Germination and initial growth of cowpea cultivars under salinity stress
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 2
Abstract
The use of varieties tolerant to salinity stress conditions has been essential for the crops establishment in are asthat experience with this problem. The aim of this study was to evaluate the germination process and early growth of seedlings of four varieties of cowpea under different levels of salinity. The seeds of BRS Tapaihum, BRS Pujante, BRS Acauã and BRS Marataoã were sown in foam, arranged in tray sand watered with the following NaCl concentrations: 0,50, 100, 150 and 200mM. The analized variables were Percentage of Germination, Emergence Speed Index, mean time, Relative Germination frequency, shoot length and water content of seedling. The cowpea varieties showed loss of germination capacity from 50 mM NaCl concentration. It was also verified that the salinity incidence promoted a decrease of the speed with which the varieties realized their biochemical, physiological, morphogenic events necessary to the process of germination and formation of the new plants.
