Karyomorphological studies in four species of Anemone.

Karyomorphological Characterization of Some Wild Species of Solanum

North East India is one of the mega biodiversity hot spot, also one of the richest reservoir of genetic variability and diversity of different crops. Here, natural distribution of non tuberous Solanum species is also found to be very rich. Despite the importance of Solanum species no information in the karyotype of the members of this taxa available in North East India is found. In the present ...

Cytomorphological Studies in Dugesia Species of Iran

Investigation of Cytotoxic Activity in Four Stachys Species from Iran

   The aerial parts of Stachys laxa Boiss. and Buhse.from Siah-bishe in Mazandaran province, Stachys trinervis Aitch. and Hemsl. from Karaj in Alborz province, Stachys subaphylla Rech. F. and Stachys turcomanica Trautv. from Golestan province have been collected in May 2008. Total extracts were obtained through MeOH/H2O (80/20) and then partitioned between CHCl3, EtOAc and MeOH. These fractions...

Cytogenetic studies in four cultivated Amaranthus (Amaranthaceae) species

In the present study, the chromosomes numbers were confirmed, 2n = 34 for Amaranthus cruentus Linnaeus, 1759, and 2n = 32 for Amaranthus hypochondriacus Linnaeus, 1753, Amaranthus mantegazzianus Passer, 1864, and Amaranthus caudatus Linnaeus, 1753. The distribution and variability of constitutive heterochromatin were detailed using DAPI-CMA3 banding technique. The position of the nucleolus orga...
