and marketing of the crop, and the association of AA and SRL tests could be a great alternative to meet those demands.…”

“…On the other hand, predicting the seed lot performance under suboptimal field conditions is the main goal of seed vigor tests (TEKRONY et al, 1987). In this scenario, the accelerated aging test is considered one of the most sensitive and efficient vigor test for various species (MARCOS-FILHO, 2005).…”

-This study aimed to associate two concepts of seed vigor testing, the aging and seedling growth using image analysis, providing a feasible and time-saving way to evaluate maize seed vigor in large scale. For this purpose, five seed lots with different vigor levels from two single hybrids were used. The seeds were characterized by moisture content, germination, seedling emergence, seedling emergence speed index, accelerated aging and cold tests. The treatments were composed by varying the accelerated aging periods (0, 24, 48, 72 and 96h) and seedling growth periods (48 and 72h), before submitting the seedlings to image analysis for seedling root length measurement. Considering the results obtained, the adaptation of accelerated aging test by reducing the aging duration from 96h to 48h, and the replacement of the germination test by seedling root length measurement using image analysis could be considered a potential tool for maize seed vigor assessment. The treatments composed of 48h of seed aging followed by seedlings root length measurements using image analysis provided reliable data, compared to traditional vigor tests and it could be considered an efficient and timesaving approach, associating two different concepts of seed vigor analysis.Keywords: Zea mays L.

ASSOCIAÇÃO DE TESTES DE VIGOR PARA AVALIAÇÃO PRECISA E EFICIENTE DA QUALIDADE DE SEMENTES DE MILHORESUMO -O experimento teve como objetivo associar conceitos para avaliação do vigor de sementes, o envelhecimento acelerado e crescimento de plântulas medido por meio da análise de imagens. Para tanto, cinco lotes de sementes com diferentes níveis de vigor de dois híbridos simples foram utilizados. As sementes foram caracterizadas pelo teor de água, germinação, porcentagem e índice de velocidade de emergência de plântulas, envelhecimento acelerado e teste de frio. Os tratamentos foram constituídos por diferentes períodos de envelhecimento acelerado (0, 24, 48, 72 e 96h) e de crescimento de plântulas (48 e 72h) e, em seguida, as plântulas, submetidas à análise de imagens para mensuração do comprimento de raízes. A adaptação do teste de envelhecimento acelerado, reduzindo a duração do envelhecimento de 96h para 48h e a substituição do teste de germinação pela mensuração do comprimento de raízes das plântulas por meio da análise de imagens, comprovou-se um método potencial para avaliação da qualidade de sementes de milho. Assim, os tratamentos compostos por 48h de envelhecimento, seguido pela mensuração do comprimento de raízes utilizando a análise de imagens, forneceram dados confiáveis em comparação aos testes de vigor tradicionais e podem ser considerados uma nova abordagem para a análise de vigor de sementes.

“…As seed germination does not always correlate with field emergence, seedling emergence is widely used to predict stand establishment [42]. Early-emerging plants can generally better utilize available resources, including soil moisture in the soil profile [43], and can also successfully compete with weeds.…”

Weed Suppression and Performance of Grain Legumes Following an Irrigated Rice Crop in Southern Australia

Post-rice irrigated soils offer several potential advantages for the growth of subsequent crops, but Australian producers have often been reluctant to grow grain legumes immediately following a rice crop due to physico-chemical constraints. A field experiment was thus conducted to explore the potential for producing grain legumes following rice in comparison to those following a fallow during 2012 and 2013. Two grain legumes, field pea and faba bean, were sown 5, 7 and 12 weeks after rice harvest in 2013 at Yanco, NSW, and plant growth indicators and grain yield were compared. Early sowing of field pea following rice gave the best outcome, with plants flowering three weeks earlier and yielding 1330 kg·ha −1 more grain than after fallow. In contrast, faba bean yield was 35 kg·ha −1 less after rice than after fallow across the three sowing dates. Higher pea yield was consistent with the early emergence of seedlings, higher light interception and overall greater plant growth following rice. Post-rice crops also had 10-fold less weed infestation than crops in a similarly-established fallow treatment and, thus, required far less weed management. Legume crops sown at the later seeding date had significantly reduced (~50%-60%) yields compared to those of the first two sowings; this is most likely a reflection of reduced temperatures and day lengths experienced during vegetative and reproductive growth phases.
