Abstract :

The chlorophyceae (green algal flora) of cultivated rice fields of Jammu district (J&K) was surveyed, the collections were made from different locations like R.S. Pura, Mandal Phallan and Marh of Jammu district. The rice fields of Jammu harbour a very rich flora of green algae, 91 genera 268 species 49 varieties and 14 forms have been reported from the study area. Looking at the diversity of genera and species of algae studied, it has been found that the most dominant genus with regard to the number of species is Cosmarium followed by Spirogyra, Oedogonium and Scenedesmus. Though other genera of algae of greater significance were also present with less number of species but still it is quantitatively better represented. An attempt has been made to study the composition of various algal taxa in two phases. Once when the rice seedlings were transplanted in the fields and second the samples were collected when the rice crop was ready for the harvest and the fields still possessed a sufficient quantity of water and the soil was wet enough.
