Divergence and variation of quantitative traits between allozyme genotypes of Avena barbata from contrasting habitats
1 Avena barbata occurs as two multilocus allozyme genotypes associated with moist (mesic) and dry (xeric) habitats in California. We examined the divergence of quantitative traits between these genotypes, and heritable trait variation in the progeny of a cross. 2 A replacement series showed that the mesic genotype was competitively superior to the xeric. Early germination could alter this compe...
متن کاملEvolution of multilocus genetic structure in Avena hirtula and Avena barbata.
Avena barbata, an autotetraploid grass, is much more widely adapted than Avena hirtula, its diploid ancestor. We have determined the 14-locus genotype of 754 diploid and 4751 tetraploid plants from 10 and 50 Spanish sites, respectively. Allelic diversity is much greater in the tetraploid (52 alleles) than in the diploid (38 alleles): the extra alleles of the tetraploid were present in nonsegreg...

The objective of this study was to investigate aspartate-amino-transferase (AST), γ-glutamyl-transferase(GGT), alkaline phosphatase (ALP), lactate-dehydrogenase (LDH) and acid phosphatase (AcP) activities andsemen parameters (volume, pH, concentration, total sperm number (TSN), progressive motility, dead sperm,total morphological defect (TMD) and hypo-osmotic swelling test (HOST)) in seminal pl...
متن کاملDifference Between any Morphological and Physiological Characters of three Sugar Beet Genotypes in Different Irrigation Treatments
The aim of this study was to investigate the effect of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named BP Mashhad, BP Karaj and 191. The experiment was in a split plot based on randomized complete block design , carried out at Motahari Research station of Sugar beet Seed Research Institute ...
