“…Ethrel at lower concentration used in this study reduced the flowering time while higher concentration caused delay in flowering. The undesired effect of high concentration of ethrel on flowering of impatiens plants is also reported by Tamari et al (1998).…”

Gladiolus is an ornamental bulbous plant and is commercially propagated in the world through its corms. Usually, a single bud is sprouted from a mother corm but sprouting of multiple buds favors an increase in production of propagules. Thus, present research work was carried out to enhance the sprouting of multiple buds and evaluate its effects on other growth parameters through pre-plant soaking of corms in solution of plant growth regulators. The corms were soaked in solutions of gibberellic acid (GA 3 ), benzyladenine (BA) or ethrel at 0, 50, 100 or 150 ppm concentrations for 24 hrs before planting in the field. Gibberellic acid at 100ppm concentration increased plant height to 105 cm compared to 97.60 cm in control plants, flowering percentage (84.67%), spike length (40.03 cm) and also boosted the corm weight (68.30 g). Soaking of corms in 150 ppm benzyladenine solution enhanced the number of sprouting per corm (2.14) and reduced the plant height (87.00 cm) while 50 ppm concentration of ethrel increased the spike length (42.14 cm). In conclusion, soaking of corms in benzyladenine favored the modifications in various traits of interest including sprouting of multiple buds and an increase in the production of corms while gibberellic acid improved the floral characteristics of gladiolus spikes.

“…PBZ has been found to be predominantly effective in the induction of early flowering and thus finding scope for offseason production in different crops such as mango (Upreti et al, 2013), citrus (Martínez-Fuentes et al, 2013, wheat (Kondhare, Kettlewell, Farrell, Hedden, & Monaghan, 2012;2013;, among others. Ethephon treatment caused a transient increase in ethylene production and inhibited vegetative growth (Tamari, Pappa, Zered, & Borochov, 1998). Moreover, ethylene is known to generally inhibit shoot extension whilst promoting root proliferation (Jaiswal & Sawhney, 2006;Liu, Mukherjee, & Reid, 1990;Pan, Wang, & Tian, 2002) and significantly speeds up senescence (Hodges & Forney, 2000;Philosoph-Hadas, Meir, & Aharoni, 1991).…”

Unas pequeñas notas…A Dios, a través de quién entiendo toda la vida. Él es la causa y motor por la cual he podido realizar el doctorado. Me siento identificada con las palabras que dijo en su momento Alfred North Whitehead (matemático y filósofo inglés):"El hombre fue capaz de hacerse científico porque presuponía ver a Dios en la naturaleza. Y presuponía leyes en la naturaleza porque creía en un dador de leyes".A Joel, mi increíble acompañante con quien formo equipo en el camino de la vida.A mis padres y hermanas, por su cariño, cuidado y ejemplo.A mis directoras, por su apoyo, tesón y convicción de querer sacar lo mejor de mí.A mis compañeros de laboratorio, sobre todo a Mariola y Juan, por los buenos momentos e interesantes conversaciones. Las obras de Dios son grandes, y quienes las aman, las estudian.Salmo 111:2 digestiu, així com l'efecte protector de la matriu (fruit o fibra) enfront de la degradació d'aquests compostos. Cal destacar no obstant açò, que la ingesta d'una infusió (1.5 g en 110 ml d'aigua) de fulla de caqui i d'un fruit de 200 g aportarien al final de la digestió, la mateixa activitat antioxidant total bioaccesible, mentre que el fruit aportaria dues vegades més polifenols bioaccesibles i tres vegades menys flavonoids bioaccesibles que la infusió.
