EFFECT OF RESIDUAL EFFECTIVE ALKALI ON EUCALYPTUS KRAFT PULP YIELD AND CHEMISTRY [PDF]

CERNE, 2018
ABSTRACT The impact of residual effective alkali (REA) and pulp delignification degree on Eucalyptus kraft pulp yield and chemistry was investigated. In this study four types of eucalypt clones were evaluated. The eucalypt woods were cooked to kappa numbers of 14±1, 18±1, 22±1 and 26±1 using two different ranges of REA, namely: low-REA (1-2 g.L-1) and ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...
