The Effect of Polyploidy Induction on Some Growth Parameters in 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 significant increase in soluble carbohydrate، reducing sugar، starch and protein content in comparison to diploids and tetraploids. However، tetraploids had higher amount of starch and protein in compare with the diploid plants. On the other hand، cellulose، soluble and reducing sugars content، in tetraploids were lower than diploids. The total protein profiles of plants with different ploidy levels، revealed qualitative and quantitative changes. As a result، ploidy induction in addition to morphological effects has an effect on biochemical traits.
