Contrasting effects of ploidy level on seed production in a diploid–tetraploid system
Previous studies demonstrated the effects of polyploidy on various aspects of plant life. It is, however, difficult to determine which plant characteristics are responsible for fitness differences between cytotypes. We assessed the relationship between polyploidy and seed production. To separate the effects of flowering phenology, flower head size and herbivores from other possible causes, we c...

متن کاملMeiotic analysis of the hybrids between cultivated and synthetic tetraploid groundnuts
Groundnut is susceptible to a range of diseases and pests owing to its narrow genetic base. Closely related wild relatives of groundnut are diploid, and crossability between diploid wild relatives and tetraploid cultivated groundnut is difficult. Amphidiploid and autotetraploid groundnuts, which are tetraploids (also called synthetic groundnut), were developed at ICRISAT. Crossability between c...
متن کاملاثر القای پلی پلوئیدی بر برخی از پارامتر های رشد در گیاه شاهدانه (Cannabis sativa L.)
In this study, Cannabis plants with different ploidy levels were compared in some growth and biochemical parameters. Tetraploid and mixoploid plants were achieved from previous experiment. Flow cytometry analysis was used to confirm the ploidy level. As a result, root and shoot fresh weight showed a significant increase in tetraploid plants compared to the diploid ones. Chimers showed a sig...
متن کاملGenome duplication and the evolution of conspecific pollen precedence.
Conspecific pollen precedence can be a strong reproductive barrier between polyploid and diploid species, but the role of genome multiplication in the evolution of this barrier has not been investigated. Here, we examine the direct effect of genome duplication on the evolution of pollen siring success in tetraploid Chamerion angustifolium. To separate the effects of genome duplication from sele...
