Chromosome studies in the genus Pterotricha (Gnaphosidae) from Turkey

Diversity of chromosome numbers and meiotic studies in genus Anchusa (Boraginaceae) from Iran (10 Nov 2015)

The present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of Anchusa subgenus Buglossum Gusul. from Iran. All populationsshowed the chromosome number 2n= 4x= 32. It is the first meiotic study for A. subg.Buglossum. We discuss some habit form and evolutionary aspect in the light of cytogeneticdata. The origin of polyploidy (auto-allopolyploidy)...

Chromosome studies in the genus Jatropha L

The inflorescences of ten species of the genus Jatropha were fixed in Cornoy’s fluid (6:3:1). Acetocarmine stain (2%) was used for staining the pollen mother cells. Seven species exhibited 11 bivalents and 2n =22 and x=11. But the two other species, J.villosa var. villosa and J.villosa var. ramnadensis showed only 10 bivalents and 2n number of 20 chromosomes and x=10. The study concluded the oc...
