For raising artificial plantations of Calamus tenuis, sowing the whole fruits within ten days of collection in the nursery and tending them for two years before transplanting in the field, gives best results. Application of fertilizers after transplanting has no significant effect either on the growth of plants, numbers of suckers they produced after four years of growth or the survival percentage.- Indian Ginseng

Ginseng is a famous Chinese drug used as Panacea and aphrodisiac by Chinese from time immemorial. The principa1 source of Chinese, American and Japanese Ginseng are the tuberons ischolar_mains of Panax ginseng, P. quinquefolius and P. japonicus respectively. Atleast three species, P. pseudoginseng, P. sikkimensis and P. bipinnaatifida, which are distributed in Eastern Himalaya, are the sources of Indian Ginseng. As the well known medicinal product Sanchi of China, used for treating various ailments including cancer, is prepared from P. pseudnginseng the cultivation of the species should be undertaken in East Himalayan region between 1,000 and 2,000 m of altitude. Indian Ginseng species are endongered and should be protected.- Studies on the Effect of Period of Collection and Storage of Sal (Shorea robusta Gaerin) Seed Kernel and its Oil

The paper describes the results of the experiments conducted on the effect of collection and storage of Sal (shorea robusta Gaertn) seed kernels for a period ranging from 15 to 150 days stored under various condition. The yield and quality of the oil extracted from stored kernels after stipulated periods have been determined for the acid, eater and iodine values the effect of storage on the quality of the sal seed fat stored for one year has also been examined.- Further Studies on Seed Production in Sal (Shorea robusta Gaertn.)

Field data regarding production and collection of sal (Shorea robusta Gaertn.) seed in Dehra Dun forests during the years 1978 and 1979, subsequent to the bumper crop year 1977, have been reported. It is observed that bumper crop year is followed by a poor/lean seed year and then by a good/moderate seed year. The minimum quantities of sal seed available per hectare from young to middle-aged and middle-aged to mature crops for these two years along with the optimum time and period of collection are reported.- Introduction of an Exotic Strain of Valeriana officinalis Linn.

Valeriana officinalis Linn, is the source of true valerian and an essential oil, well known in drug trade for use in medicine and an a perfume. It is in fairly good demand in India but does not appear to be cultivated anywhere in the country on commercial scale. The requirement is, therefore, met through imports for which no figures are avai1able. True valerian oil is one of the very costly essential oils; priced Rs 2000/per kg approximately, which is prohibitive and restricts its free use. Instead, the Inferior Indian valerian from Valeriana jatamansi Jones. syn. V. wallichii DC is used as a substitute. In order, therefore, to meet the country's requirement and to save the foreign exchange, the necessity of cultivating a suitable strain of Valeriana officinalis, was felt. Accordingly, seeds of an exotic strain of V. officinalis (from U.S.S.R.) were procured and trials were undertaken in Chakrata Hills (alt. 2150 m), District Dehra Dun, India. The results of cultivation and exploitation are mentioned. Also, the yields of rhizomes/ischolar_mains ,(valerian) and their oil content alongwith its physico-chemical constants, are given.- Studies on Production and Collection of Sal (Shorea robusta Gaertn.)

The result of the studies made on assesment of production of sal (Shorea robsta Gaertn.) seed in young to middleaged and mature sal forests in Lachhiwala Range of East Dehra Dun Forest Division (U.P.) is reported. It was observed that in bumper seed year (1977), mature trees produced 3668 kg of seed per hectare as compared to 3124 kg per hectare produced by the young to middleaged crops. These yield figures are more than three the figures noted in the literature by earlier workers. The difficulties in the collection of sal seed have been discussed and the strategy for exploitation of this important oilseed has been suggested.- A Note on Method of Propagation of Costus speciosus (Koen.)

The common method of propagation of Costus speciosus (Koen.) Sm. Is by planting rhizome cuttings. Since rhizomes of this species are used for extraction of diosgenin, their use as planting material means loss Of diosgenin. An alternative method of propagating the species by planting saplings raised from sprouted node buds, is reported.- Studies on the Cultivation of Artemisia dracunculus Linn.

Gives details of cultivation, growth and exploitation of Podophyllum hexandrum Royle. Podophyllum hexandrum Royle (N.O. Berberidaceae) is an important pharmacopoeial drug plant. The rhizomes and ischolar_mains of this species are well known in medicine as the source of tbe podopbyllum resin. Which is used as a cholagogue purgative. Recentlyl the resin from the American podophyllum. P. peltaturm Linn., has been found to allect the growth of malignant tumours and it has also been shown to be effective in controlling some skin diseases. It is understood that the Indian species is also useful in the treatment of certain types of cancer.- Optimum Stage of Growth for Harvesting the Leaves of Indian Belladonna Cultivated in the Chakrata Hills

Experiments conducted in the Chakrata Hills have shown that the alkaloidal content of the leaves of Indian Belladonna (Atropa acuminala Royle ex Lindl.) is highest when the flower buds are in the primordial stage and the amount of alkaloids decreases as the development of the flower progresses. The optimum stage of growth for harvesting the leaf drug appears to be the "Advanced Flower-bud Stage".- Studies on the Santonin Content of Artemisia brevifolia Wall. Cultivated in the Chakrata Hills
