Genetic Association Among Morphological Traits of Lepidium Draba

Abstract

Lepidium draba is a weed plant usually grown where the conditions are moist like road side, ditch banks, rang lands and pastures. It is a fast growing weed plant that competes with crop plants for water, mineral nutrients, light and plays as a hiding place for insects. The prescribed study was carried out to evaluate morphological traits of Lepidium draba under four different locations. It was found from results that plant fresh weight and moisture contents were relatively higher for under studied locations. There was a strong and significant correlation among fresh weight, dry weight, moisture contents and plant height. From regression analysis it was predicted that plant dry weight and moisture contents played an important role in improving fresh plant weight. GGE biplot showed location 4 as best environmental area for propagation of Lepidium draba. It was suggested from current study that the plant population of Lepidium draba to minimize yield losses in crop plants and reducing competition between Lepidium draba and crop plants.

Different Species of <i>Salmonella spp</i> and <i>Shigella spp</i> and Their Risk of Infection in N’Djamena Chad

“…to gentamicin and 34% to ceftriaxone. These results corroborate those of Mohammedaman et al [20]. Similarly, the level of resistance of Salmonella isolates to chloramphenicol and gentamicin is lower than the results of studies carried out in Harar Qureishi et al in Addis Ababa Wasihun; and Gonder Arora et al [24] [25].…”

“…The prevalence of Salmonella and Shigella species isolated from all stool samples was 4.16%, which does not corroborate the result of Mohammedaman et al, [20] who found a prevalence of 9.2% were positive for Salmonella and Shigella.…”
