A large number of tree species, especially of conifers growing in the Himalaya and a few broad-leaved taxa in the peninsular region, have been dendrochronologically analyzed in India. This paper is a review providing information as regards the present status and future prospects of tree-ring research in India. Many trees are recorded to have datable tree rings but only some of them have been used for climate reconstruction and other aspects, e.g., glacial fluctuation or palaeo-seismic dating. In future not only ring width which is widely used so far, but also other tree-ring parameters need to be analyzed for a better understanding of the regional climate and its linkage with other climatic phenomena in a global perspective.

. 2 ) Description – Wood diffuse porous. Growth rings present, marked by zones of dark coloured denser fibres. Vessels small to large, tangential diameter range 66–267 μm, mean 133 μm, solitary (about 70%) and in radial multiples of 2–5 (about 30%), occasionally in tangential pairs or clusters

dumbbell shape of tunnelling bacteria across the middle lamella, with the constricted part of the bacterium often present within the confines of this cell wall, suggest that tunnelling bacteria possess an ability to undergo shape changes apparently in relation to the physical and chemical constraints

preparation. A continuous radial position was assigned to each measurement based on its relative y -coordinate within the CT volume as the image y -axis is parallel to the radial direction of the specimen. Radial positions presented here are defined relative to the latewood boundary with the next annual

induced radial sieve elements (Sharma et al. 1980; Aloni & Barnett 1996). Recently, we found radial sieve tubes in the rays of the secondary xylem in Aquilaria malaccensis , A. sinensis , A. crasna and Gyrinops versteeghii (Thymelaeaceae, Malvales). The present study describes the occurrence and

. Because lignin (donor) and rhodamine (acceptor) form a FRET pair this facilitates the applicability of this technique to detecting probes within wood cell walls ( Donaldson et al. 2014 , 2018 ). In the present study, we extend this work to investigate differences in the cell wall porosity of sapwood

levels and presented in a table ( Table 3 ). RESULTS In total, 643 samples from 54 spinning wheels (24 from the Czech Republic, 7 from Slovakia, and 23 from Austria) were analysed (1). More than half of the samples (363) were taken from the frame parts. By contrast, the least represented are flyer parts

elements of each type were present. The phenotypic plasticity index (PIV) were calculated for all wood anatomical features, as suggested by Valladares et al . (2006), based on maximum and minimum means. The maximum plasticity, according to Valladares et al. (2006), is PIV = 1.0. The vulnerability and

variable. These six characteristic compounds, alpha-Copaene, gamma-Euesmol, Agaruspirol, Guaiol, Gualazolene, and 7-epi-gamma-Euesmol must be present in the volatile components of the heartwood of P. zhennan buried wood. The buried wood samples must meet both anatomical and chemical criteria before they

secondary xylem cells are not fully understood ( Funada 2008 ). The role of actin filaments in controlling the orientation and localization of cortical microtubules remains to be clarified. The aim of the present study was to investigate the spatial and temporal relationship between actin filaments and
