Reproductive abilities in induced autotetraploids of Datura stramonium L. and Hyoscyamus niger L. (Solanaceae)



Reproductive abilities in induced autotetraploids of Datura stramonium L. and Hyoscyamus niger L. (Solanaceae)



Phytologia Balcanica 7(1): 147-151



A comparative investigation of the reproductive abilities of diploids and induced autotetraploids of Datura stramonium L. and Hyoscyamus niger L. is presented. The tetraploid forms had lower pollen fertility and seed formation than diploids. Germination capacity of the tetraploid seeds was slightly lower too. The seeds of tetraploid forms had also later germination and germination maximum, as well as a longer germination period.
