摘要

Rhododendrons form a major plant group at upper temperate locations having a characteristic slow growth rate and sizable horticultural value. Asia is the homeland for rhododendrons and many species had been hunted out of the region during British rule. About 98% of the Indian species are found in the Himalayan region, among which 72% are found in Sikkim. Due to human interference the natural populations of rhododendrons in the entire Himalaya are gradually diminishing. The major threats to rhododendrons are deforestation and unsustainable extraction for firewood and incense by local people. A set of rhododendrons which are classified as rare/endangered may be wiped out from the biota in the near future if proper conservation measures are not made. The present work incorporates biotechnological and conventional methods to counter the threat on survival of these plants. Studies on in vitro Rhododendron maddeni from the cotyledonary nodal segments, young leaves and stems, have yielded positive results. The goal of the work is to find out means of conservation through in vitro and ex situ mass propagation and restoration of rhododendron population in the wild.
