compare priming techniques for emergence and vigor of parsley’s seedlings, providing an optimal priming strategy for parsley seedling production. Material and methods Imbibition curve of parsley seeds. The first step of this study was to
numerous small, shiny black berries that ripen from mid-September through October. The berries are barely edible, having large seeds, grit-like sclerids, and little juice. Vaccinium arboreum interests blueberry breeders for several reasons. In particular
Farmers throughout the world have traditionally used fire and smoke in grain drying practices. It is thought that these methods improve germination and seedling vigor ( Paasonen et al., 2003 ). Recently, the germination response to smoke has been
