Multiple Shoot-Bud Stimulation and Rhizogenesis Induction of Embryogenic and Juvenile Explants of Walnut

Somatic Embryogenesis and Synthetic Seed I

“…It is important to call attention to earlier work on zygotic embryos of walnut by Cossio and Minotta (1983), Rodriguez and Sanchez-Tames (1981), and Rodriguez (1982), as well related recent publications by Jay-Allemand and Cornu (1986), Penuela et al (1988), Rodriquez et al (1989, and the work on apomixis in walnut by Deryuzhkin et al (1985). These studies contribute to the general advance of our understanding of walnut embryogenic development.…”

Problemas de oxidación y oscurecimiento de explantes cultivados in vitro

“…esto se puede lograr mediante: Pretratamientos en especies que generan exudados con efectos perjudiciales, la implementación de un pretratamiento aplicado al explante puede ser de mucha utilidad. Por ejemplo, Pérez et al (1985) y Peñuela et al (1988) mencionan la utilidad de aplicar un baño de agua continua durante 16 a 24 horas para la remoción de sustancias fenólicas producidas en semillas de Corylus sp. y Juglans sp., respectivamente, antes de su desinfección.…”

Effect of Different Hormonal Treatments on Proliferation and Rooting of Three Persian Walnut (Juglans regia L.) Genotypes

“…The DKW medium known to reach to this target. Moreover, different concentrations of BAP, IBA and BA found to be stimulant to increase the walnut vegetative buds induction, propagation and rooting (Saadat and Hennerty, 2002;Driver and Kuniyuki, 1984;Penuela et al, 1988;Amiri, 2005;Jay-Allemand et al, 1992;Tetsumura et al, 2002;Sanchez-Zamora et al, 2006). In recent years, the walnut micro propagation methods are highly developed but successful shoot and root developments still in demand to commercialize the protocol.…”
