Evaluation of seed priming and coating on germination and early seedling growth of sesame (Sesamum indicum L.) under laboratory condition at Gondar, Ethiopia

Ondas Sonoras Tem Efeito Positivo Na Germinação De Sementes E Produção De Mudas De Hortaliças / Sound Waves Have a Positive Effect on Seed Germination and Seedling Production in Vegetables

“…O efeito do som na aceleração da germinação de sementes e no crescimento de plântulas pode ser devida a elevação dos níveis de fitormônios promotores de crescimento, já que a aplicação do som aumentaria os níveis de hormônios como o ácido giberélico, a citocinina e o etileno, resultando em quebra de dormência e aceleração da germinação (MISHRA et al, 2016;TIZAZU et al, 2019).…”

“…Quando os sinais sonoros são recebidos pelas plantas, eles irão estimular uma resposta por canais sensíveis que fazem parte da constituição de membranas das células (JOSHI et al, 2011;TAIZ et al, 2017). Devido a germinação da semente ser um ponto crítico no desenvolvimento de uma planta e sua ocorrência ter impacto diretamente na continuidade da espécie no ambiente natural e na produtividade, melhorar o estabelecimento dessas plântulas aumentará o seu rendimento (ANOSHEH et al, 2011, TIZAZU et al, 2019. Nesse sentido, a presente revisão de literatura aborda sobre vibrações sonoras ou ondas acústicas com frequências e intensidades específicas aplicadas na germinação de sementes e produção de mudas de hortaliças.…”

Effect of degree of salinity on seed germination and initial growth of chickpea (Cicer arietinum)

“…For example, previous studies devoted to the investigation of sesame (Sesamum indicum L.) seed germination proved that the latter is significantly affected by different seed treatments used in the trials. It was determined that the best option of getting healthy sprouts of the crop with high germination percentage (91.5%) is treatment of the seeds with freshwater (Tizazu et al, 2019).…”

Effect of Phosphorus Fertilizer Rates and Seed Priming Treatments on Seed Quality of Bambara Groundnut

“…Germination commenced earlier in all hydropriming durations than the control, this agrees with Berchie et al (2010) who reported that Bambara groundnut seeds hydroprimed for 24 and 48 hours emerged earlier than nonprimed seeds under field conditions. Hydropriming has been shown to improve seed germination in crop species such as groundnut (Das & Mohanty, 2018), sesame (Tizazu et al 2019), bitter gourd (Tania et al 2019), Aegle marmelos (Singh, 2017), but some studies also reported that germination decreases with increased priming duration (Kumarimanimuthu & Kalaimathi, 2019;Ogbuehi et al 2013;Dastanpoor et al 2013). Very low percentage emergence (5.7%) and no emergence at all was observed with 48hours, and 72 hours hydropriming durations respectively in comparison with the control (35.7%) in groundnut seeds (Kumarimanimuthu & Kalaimathi, 2019).…”

“…Hydropriming also antagonizes the functions of Trypsin-like proteolytic enzymes inhibitors present in some seeds (Ashraf & Foolad, 2005). Hydropriming has been reported to improve germination capacity in tomato, groundnut and sesame (Camu, 2017;Das & Mohanty, 2018;Tizazu et al 2019). On the other hand, seed priming with potassium nitrate also improves seed germination by + osmotic activity of potassium ions (K ) that helps in cell water standing, and acting as cofactor for some metabolic enzymes, and nitrate ions which acts as a substrate for amino acid and protein synthesis (Taiz & Zeiger, 2010).…”
