Farmed Atlantic cod Gadus morhua have been hypothesized to pose a risk to the natural environment through escape of fish or release of their gametes from sea cages. The use of sterile triploids has been suggested as a way to prevent spawning of farmed fish, whether escaped from their cages or still contained within them. This laboratory study examined the reproductive potential of triploid male...

Safflower (Carthamus tinctorius L.) is one of the important oilseed and bio-energy crops. All safflower cultivars in world have diploid genomes (2n= 2x= 24). In this research, autotetraploidy induction was performed by colchicine treatments to emerging shoot tips at cotyledonary stage. As a result flow cytometric analyses C2 progenies, autotetraploids (4x= 48) had DNA content 4.88 pg 2C-1, whil...

Abstract The grass Deschampsia cespitosa is a variable taxon out of which many varieties, subspecies and endemic species have been separated. In this paper, the variation in genome size (GS) ploidy including several its two related Eurasia was investigated by flow cytometric (FCM) measurements. GS data were also to specific environments reproduction mode. Ploidy levels found FCM confirmed chrom...

Polyploidization is an important technique used in grape breeding to create new genetic resources and can be induced using some antimitotic agents, including colchicine. Plants with increased ploidy gain better quality than their original diploids characteristics. In this study, which was carried out obtain polyploid genotypes under vivo conditions, the effects of six (1 g L-1, 2 3 4 5 6 L-1) d...
