Info

The seeds germinate before the onset of the monsoon. The plant grows profusely in the rainy season, and mature seeds are formed in October- November, Due to its sticky nature, the plant gets stuck on the clothes of human beings and on the legs of animals, which helps in its dispersal from one place to another. Some workers have studied the regeneration of this plant through tissue culture. It was reported induction of adventitious shoots using stem explants of B. diffusa. Roots were also regenerated from the leaf segments of B. diffusa when cultured in vitro. These roots contained 0.15% alkaloid punarnavine. Increase in levels of indole-acetic acid (IAA) in MS medium reduced the number of roots regenerated from the leaf segment, their length and alkaloid content. 5.1. Seed propagation Little propagation information is available on this species but suggests sowing the seed in a greenhouse in the spring. When seedling are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Seed sown directly into the beds or poly bags in May-June, Germination completes in 6 to7 days, with 70 to 90 per cent or germination. The cardinal feature of modern cultivation of any plant with impressive uniformity and high productivity for end product is thus grossly lacking in B. diffusa. The need, therefore, is to genetically improve the available commercial bulk of B. diffusa in order to meet the natural requirement of the valuable products. Improved varieties with enhanced drug yields hold great promise. Mutation breeding may have an important role in this direction and may improve the yield and qyality. Recently, it is reported that a substantial amount of genetic variability in B.diffusa. Of the genotypes tested, only a few were elite lines and were found to have desirable material for commercial use. Therefore, commercial manufacture of active constituents from these improved elite lines would be useful and profitable. 6 Commercial Uses 13
6.1. Medicinal uses Parts used are roots, leaves and seeds. According to Ayurveda, Punarnava is bitter, cooling, astringent to bowels, useful in biliousness, blood impurities, leucorrhoea, anaemia, inflammations, heart diseases, asthma, etc. The leaves are useful in dyspepsia, tumours, spleen enlargement, and abdominal pains. According to Unani system of medicine, the leaves are appetizing, alexiteric and useful in opthalmia and in joint pains. Seeds are tonic, expectorant, carminative, useful in lumbago and scabies. The seeds are consklered as promising blood purifier. The roots are diuretic, emetic, expectorant, laxative and stomachic. They are used in the treatment of asthma, oedema, anaemia, jaundice, ascites, anasarca, scanty urine and internal inflammation. The are also said to be an antidote to snake poisoning. An alkaloid in the roots has been shown experimentally to produce a distinct and persistent rise in blood pressure and marked diuresis. 6.2. Other Uses Most if not all members of this genus have the same edible uses. The entire plant including the roots is eaten as vegetable, in curries and soups. The roots and seeds are added to cereals, pancakes, and other foodstuffs. They are also served as bird feed or poultry feed. The plants are grazed by sheep, goats, and cows, and in West Bengal. It is believed that the plant enhances lactation period and also the amount of milk in cattle (CSIR,1988). Leaves can be cooked, root can be baked. Roots are rich in carbohydrate and protein, though the flavour is bland and the texture sometimes woody. It can be ground into a powder and added to cereals when making bread, cakes etc. Reference Bhansali, R.R., A. Kumar & H.C.
