Adsorption of a cationic dye by Marula (Sclerocarya birrea) fruit seed shell based biosorbent: Equilibrium and kinetic studies

Adsorption of methylene blue from aqueous solution using a low cost Sclerocarya birrea fruit shell powder based biosorbent was investigated in a batch system. Results showed that optimum adsorption capacity was achieved at pH 8 and biosorbent dosage of 0.6 g, with a maximum adsorption capacity of 27.690 mg g-1. Equilibrium studies showed that experimental data fitted well on the Temkin isotherm (R2 = 0.9641), as well as...

The effects of plant growth regulators on in vitro gynogenic embryo formation in onion (Allium cepa L.)

Different combinations of plant growth regulators were tried on in vitro gynogenesis by flower bud and ovary culture for two open pollinated Turkish onion cultivars, “Bayram 1” and “Yakut” and a synthetic population of “OH-1”, which serves as a responsive control for extraction of gynogenic haploids of onion for two years (2011 and 2012). In 2011, modified Dunstan and Short (BDS)...

Selection of loose-leaf lettuce breeding lines based on non-parametric indexes

Non-parametric selection indexes (that is, require no estimation of parameters) can be used to help the selection process in the final stage of genetic enhancement. In this context, the objective of this study was to evaluate the efficiency of non-parametric selection indexes to choose promising lineages of loose-leaf lettuce, so that genetic gain of each lineage can be estimated and then registered in the Ministry of...
