Abstract

Nutritional requirements for germination of mature zygotic embryos of four genotypes of Elaeis guineensis Jacq. Dura × Pisifera were assessed. A factorial experiment was conducted with four genotypes from separate crossing events and three culture media to show Interactions between genotypes and culture media on seedling germination (p < 0.05). The highest frequency of normal seedling germination was facilitated by 1/2 Murashige and Skoog (MS) medium (29.2%), followed by MS (15.0%) and Blaydes (12.9%). Speed of shoot formation followed a similar trend. Roots were induced most rapidly in 1/2 MS medium, followed by Blaydes and then MS. Root induction was similar in 1/2 MS medium (2.29%) and Blaydes medium (1.25%) but only significantly higher than in MS (0.00%).

Trichospilus diatraeae (Hymenoptera: Eulophidae): development and reproduction in Lepidoptera palm oil pests

“…is of African origin and the main agro-industrial activity in humid areas in the Brazilian Amazon, Colombia, Ecuador, Malaysia, Indonesia and several African countries (Hansen et al, 2015). This culture is a source of vegetable oil for food production and Bio fuels with high profitability, employment generation fixing the man in the field and reduced environmental impacts (Thawaro and Te-chato, 2010;Abdalla et al, 2008). Elaeis guineensis is well adapted to the Amazon conditions with this region being that with the largest area in the world to expansing activity (Chia et al, 2009).…”
