Attempts have been made to provides comprehensive information on the distribution pattern, nativity, classification, cultivation practices and uses of some important medicinal plants of India.  The distribution pattern of the species plays an important role for prioritization of the species for cultivation and conservation.  It has been noted that cultivation of medicinal plants within the distribution range has received greater success than the cultivation of species outside the distribution range.  India has rich diversity in medicinal plants, which needs to be exploited judiciously without disturbing its ecological balance.  Undoubtedly, resources need to be harnessed for economic development but simultaneously we have to be concerned about their regeneration, preservation and propagation, so what these are available to us for use on a sustainable basis.

Productivity improvement of edible bamboo shoot of existing plantation of Bambosa balcooa was assessed over three years in homestead of fringe villages of Hollongapar Gibbon Wildlife Sanctuary, Assam. Edible shoots are harvested from first week of June to first week of September every year for consumption. Shoot emergence was recorded significantly high in treatment T₂ during 2^nd and 3^rd year of the study. More or less same value was observed in shoot length and shoot weight in treatment T₂ and T₃. Application of fertilizer considerably increases nutrient status of soil. However, the percentage of organic carbon, total nitrogen available phosphorus and exchangeable potassium found significantly high during 2^nd and 3^rd year of study. At the harvesting stage less value of nutrient was recorded due to absorption by sprouted clums. Observation reveals that T₂ is the best combination of NPK and plying vermicompost that improves growth of shoot and clum production significantly.

The present investigation on effect of organic manures, Azotobacter and spacing on yield of Solanum nigrum L. was carried out. Seven different treatments with three spacings were studied to observe the impact of these treatments on yield parameters. Overall, treatment of Vermicompost + Azotobacter combination at S₃ (45x45 cm) spacing gave maximum seed yield/plant, fresh above ground biomass per plant, fresh root biomass per plant, dry above ground biomass per plant, dry root biomass per plant as compared to other treatments at different spacings. Maximum value for yield parameters viz. total fresh biomass yield and total dry biomass yield/ha were recorded in treatment of Vermicompost + Azotobacter combination at with 30 x 30 cm spacing. The yield decreased with the further increase in spacing.

Woods of Albizia richardiana has been studied for assessing the suitability for plywood and particleboard manufacture. It was found that 1.5 mm thick smooth and figured veneer can be peeled and dried easily. Three-ply plywood were made using veneer of this species bonded with liquid urea formaldehyde glue of 50% solid content extended with wheat flour and catalyzed (ammonium chloride) with 2% hardener under the three specific pressures, viz,1.05 N/mm²,  1.40 N/mm², 1.76 N/mm² in three replications at 6 minute press time and 120^°C press temperature. Dry and wet shear test were conducted on the sample and their shear load at failure per unit area and percentage of wood failure were determined. 1.05 N/mm² pressure for the manufacture of plywood was found to be the best. The physical and mechanical properties of Albizia richardiana wood particleboard were studied. The particleboards were tested for determining the strength and dimensional stability. The tensile strength 0.56N/mm² passed the British and German standard specification, bending strength (modulus of rupture10.80N/mm²) was found nearest to Indian Standard but low German and British standard specification.

The three of the Astavarga (8) species, Lilium polyphyllum (Kshirakakoli), Polygonatum verticillatum (Meda) and P. cirrhifolium (Mahameda), were included in the study. The seed viability test showed very low viability (22.5%) for L. polyphyllum, which was improved by hand pollination. These species possessed seed dormancy from 28 days to over two years. Gibberelic acid treatments of 1000 and 2000 ppm in combination with scarification of soaked seeds gave species specific results for breaking seed dormancy.  The species included were described to have deep simple epicotyls morpho-physiological type of dormancy. They were found to have peculiar phenophases of seed germination, which have been discussed in detail along with diagrams.

More than 70% of the ornamental plant species grown in Indian gardens are of exotic origin, which directly or indirectly affect the existence of indigenous vegetation of the country. In the exploration to find out the possibilities of the still to be exploited indigenous species in gardens, Gymnostachyum febrifugum Benth. a herbaceous plant endemic to southern Western Ghats of India, is systematically evaluated here for its aesthetic potential. Very poor percentage of seed germination was found the major cultivation constrain. The highly condensed stem restricts vegetative propagation also. A successful vegetative propagation method using single noded stem sections and node splits with single axillary buds is developed. Being vegetative propagation means, it also helps to retain the selected desirable qualities uniformly through generations.

An experiment was conducted to find out the influence of different methods of extraction of seed from pods of Albizia lebbeck viz. splitting by hand, beating with plyable stick and threshing with paddy thresher and man-hour requirements, cost of extraction, seed recovery, viability, germination and seedling vigour was calculated. Results on viability test revealed that there was no significant difference on viability (97.5%) between the extraction methods. Germination recorded at 25 days after sowing revealed that seeds extracted through commercial paddy thresher gave maximum germination of 13% followed by beating with plyable stick and splitting with hand gave 9% and 5% respectively. Sulfuric acid treated seeds gave more than 95% germination irrespective of the extraction method when compared to control. While calculating the cost of extraction of 50 kg Albizia lebbeck pods, it was Rs. 87.50/- for paddy thresher, followed by beating with plyable stick (Rs, 187/-) and splitting with hand (Rs. 500/-). From this study, it could be concluded that Albizia lebbeck seed extraction through paddy thresher gave maximum seed recovery and germination without affect the viability with lesser time and cost.

The present study is based on primary data and the data was collected from randomly selected 160 lac growers in Bastar district of Chhattisgarh for the agricultural year 2012-2013.The study revealed that majority (61.25%) of the respondents belongs to young age group (up to 35 years). The education status indicates that majority (54.38 %) of the respondents were illiterate. The family size of the lac growers observed that majority (62.50%) of the respondents had small size of family (up to 5 members). As regard to social participation, it was found that maximum number of respondents (75.63%) having no membership in any organization. Results of the study enlighten the socio-personal condition of lac growers in Chhattisgarh which will be helpful in further studies.

Embelia ribes Burm. Myrsinaceae is a medicinal woody climber.  This species is reported to be vulnerable in the Western Ghats of penninsular India. Natural regeneration of E. ribes is poor due to over exploitation, fragmented populations, development of abortive embryos and slow germination of fertile seeds.  The present study is an attempt to analyse the interrelationship and association of morphological and biophysical characters in juvenile plants of Embelia ribes Burm. Ten growth characters and six biophysical characters were studied for the purpose in the case of a juvenile seedling population. Correlation analysis revealed the interrelationship of characters. Factor analysis has shown that the 16 characters under study can be grouped in to three factors. Relative water content in leaves showed the highest factor loading in factor 1followed by total chlorophyll content. In factor 2, number of leaves per tertiary branch showed the highest factor loading.

The study on ethnomedicinal plants used for skin diseases by the tribals of Visakhapatnam district, Andhra Pradesh, yielded 51 species of plants covering 49 genera and 39 families. Acanthaceae, Fabaceae and Solanaceae are the dominant families followed by Mimosaceae, Rutaceae, Apocynaceae, Asteraceae, Asclepiadaceae and Sterculiaceae and others. Habit-wise analysis showed the dominance of trees followed by shrubs, herbs and a climber. Plant part-wise analysis showed the maximum usage of leaf followed by seed and root, fruit, stem bark, whole plant, flower, latex and root bark.
