✦ Synopsis

Populations of Meconopsis paniculara and M. sinuafa inhabit open alpine slopes, while those of M. simplicifolia are restricted to alpine meadows of Sikkim Himalaya. These species are threatened and represented by very small populations. Three enzymes namely acid phosphatase, esterase, and glutamate dehydrogenase were tested for six populations each of M. paniculata and M. simplicifalia and single population of M. sinuata to analyse the genetic diversity of these species. In addition, alkaline phosphatases, glucose 6-phosphate dehydrogenase and malate dehydrogenase were tested for M. paniculata populations. The results on the electrophoretic variations revealed that genetic polymorphism is low to absent in all the populations of the three species of Meconopsis investigated, and the species are characterized by genetic homogeneity with fixed alleles.
