Effects of exogenous application of five antioxidants on vigour, viability, oxidative metabolism and germination enzymes in aged cabbage and lettuce seeds
(Elsevier B.V., 2021)Ageing induces modifications capable of compromising seed vigour and viability. This study investigated the effects of exogenous application of five antioxidants: ascorbic acid (AA), gallic acid (GA), reduced glutathione ... -
The effects of family conflict on the psychological needs and externalising behaviour of preadolescents
(SUN, 2018)Families play an important role in the development of individuals. The experiences that occur in the family can either promote or hinder the development of its members. This study aimed to determine the effects of family ... -
The effects of family conflict on the psychological needs and externalising behaviour of preadolescents
(University of Stellenbosch, 2018)Usually, it is within families that we discover, develop and grow as individuals (Corey, 2009; Department of Social Development, 2013). Yet not all families provide an environment that allows for healthy discovery, development ... -
