The morphology and ultrastructure of glandular and non-glandular trichomes of Pteronia incana (Asteraceae)

July 2008

  The electron microscopical investigation of foliar appendages of Pteronia incana(Burm) has shown that there are two types of trichomes. The non-glandular type which consists of two-four cells forms a dense mass of long fibrous hairs, covering the entire surface of plant. The glandular trichome types which are club-oval shape and consist of several glandular cells. The gland cells of the glandular...

Irrigation suitability evaluation and crop yield – An example with Amaranthus cruentus in Southwestern Nigeria

July 2008

  A detailed soil survey of 1.03 hectares of land within University of Ado Ekiti Teaching and Research Farm was carried out to evaluate the suitability of the soils for irrigation agriculture and to examine the influence of three different soil types, water and fertilizer rates on the yield of Amaranthus cruentus. All the soils evaluated were considered not suitable for gravity irrigation but soil A...

Molecular analysis and phenotype characterization of the progeny of two antisense potato plants

June 2008

  Two transgenic potato lines csr2-1 and csr4-8, containing two different antisense constructs, csr2 and csr4, respectively, were crossed to investigate the possibility of achieving double transformants with combined effects of the two antisense transgenes on plant phenotypes and cellulose deposition. Molecular analysis revealed an expected segregation ratio of 1:1:1:1 of the four classes. Phenotype...
