Phenotypic and genotypic evaluation of Parkia platycephala families: a proposal for pre-selection

نویسندگان

چکیده

The objective of the study was to determine whether Parkia platycephala families with superior morphophysiological traits perform consistently across four stages early development (plantlets, seedlings, and juveniles at 34 60 months), as a means assess possibility conducting pre-selection. For 21 traits, following genetic parameters were estimated: heritability, coefficients variation (genetic, relative, environmental), accuracy, phenotypic correlation, percentage coincidence (PC) best families, effective population size, inbreeding in three progeny tests conducted under laboratory, nursery, field conditions. Families P. showed significant genotypic differences. evaluated show control. between more accurate when selection intensity greater than 50% (PC ≥ 52%). Based on pre-selection strategy juvenile stage for researched effectively identify families.

Phenotypic and genotypic selection of microbiota surviving under dental restorations.

The effects of sealing infected carious dentine below dental restorations on the phenotypic and genotypic diversity of the surviving microbiota was investigated. It was hypothesized that the microbiota would be subject to nutrient limitation or nutrient simplification, as it would no longer have access to dietary components or salivary secretion for growth. The available nutrients would be limi...

Evaluation of Phenotypic and Genotypic Expression of Efflux Pumpin Clinical Isolates of Acinetobacter baumannii Resistant to Ciprofloxacin and Gentamicin

Introduction: Acinetobacter baumannii is an important bacteria because of high ability to obtain antibiotic resistance genes and creation of multi-drug resistant strains (MDR). Today, the active efflux pumps has been suggested as one of the most important mechanisms of intrinsic and acquired resistance of antibiotics in bacteria. The aim of this study was Evaluation of phenotypic and genotypic ...
