Seed length and seed width are an important factor to the soybean yield. So the quantitative trait loci (QTL) location for seed length and seed width could assistant the breeding of soybean. In this study, the QTL underlying seed length and seed width were studied. A recombinant inbred line population of soybeans derived from a cross between the American semi-draft cultivars Charleston and Dong...
The aim of this study was to enumerate the bacterial population isolated from environmental surfaces in child-care centres Omoku and Port Harcourt, Nigeria. Four Nigeria were selected for samples different (Table, play mat, toilet seat, feeding area, diaper changing toys, window door handle surfaces) using sterile swab sticks moistened with peptone water. Aliquots 0.1 ml 103 dilutions inoculate...
The seed coat is involved in the determination of seed quality traits such as seed size, seed composition, seed permeability, and hormonal regulation. Understanding seed coat structure is therefore a prerequisite to deciphering the genetic mechanisms that govern seed coat functions. By combining histological and transcriptomic data analyses, cellular and molecular events occurring during Medica...
From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms. The purpose of this paper is to examine feeding constraints, morphological adaptations, and the...
1 We present results from a long-term sowing experiment conducted in nutrient-poor savanna grassland in eastern Minnesota. We examine the effects of a one-time seed addition of 23 grassland species on plant community dynamics and structure over eight growing seasons. 2 Our goals were to: (i) test the importance of seed availability in regulating plant colonization dynamics and species richness;...
Agents responsible for tosses of conifer seed and methods for seed protection are reviewed. Published information indicates that much seed is destroyed, especially by seedeating rodents and birds. Improvement of existing protective methods and development of new chemical means are necessary to overcome the problem.
This paper considers strengths and weaknesses of the informal and formal seed as a basis for seed sector development. The informal seed sector is defined as the total of farmers’ seed production, selection and seed exchange activities. Farmers play an important role in seed supply but they are generally not considered as a partner in the seed sector. Seed produced by farmers is still the most i...
OBJECTIVES This paper reports on the results of the study aimed at application of ergosterol as an quantitative indicator of fungal bioaerosol present in the indoor air in occupational environment heavily contaminated with organic dust as well as its comparison with the culturable method. MATERIAL AND METHODS The study was conducted in the indoor solid waste sorting plant. Using Andersen impa...
To provide optimum protection against classical and El Tor biotypes of Vibrio cholerae O1, a single-dose, oral cholera vaccine was developed by combining two live, attenuated vaccine strains, CVD 103-HgR (classical, Inaba) and CVD 111 (El Tor, Ogawa). The vaccines were formulated in a double-chamber sachet; one chamber contained lyophilized bacteria, and the other contained buffer. A total of 1...
