“…The microenvironment may contain more carbon released from root due to plant growth and metabolism (Hu & St. Leger 2002;Bruck 2005). Meanwhile, this study suggests that M. a isopliae inoculated by conidia-suspensiondrenching or conidia-coating had no effect on the germination of peanut seeds, similarly to the results by Kabaluk and Ericsson (2007) in corn and by Diniz et al (2009) in sweet pepper. The process of seed germination contains a series of orderly physiological and biochemical reactions and morphological changes that are regulated by genetics.…”

The benefit of the entomopathogen Metarhizium anisopliae to early root development was evaluated. Two inoculating methods, conidia-suspension-drenching (T 1 ) and conidia-coating (T 2 ), were used when sowing peanut. The results showed that taproot length and lateral root number in T 1 significantly increased compared to the control (T 0 ) in days 4-10 after treatment, whereas no significant difference was found between T 2 and T 0 . The fungal density by T 1 and T 2 fluctuated in the first 8 days, followed by a gradual decline. The ratio of the taproot length or lateral root number in T 1 and T 0 was significant relative to the fungal persistence. It suggested that M. anisopliae promotes peanut root development and should be considered as important factor in plant protection besides pest controls.

“…Seeds of sweet pepper (Capsicum annum) and of sweet corn (Zea mays L.) treated with gibberellic acid presented higher germination, as well (ARAGÃO et al, 2003;DINIZ et al, 2009). Such behavior may be explained by the fact that gibberellins promote growth by increasing the plasticity of the cell wall followed by hydrolysis of starch into sugar, which reduces the water potential in the cell, resulting in entry of water therein and promoting elongation (ARTECA, 1996).…”

The germination of pepper seeds, even under favorable conditions, is slow and disuniform, requiring the use of techniques which help to speed up the germination and uniform emergence in the field. The study aimed to evaluate the effect of different plant growth regulators on seed germination tabasco pepper (Capsicum frutescens L.) The experimental design was completely randomized in factorial scheme 2 (pre-soaking) x 5 (plant growth regulators). There were four replicates of 50 seeds for each treatment. The plant regulators used were (1) Stimulate ® , Stoller; (2) Sett ® , Stoller;(3) CaB ® , Stoller; (4) Progibb ® , Valent Biosciences; (5) distilled water, which was used a volume of 13 ml of solution for all treatments. The seeds were pre-soaked for 24 hours or germinated directly in solutions with plant growth regulators. The seeds were submitted to germination test in gerbox in germinators at 25 °C for 19 days. The pre-soaked tabasco pepper seeds had higher percentage of germination, of normal seedlings and seedling growth, regardless of the pre-soaking solution. The growth regulators Progibb ® and Stimulate ® improved seed germination and early growth of seedlings of tabasco pepper. The use of any one of the bioregulators evaluated stimulated the development of roots. Reguladores del crecimiento de plantas en la germinación de semillas de pimienta tabascoPalabras clave: Capsicum frutescens; reguladores del crecimiento; imbibición Reguladores vegetais na germinação de sementes de pimenta-tabasco Resumo A germinação de sementes de pimenta, mesmo em condições favoráveis é lenta e desuniforme, sendo necessário o uso de técnicas que contribuam para acelerar o processo de germinação e uniformizar a emergência em campo. O trabalho teve como objetivo avaliar o efeito de diferentes reguladores vegetais na germinação de sementes de pimenta-tabasco (Capsicum frutescens L.). O delineamento experimental utilizado foi inteiramente casualizado em esquema fatorial 2 x 5 (pré-embebição Print-ISSN 1983-6325 (On line) e-ISSN 1984-7548 Souza et al. (2014) e reguladores vegetais), em quatro repetições de 50 sementes para cada tratamento. Os reguladores vegetais utilizados foram (1) Stimulate ® ;(2) Sett ® ; (3) CaB ® ; (4) Progibb ® , y (5) água destilada, cujas sementes foram pré-embebidas por 24 horas ou postas para germinar diretamente em soluções com os reguladores vegetais. A pré-embebição promoveu maior percentual de germinação, de plântulas normais e crescimento de plântulas de pimenta tabasco, independente da solução. O uso dos reguladores vegetais Progibb ® e Stimulate ® estimula a germinação de sementes e crescimento inicial de plântulas de pimenta-tabasco e a utilização de qualquer um dos biorreguladores avaliados estimulou o desenvolvimento de raízes.Palavras-chave: Capsicum frutescens; embebição; reguladores de crescimento

“…The use of micronutrient enriched seeds (seed priming) has been reported to be an easier and cost-effective strategy in overcoming micronutrient deficiencies (Harris et al, 1999;Rakshit et al, 2013). Seed priming has been shown to enhance the speed of germination (Deering & Young, 2006), reduce the emergence time, enhance seedling vigour (Harris, 1996) and obtain better stand establishment (Diniz et al, 2009), and increase yield (Yilmaz et al, 1998) in wheat, rice, maize, sorghum, chickpea, and soybean. There is evidence that sowing seeds enriched with micronutrients is also agronomically beneficial (Welch, 1986).…”

<p>Priming techniques are gaining importance in agriculture with the increase in environmental stresses. Resource-poor farmers are in urgent need of such techniques as they are simple, economical, and value-added intervention associated with low-risk bearing factors. Seed enhancement methods are key to improve seed performance and achieve a good stand establishment. Worldwide beneficial effects of priming are recorded. But these technologies have still not reached most farmers. This review highlights the importance of on-farm priming strategies in modern crop production system to yield better productivity and obtain higher economic returns. Stimulation of the pre-germination metabolic changes by priming is necessary to overcome the environmental challenges that a plant can encounter. Thus, the study also focuses on mechanisms associated with priming-induced stress tolerance of crops. Various safe practical methods of seed priming can be easily adopted by the farming community to alleviate the levels of different stresses which can hamper productivity. Simultaneously they can produce good quality seeds and use them further for the next crop cycle cutting the costs of seed purchase.</p>
