Variations in Achene Traits, Germination and Seedling Growth of Pluchea dioscoridis (L.) DC. As affected by Maternal Climatic Aridity

Abstract

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ interest on the effect of such events on plant life cycle starting from seed viability and germination to plant fitness (Münzbergová et al., 2017;Alshoaibi, 2021). On the other hand, several plants lose a few of their seeds, seedlings, or individuals (Funkenberg et al., 2012); others display adaptive plasticity under climatic changes (Mclean et al., 2014). Long day length and photoperiod during seed development of the maternal plant environment have been associated with high seed dormancy and low germinability (Baskin & Baskin, 1998;Gutterman, 2000). Several studies recorded changes in the reproductive traits and resource allocations of numerous species in response to climate changes (Hegazy, 2000
