http://indexmedicus.afro.who.int Evaluation de l'introgression du caractère croissance lente de quelques géniteurs Akpadanou (origine Bénin) chez quelques géniteurs améliorés de palmier à huile (E. guineensis Jacq.) de l'origine La Mé (Côte d'Ivoire)

Effet du sel sur le comportement des jeunes plants de palmier à huile (Elaeis guineensis Jacq.) en Basse Casamance

“…En effet, les valeurs obtenues ont varié de 19,86 à 35,89 cm/an au sein de ces descendances testées, contre 45,25 cm/an pour le témoin de l'essai. Une réduction de plus de 20% de la vitesse de croissance en hauteur a donc été observée au niveau de ces descendances (Konan et al, 2014).…”

Oil palm (Elaeis guineensis Jacq.) genetic differences in mineral nutrition: potassium and magnesium effects on morphological characteristics of four oil palm progenies in Nigeria (West Africa)

“…The oil palm progenies tested in our study originate from breeding programs aiming at developing more compact planting material (i.e. with shorter internodes; Durand-Gasselin et al, 2000;Cochard et al, 2005;Konan et al, 2014). Above 13 m in height, oil palms are no longer economically viable because of increased cost of harvest (fruit bunches in tall palms are more difficult to harvest; Cochard et al, 2001;Konan et al, 2014).…”

“…Oil palm productivity has been continuously improved (Durand-Gasselin et al, 2000;Rival and Levang, 2010) by crossing different oil palm genotypes with useful traits such as fresh fruit bunch (FFB) yield, mesocarp thickness and consequently shell thinness (Cochard et al, 2001;Durand-Gasselin et al, 2006;Durand-Gasselin et al, 2011;Junaidah et al, 2011;Corley and Tinker, 2016). Oil productivity over the lifespan of the oil palm is determined using several different factors, among which researchers have focused particularly on slow trunk growth rates to extend the economic life of the palm (Baudouin et al, 1997;Tailliez and Koffi, 1992;Durand-Gasselin et al, 2009;Verheye, 2010;Bonneau et al, 2014;Bonneau et al, 2017;Konan et al, 2014;Fan et al, 2015;Corley and Tinker, 2016). The trunk growth rate varies between 25 and 65 cm per year (Cochard et al, 2001;Konan et al, 2014), depending on environmental and genetic factors (Cochard et al, 2005;Verheye, 2010).…”

It has been shown that growth characteristics vary according to oil palm genetic origins (Nouy et al, 1999;Konan et al, 2014;Corley and Tinker, 2016).…”

It has been shown that growth characteristics vary according to oil palm genetic origins (Nouy et al, 1999;Konan et al, 2014;Corley and Tinker, 2016). We consequently assumed that this would also be the case for four selected progenies with different genetic backgrounds (Tab.…”
