Karyomorphological Studies of Two Morphotypes of Lasia spinosa (Lour.) Thwaites Avaiable in Assam, India

Puspita Hore, Bhaben Tanti*

Abstract


Lasia spinosa belongs to the Araceae family is one of the important medicinal plants, extensively used in rheumatic pain, stomach ache, cholic etc. It also has anticestodal and antinematodal effects. There are two morphotypes available in Assam, which can be easily distinguished by their colour of inflorescences and leaves types. Karyotypic analysis has been carried out to find out any differences in chromosomal level between these two morphotypes of Lasia spinosa from Assam region. The chromosome number of L. spinosa (mixed form) was found to be 2n = 26 in the somatic cells. The chromosome length varied from 2.31µm - 4.08µm while their volumes ranged from 0.034µm3-3.70µm3. The chromosome number of lamina-dissected form was found to be 2n=24 in the somatic cells. The chromosome length varied from 1.09µm - 4.42µm while their volumes ranged from 0.015µm3-0.40µm3. Our finding is different from the previous cytological report, which might be due to ecological adaptation.
