Forest soils supporting Sal-Shorea robusta (Roxb. ex Gaertn. f.) plantations in the foot hills of Darjeeling and Kurseong Divisions in West Bengal were studied for their physicochemical characteristics and carbon sequestration potential. Soils are acidic, high in organic carbon and clay content but low in soil reaction (pH) and bulk density (BD). Thick deposit of leaf litter and its decomposition products increase the soil organic carbon (SOC). Significant amount of clay content also increases the moisture content which helps in decomposing the organic matter, reducing the bulk density of soil and reduces erosion. Soil organic matter tends to concentrate with roughly more than half of the soil organic carbon in the upper soil horizons (0-30cm) at all the study sites. Among the study sites, Samardanga block registers lowest SOC while Bamanpukuri block shows highest SOC stock.

In-vivo and in-vitro germination trials were done on the teak (Tectona grandis) seeds collected from a farmland and forest plantation in Tamil Nadu. Under in-vivo pot culture condition very low germination percent of drupes was observed in seed collected from plantation(Top slip) and famrland (Kumulur). When true seeds isolated from the drupes were grown under in vitro condition in half strength MS medium, the germination percent was significantly increased up to 63.3 per cent. True seed germination among two teak sources showed the presence of mechanical dormancy which was a major limiting factor for poor drupe germination for deployment of superior genetic materials.

The Genus Cyathocline has been merged with Blumea following molecular phylogenetic evidence (Plastid trnL-F and nuclear ribosomal DNA ITS sequences data). While the type species, C. purpurea has been transferred to Blumea, other species have not been transferred. In light of this, new combinations are made here for C. lutea & C. manilaliana. C. purpurea var. alba and C. purpurea var. bicolor are synonymized under Blumea purpurea. B. manilaliana is reported here the first time from Maharashtra state.

Published: 20-09-2021
A total of 258 angiosperm taxa representing 75 families were evaluated as potential wild ornamentals in Andhra Pradesh, out of the total 845 wild ornamental taxa recorded from a five-year field study. The largest family is Fabaceae with 23 species and the largest genus is Ficus with nine species. Present paper deals with the critical analysis and systematic enumeration of all the 258 taxa in a tabulated form with their botanical names, habitat, habit form, ornamental category, longevity, district-wise distribution and voucher specimens.
