The medicinal properties of Gloriosa superba, a perennial herb reproducing both by seed and tuber, are due to presence of colchicine in its seeds and tubers. The weak stemmed aerial part is annual which dries off after setting seed. Harvesting its tubers for medicament leads to destructive harvesting. Using seeds for drug purposes (with higher colchicines content as compared to tuber) has the advantage of annual harvest and also avoiding destructive harvesting. However, seed production under natural condition is quite low and uneconomical. It has been found that seed setting in the species is pollen limited. Results obtained have revealed that although the species is both self as well as cross compatible but seed setting is significantly influenced by pollination methods used. Controlled selfing between different flowers on the same plant have given significantly higher seed setting as compared to other methods tried. There was considerable increase in number of seeds produced per capsule (42.26) and dry seed weight per plant (1.13 g). It is suggested that for increasing seed set different flowers on the same plant should be selfed (Gnetonogamy) at stigma receptive stage.Keywords

Effect of different concentrations and dipping time periods of growth regulators IAA, IBA, NAA and GA3 on ischolar_maining, field survival and ischolar_mainstock biomass yield in important endangered alpine medicinal plant Picrorhiza kurroa revealed that pre-planting treatments of stolon cuttings by IBA 100ppm for 24 hrs resulted in maximum sprouting percentage (88.89 %), field survival (77.18 %) and dry ischolar_main-stock (economic part) biomass yield of 7.8 g/plant after two years. Treated cuttings can be directly field planted which can reduce the cost. An estimated yield of approximately 577 kg of dry ischolar_mainstock per hectare can be obtained after two years of field growth.- Scope of Re-incorporation of Selected Medicinal Plants in Forest Ecosystems

Approach to conserve biodiversity for sustainable development should be targetted at different levels, from improving living standards to changing the attitude of people. If Himalayan medicinal plants are to continue to serve the needs of the people without being reduced to a dangerously unstable resource base, they have to be considered in the perspective of sound ecological management that also has economic benefits to the local people. From the concept of in-situ conservation we need to move to In-situ cultivation.Keywords

Mucuna pruriens, commonly known as Konch or Cowhedge is a traditionally used medicinal plant. Seeds of the species contain high percentage of active principle L-DOPA, which is used for curing Parkinson disease. There is a great variation in the seed colour of the species, and in the present study twenty eight black mottled with brown (collected locally) and creamish white (procured form NBPGR New Delhi) seeds were evaluated for morphological parameters as well as for L-DOPA content. Black seeded collections were found to contain high level of L-DOPA ranging 6.36 to 7.30. But, the seed yield and consequently L-DOPA yield was low ranging 38.40-65.86g and 2.35-4.69g per plant respectively Moreover, pods of these collections contain itching trichomes which puts workers in commercial cultivation Among black seeded collections regarding seed yield, L-DOPA content and L-DOPA yield collections Panba, Nagrota, Jwalaji Hilltop and Jwalaji excelled over all other collections. L-DOPA content in white seeded collections was low ranging 5.41-5.78 per cent. But, the seed yield and consequently L-DOPA yield was very high ranging 4.30-697.20g and 23.38-39.73g respectively. Also, pods of these collections are devoid of itching trichomes. Among white seeded collections regarding seed yield, L-DOPA content L-DOPA yield collection IC127363 and IC 127362 excelled over other collections. Exotic collection EC 144945 performed below par for all the parameters studied.Keywords

The narrowing of diversity in crop species contributing to the world’s food supplies has been considered a potential threat to food security. The present study quantifies crop species diversity in controversial shifting cultivation system (SCS) using primary data from 52 villages spread across six North-Eastern (NE) hill states of India. The findings reveal that SCS is much diversified compared to settled cultivation system. Along with cereals, millets and pulses, the upland tribes grow a variety of horticultural crops on SC land. At the aggregate level, horticultural crops in the sampled states were observed to be much diversified and the mean diversification index value was found to be 0.79 (Simpson’s Diversity Index) for the six NE hill states on SC land. The present study documented 25 cultivars of vegetables, 22 cultivars of fruits, spices and plantation crops, and 12 field crops in SCS, besides many minor fruits and underutilized vegetables. However, the most densely populated crop species were rice, maize and finger millet in the case field crops. Vegetable crops included pumpkin, potato and ash gourd, and fruit crops included banana, pineapple and citrus, while spices like ginger, chilli and turmeric were densely cultivated on SC land. Thus, the prevailing crop species in SCS had their own attributes, performances and challenges. Experiences of the present study shall be the guiding benchmark for those who negate the possibilities of agrobiodiversity in SCS.Keywords
