Abstract

In the present study, the storage and sequestration of carbon is described for leguminous trees (Cassia siamia, Dalbergia sissoo) vs. non-leguminous tree (Tectona grandis Linn. f.) in red lateritic soil of Chhattisgarh. Carbon concentrations of different components of eight year old trees were found to be 39.3-42.55 per cent, 41.06-43.3 per cent and 40.74-46.5 per cent, 44.4- 45.3 per cent in leaves, branches, stems and ischolar_mains respectively. Total storage of carbon ranged from 1,354.7 to 3,079.86 kg ha^-1. Out of the total stored carbon, 70 per cent were estimated to be in above ground parts while 30 percent in below ground parts. Storage of carbon was greater in leguminous trees. Similarly, carbon sequestration was also higher by leguminous trees compared to that of non-leguminous trees. Rate of carbon sequestration was a substantial i.e. 31 per cent for below ground ischolar_main the same for above ground components was 69 per cent. Study reveals the potential of leguminous trees in storage and sequestration of carbon in red lateritic soil and has implications for restoration of degraded land.

Abstract

Preliminary studies of four representative forest sites having dense, medium, regenerated and degraded forest plots of one ha area were conducted in the Achanakmar-Amarkantak Biosphere Reserve area for community structure and floristic diversity of tree layer. A total of 33 species were recorded. Density and basal area of trees in forest plots ranged from 240 (degraded forest) to 1270 (regeneration forest) stems ha^-1 and 23.65 (regeneration forest) to 37.57 (dense forest plot) m² ha^-1 respectively. Diversities in these forest plots were 1.46 to 2.24 (Shannon index), 0.61 to 0.83 (equitability), 2.95 to 6.06 (species richness), 0.41 to 0.53 (concentration of dominance) and 4.05 to 12.8 (Beta diversity). The beta diversity was highest at distributed forest plot. Forest represents the gradient in diversity and composition as high, medium, poor. Knowledge gained from such studies will help in framing the policy on R and D for conserving the forest forbiomass and diversity and its use on sustainable basis.

Abstract

The study was conducted on documentation of utilization of products of plant resources by local inhabitants of Achanakmar Amarkantak Biosphere Reserve (AABR) district Bilaspur, Chhattisgarh. Twenty six tree species were found in the study site and their products were collected and utilized for domestic and commercial purposes. Tree species come under sixteen families and the abundance of families of tree species were in the order of Anacardiaceae, Combretaceae and Euphorbiaceae. The study revealed that the demand for tree species like Buchanania lanzan (Char), Syzygium cumini (Jamun), Emblrea officinalis (Aonla), Aegle marmelos (Bael), Diospyros melanoxylon (Tendu) and Semecarpus anacardium (Bhelwa) etc. has alarmingly increased in the recent past due to their multiple uses and commercial exploitation. Few useful tree species such as Shorea rubusta (Sal), Terminalia alata (Saja), Madhuca indica (Mahua), Diosp yros melanoxylon (Tendu), T. chebula (Barra), T. beUirrea (Bahera), Cleistanthus collinus (Karra), Semecarpus anacardium (Bhelwa), Syzygium cumini (Jamun), Lannea coromandelrea (Gunja) and Anogeissus latifolia (Dhawra) are observed in the area. The study emphasized to conserve and domesticate these tree species for improving the livelihood oflocal inhabitants.

Abstract

Different auxin concentrations significantly influenced the ischolar_maining in J. curcas. Auxin concentrations of 500 mgl^-1 and 1000 mgl^-1 IBA showed minimal sprouting and ischolar_maining than untreated cuttings. The untreated cuttings yielded 93.50 % and 81.30 % sprouting, 62.60 % and 47.60 % ischolar_maining and 15.98 and 11.47 ischolar_mains/cutting in mist chamber and field, respectively. Cuttings from lower positions gave better (82.00 %) sprouting than middle (75.70 %) and upper (66.60 %) positions. Rooting varied from 35.40 % to 57.20 % for different cutting positions tested. For number of ischolar_mains/cutting, lower position had highest (10.79) and upper position had lowest (6.84) number of ischolar_mains. Among the three seasons tested, rainy season gave maximum (7.20 cm) ischolar_main length while it was lowest (5.19 cm) in winter. Rainy season yielded highest (11.33) ischolar_main number whereas, winter had lowest (6.36) ischolar_main number. Rooting was highest (58.90 %) in rainy season and lowest (29.50 %) during winter season. Sprouting was also maximum (91.70 %) in rainy season and minimum (51.30 %) in winter season. J. curcas is easy to ischolar_main and there is no need to apply auxin (IBA) externally. Without auxin (IBA) treatment, it produced sufficient sprouting and ischolar_maining. The study suggests growing thicker cuttings with 14-15 mm diameter in rainy season yields maximum sprouting and ischolar_maining.

Abstract

The present work aimed to study the regeneration status, species composition in natural and plantation forests of subhumid tropics in Barnawapara Wildlife Sanctuary during 2009-2010. A total of 33 species of 17 families were encountered. Regeneration status in all the study sites were dissimilar. Closed natural forest (960 stems/ha of seedlings and 220 stems/ha of saplings) displayed the better regeneration followed by open natural forest (350 stems/ha of seedlings and 90 stems/ha of saplings) and teak plantations (340 stems/ha of seedlings and 40 stems/ha of saplings) respectively. However under teak plantation Lagerstroemia parvilora has shown better regeneration. Tree stand density varied from 520 to 990 stems ha^-1 having basal area ranging from 21.50 to 47.30 m² ha^-1. It is evident that natural forest has an edge over plantation forest in terms of regeneration, species composition.
