The paper deals with the variation in wood properties of ten tree species namely Adenanthera pavonina, Artocarpus heterophyllus, Bridelia retusa, Ceiba pentandra, Hydnocarpus wightiana, Hymenodictyon excelsum, Peltophorum pterocarpum, Pterocarpus santalinus, Samadera indica and Tectona grandis grown in the College of Forestry, Kerala Agricultural University, Vellanikkara, Thrissur, Kerala. Stem discs of one inch width were cut at the base, middle and at the top of stem from a randomly selected ten trees of each species for the estimation of physical properties and the specific gravity of wood. Study reveals that, the discs of Adenanthera pavonina recorded highest proportion of heartwood in basal portions followed by Tectona grandis while sapwood percentage was maximum for Samadera indica and Peltophorum pterocarpum. The highest heartwood sapwood ratio was for Tectona grandis in case of disc from the base. The specific gravity of wood of various tree species ranged from 0.14 in Pterocarpus santalinus to 0.96 in Hymenodictyon excelsum.Keywords

Mahua (Madhuca longifolia var. latifolia Roxb. A. Chev.) tree has religious and aesthetic value in the ethos of many tribes of Gujarat, India. Traditional knowledge of the people about the various uses of mahua is shrinking rapidly due to the change in socioeconomic status. The present study was conducted to draw the utilization pattern of mahua resources and to document the traditional knowledge of the people involved in its usage in Gujarat. Information regarding pattern of utilization and traditional knowledge about mahua was collected using the participatory rural appraisal method. Results highlighted interesting information on traditional knowledge about processing, product development and medicinal value of mahua resources. The species is under threat and receives less care compared to the benefits drawn from it. Therefore, sustainable management of this valuable species is needed by taking a lesson from traditional knowledge.Keywords

Melia dubia Cav. is an important indigenous, short-rotation, multipurpose tree, advocated as a good raw material for pulp and plywood industries and high-quality timber for various purposes. Multiplication and conservation of its selected superior genotypes are prime challenges in commercial forestry. The present study was conducted to analyse ischolar_main sucker ability. Roots sections collected during November–December and treated with indole-3-butyric acid @ 4000 ppm in nursery beds having soil : sand : vermicompost (in the ratio of 2 : 1 : 1) started juvenile shoots emergence after 30–35 days, with 90% shoot emergence and 85% establishment. No shoot emergence was observed from the ischolar_main section collected during February–March. The clonal bank established in this process attained a diameter of 5–8 cm (10–12 cm above ground) in one year. The study shows that the ex situ detached ischolar_main sucker protocol route can be adopted for cloning M. dubia without sacrificing the superior genotypesKeywords
