Abstract

Cassia tora seeds were subjected to four different pre-treatments and different incubation temperatures. Seeds treated with conc. sulphuric acid were found to be best of the pretreatments. Increase in speed and capacity of seed germination was achieved by incubating seeds at higher temperature in comparison to lower temperatures.

Abstract

A study was undertaken to estimate the structure of variation in cone and seed traits of Pinus roxburghii through three-level nested (hierarchical) classification model. The populations studied constituted a continuous stretch of this species. Between-population variation for the cone and seed characteristics was found to be very small as it ranged from 0 per cent to 26 per cent, depending upon the trait. The remaining 74 per cent or more of the variation in these characters was due to the between-tree within-population and the within-tree components. The study showed that if seed collectors are interested in cones of greater weight or length, they should search for trees possessing such cone or seed characteristics within their own planting region, rather than trying to find specific populations for such characteristics outside their planting region, because much of the variation in these traits is accounted for by differences between trees, rather than between populations. Else, they should search for desired stands in distantly located populations or in populations separated by some geographic barrier.

Abstract

Joint Forest Management or Participatory Forest Management (PFM) got its formal shape in the year 1990. A need has arisen to evaluate the impact of this new management tool. A study was taken up in Kodsi and Talaichittor villages of Dehra Dun District to assess the impact of PFM on the socio-economic development of rural people and to identify the prime ingredients of PFM programme responsible for bringing about the desired changes. It was observed that the household income has considerably increased due to alternative job opportunities, agricultural production has increased, there is reduction in distance travelled and time spent for fuel wood and fodder collection, village women are now financially empowered, and institution building has paved the way for sustainability of the whole process.
