Condizione: Hervorragend. Zustand: Hervorragend | Seiten: 56 | Sprache: Englisch | Produktart: Bücher | In order to improve agronomic performance of Fenugreek under salt stress, the present research attempts to apply seed priming technique using NaCl through germination and cultivation tests. During these assays, agronomic and mineral parameters were monitored using saline irrigation to test the tolerance of Fenugreek to salinity. First, we determined the optimal concentration and duration of priming with NaCl; for this reason, Fenugreek seeds were pre-soaked separately in two concentrations of NaCl (4 and 6 g/l) for three duration (12, 24 and 36 h). Results obtained showed that the best combination of pretreatment (concentration and duration) giving the best seed germination is a concentration of 4 g/l and a soaking time of 36 h for NaCl solution. Optimal priming combinations (NaCl: 4 g/l, 36 h) were tested on Fenugreek seeds at different levels of salt stress in laboratory and greenhousse experiments. Results showed that, compared to non-pretreated seeds, seed priming improves germination, growth and yield parameters of Fenugreek. Minerals analyzes showed that plants derived from seeds pretreated with NaCl accumulate more minerals than plants derived from control seeds.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Afin d'améliorer les performances agronomiques du fenugrec soumis à un stress salin, la présente recherche tente d'appliquer une technique de traitement préalable des semences à l'aide de NaCl à travers des tests de germination et de culture. Au cours de ces essais, les paramètres agronomiques et minéraux ont été surveillés à l'aide d'une irrigation saline afin de tester la tolérance du fenugrec à la salinité. Tout d'abord, nous avons déterminé la concentration et la durée optimales du traitement au NaCl ; pour cela, les graines de fenugrec ont été pré-trempées séparément dans deux concentrations de NaCl (4 et 6 g/l) pendant trois durées différentes (12, 24 et 36 heures). Les résultats obtenus ont montré que la meilleure combinaison de prétraitement (concentration et durée) donnant la meilleure germination des graines est une concentration de 4 g/l et un temps de trempage de 36 heures pour la solution de NaCl. Les combinaisons optimales de priming (NaCl: 4 g/l, 36 heures) ont été testées sur des graines de fenugrec à différents niveaux de stress salin dans le cadre d'expériences en laboratoire et en serre. Les résultats ont montré que, par rapport aux graines non prétraitées, le priming améliore les paramètres de germination, de croissance et de rendement du fenugrec. Les analyses minérales ont montré que les plantes issues de graines prétraitées au NaCl accumulent plus de minéraux que les plantes issues de graines témoins.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Al fine di migliorare le prestazioni agronomiche del fieno greco in condizioni di stress salino, la presente ricerca tenta di applicare la tecnica di priming dei semi utilizzando NaCl attraverso test di germinazione e coltivazione. Durante questi test, i parametri agronomici e minerali sono stati monitorati utilizzando l'irrigazione salina per testare la tolleranza del fieno greco alla salinità. In primo luogo, abbiamo determinato la concentrazione e la durata ottimali del priming con NaCl; per questo motivo, i semi di fieno greco sono stati pre-ammollati separatamente in due concentrazioni di NaCl (4 e 6 g/l) per tre durate (12, 24 e 36 ore). I risultati ottenuti hanno mostrato che la migliore combinazione di pretrattamento (concentrazione e durata) che garantisce la migliore germinazione dei semi è una concentrazione di 4 g/l e un tempo di ammollo di 36 ore per la soluzione di NaCl. Le combinazioni ottimali di priming (NaCl: 4 g/l, 36 ore) sono state testate su semi di fieno greco a diversi livelli di stress salino in esperimenti di laboratorio e in serra. I risultati hanno mostrato che, rispetto ai semi non pretrattati, il priming dei semi migliora i parametri di germinazione, crescita e resa del fieno greco. Le analisi minerali hanno mostrato che le piante derivate da semi pretrattati con NaCl accumulano più minerali rispetto alle piante derivate da semi di controllo.…

As combinações ideais de pré-tratamento (NaCl: 4 g/l, 36 h) foram testadas em sementes de feno-grego em diferentes níveis de stress salino em experiências de laboratório e em estufa. Os resultados mostraram que, em comparação com as sementes não pré-tratadas, o priming das sementes melhora os parâmetros de germinação, crescimento e rendimento do feno-grego. As análises minerais mostraram que as plantas derivadas de sementes pré-tratadas com NaCl acumulam mais minerais do que as plantas derivadas de sementes de controlo.…
