Abstract: Sea anemones are brightly coloured marine invertebrates belonging to the order Actiniaria of class Anthozoa and phylum Cnidaria. Globally, more than 1000 species of sea anemones have been reported. However, in India only 54 species belonging to 40 genera and 20 families have been documented1 . Sea anemones can reproduce either sexually or by parthenogenesis. In sexual reproduction, external fertilization occurs followed by the development of planktonic planula larvae, which become single polyps. In asexual reproduction, the sea anemones divide by budding or binary fission.

Abstract: Calopogonium mucunoides has been widely used as a pasture legume, cover crop and nitrogen fixing plant in tropical regions of the world. The present study investigated the effect of different pre-treatments on germination per cent (GP), mean germination time (MGT), germination value (GV), peak value (PV) and germination index (GI) of C. mucunoides. Experiment was conducted in Complete Randomized Design with four replications of 25 seeds for each treatment and control (25 seeds × 4 replicates × control/hot water/acid scarification/sand scarification/growth promoters = 52 experimental units). Seeds were subjected to different pretreatments viz., Hot water soaking at 40°C, 60°C, 80°C, 88°C; acid scarification using conc. H2SO4 98% (1% (v/v), 3% (v/v), 5% (v/v); sand scarification, GA3 treatment (500ppm and 1000ppm); KNO3 treatment 0.1% (w/v), 1% (w/v), 3% (w/v). Results of germination parameters such as GP, MGT and GV were subjected to analysis of variance (ANOVA). Dunnett t (2-sided) statistical analysis and Post hoc Tukey HSD method was used for testing the significance between treatments. Results concluded that control seed produce the GP of 56% while sand scarification and hot water soaking of seeds enhanced the GP range from 80-97%.

Abstract: Eucalypts are among the most widely cultivated forest trees in the world under a range of different climates for products that include pulp, paper fuel wood and solid wood products such as poles, furniture and construction timber. Large scale plantations have been raised in government owned and private farm lands; the planting is continuing. Productivity and profitability of plantations of Eucalyptus have been revolutionized with the development of genetically improved, fast growing and high yielding clonal planting stock of Eucalypts. Eucalypts clonal planting has been said to have advantages which includes quick provision of benefits associates with fast growth, short rotation for production of pulp wood (of around 70 t ha-1 in 6 years) ready marketing and easy establishment and less maintenance needs. Clonal planting one among the approach for management of water and nutrients compared to the other conventional strategies. Studies relating to clonal difference and evaluation for dry matter production will help to overcome productivity loss due to deficit rainfall and optimum utilization of available natural resources for higher wood production. The present study was carried out to test the hypothesis that there exists a clonal variation in growth, biomass production and components and the present study gives an insight in to clonal variation with reference to growth, biomass production and components.

Abstract: Eucalyptus is a versatile genus with a particular significance for paper pulp, and it is extensively cultivated in India's marginal lands. Eucalyptus camaldulensis and E. tereticornis are highly preferred due to its optimal pulp yield, excellent fibre quality and good abiotic stress tolerance properties. Marker-assisted selections have played a major role in eucalyptus breeding programs. The use of genotyping-by-sequencing (GBS) approach for a largescale single nucleotide polymorphism (SNP) discovery and genotyping of an inter-specific mapping population, Eucalyptus tereticornis × E. camaldulensis are reported in this study. Reduced representation libraries of 81 F1 progeny were sequenced and number of SNPs considered for linkage analysis was 96,377 single nucleotide substitutions, most of which (54.03%) represented transition events. Totally, 1999 and 4206 SNP markers were mapped to female (Eucalyptus tereticornis) and male (Eucalyptus camaldulensis) map, respectively. Consensus map consisting of 4844 markers were placed on a linkage map, which spanned 1367.6 cM and had an average of one marker every 0.29 cM corresponding to a physical distance of about 0.66 Mb. The map was utilized to identify six quantitative trait loci (QTLs) associated with adventitious rooting traits of stem cuttings accounting for phenotypic variations ranging from 7.18% to 9.17%. Analysis of the genomic sequence corresponding to six QTLs led to the identification of 201 putative candidate genes and 4 key genes were related to adventitious rooting specific expression. The integrated strategy utilizing the identified QTLs along with the available genome could serve as a platform for candidate gene identification for molecular breeding of eucalypts.

Keywords: Tree Species, Mass Multiplication, Mini Clonal Technology.
Abstract: The growing importance on promotion of plantation and agroforestry in India demands production of quality planting materials to satisfy the demands of tree growing farmers and wood based industries. The National Forest and Agroforestry policies also prioritized ensuring quality seedling production for successful establishment of forestry and agroforestry plantations. As of now, most plantation activities in the country are carried out through seed based seedling production barring few exceptions which exhibited wide variations in growth, yield, productivity and adoptability. Under such circumstances, The Forest College and Research Institute (TNAU) has developed species specific mini clonal technology for wide range of pulpwood, plywood and timber species viz., Eucalyptus, Casuarina, Melia, Teak, African Mahagony, Toon and Kadam. This innovative mass multiplication technology exhibits greater potential of adoption across regions towards mass multiplication of wide range of species and to ensure quality seedling production as envisaged in National Agroforestry policy. The rapid multiplication coupled with increased rooting efficiency in a short duration and elimination of epigenetic variation attracts this technology as a most promising in forestry and agroforestry plantation development program.

Abstract: Red sanders are one of the highly valued tree species in the world, native to south parts of Eastern Ghats (Andhra Pradesh and Tamil Nadu). As the success of any tree improvement depends upon the amount of variations found in heritable traits of populations and is basis for future genetic improvement, the present study was carried out to assess the variations in growth traits, bark, sap- and heartwood of different populations of red sanders in Karnataka. Hullikere (43 years), K.Settihalli (47 years), Jharakabande (32 years), Nallal (42 years), Yeshwanpur -A (42 years) and Yeshwanpur-B (42 years) in Karnataka. Significant variability found in growth traits viz., girth, straightness, tree height and sap- and heartwood content of the Red sanders. Time of heartwood formation varies within and between trees as well as between the populations. Both content and colour of heartwood vary even in the trees of same girth in a stand. No heartwood was found in trees which had girth <37, <41, <44, <46 and <48cm at breast height in Jharakabande, Hullikere and Yeshwanpur-B, Yeshwanpur A, Nallal and K.Settihalli plantations, respectively. The heartwood formation was not depicted any trend with tree size and age of trees in the Redsanders populations.

Abstract: The standing tree volume is a measurement of the amount of merchantable volume and available growing stock in forests and trees outside forest areas. The precise estimation of the tree log volume plays an important role in sustainable forest management and also in trees outside forest areas. Several scientists have derived various tree log volume calculation formulae, which are used in estimating standing tree volume. The Gujarat State has very rich forest biodiversity. The forest department has done very good work in conserving existing forests and achieved outstanding success in planting and raising trees outside forest areas through a successful social forestry program in the State. The efforts through public participation have resulted in to increase in forest cover of the State. The present investigation was carried out at Gujarat Forest Research & Training Institute, Gandhinagar campus to develop an empirical formula for estimating standing timber availability from different selective tree species of Gujarat. The attempt has been made to measure Girth at Breast Height (GBH), Clean Bole Height (CBH) of selected tree species, and round log volume was calculated using a quarter girth formula assuming it to be a cylinder. Considering principal factors behind tree growth that 1) the height is a function of girth, 2) young, aged tree grows at a double rate that in middle age and 3) mature tree hardly puts any height or girth, a general growth formula has been derived. The general growth formula was validated for different species based on actual measurement of effective height. Finally, the empirical formulas were developed based on the Regression of derived formula V = A G2 10-5ebG for different tree species.

Thus, plant mating systems play an important role in shaping the genetic composition of progeny generations. Institute of Forest Genetics & Tree Breeding (IFGTB), Coimbatore has established Seedling Seed Orchards of Acacia auriculiformis in Southern States (Tamil Nadu and Kerala) of India. Two successive generations of this species were studied for its mating system based on microsatellite markers. Five microsatellite loci were studied among the three hundred half-sib progenies of both first and second orchard populations. Out-crossing rate was estimated The range of the maternal, paternal genotypes among the individuals in the family was also studied in the orchards. The present study indicated high out-crossing rate in first- and second-generation orchards population and it reflects that this species is highly out-crossed. The gene frequency estimates of the first- and second-generation progenies were studied that there was no significant variation in the pollen and ovule gene frequency estimate in both generations. The range of the maternal genotypes was 1 to 2 among the individuals in the family. The high out-crossing rate (tm=0.98; SE= 0.05; tm=1.0; SE=0.02) in the orchards indicated that the species is predominantly out-crossed.

Keywords: Rhododendron arboreum, Cotyledonary Leaves, Charcoal, Genomic DNA.
Abstract: The extraction of high-quality DNA from different plant source is a limiting factor in genetic diversity studies of any tree species. DNA extraction is the preliminary and essential step for almost all molecular marker based genetic studies. High-quality DNA extraction from cotyledonary and mature leaves of Rhododendron arboreum is extremely difficult due to the presence of high concentration of polyphenols and polysaccharides. These contaminants, if present in the extracted DNA severely affects the PCR amplification. Therefore, a method of DNA extraction from the cotyledonary and mature leaves has been developed. Solubility of polysaccharides was minimised with high salt concentrations (3M) and polyphenols removed by adding, Polyvinylpyrrolidone (2%) and activated charcoal (1%) in the DNA extraction buffer. Additionally, RNase-H was used to remove RNA contamination. The extracted DNA was quantified using bio-spectrophotometer. DNA was obtained with concentration ranging from 2.30 to 4.70μg with the absorbance ratio of 1.80 to 1.88, per milligram of cotyledonary leaves and 4.25 to 7.70μg with the absorbance ratio of 1.80 to 1.88, per milligram of mature leaves. Further, quality of extracted genomic DNA was assessed by random amplified fragment length polymorphism (RAnd simplePD) a sequence repeat (SSR) markers.

Keywords: Correlation, Path Analysis, Casuarina junghuhniana, Saline Water.
Abstract: Eight clones of Casuarina (four of Casuarina junghuhniana and four of interspecific hybrids of Casuarina equisetifolia × C. junghuhniana) were subjected to saline water irrigation with different concentrations of NaCl viz., 0, 40, 80 and ;120 mM. After twelve months of study period, plant height, collar diameter, plant fresh weight, root length, proline, total soluble sugars reducing sugars, relative leaf water content, and Na+/K+ ratio showed high and positive correlation with plant dry weight. Path analysis revealed that collar diameter, root length, reducing sugars and relative leaf water content had the highest direct effect on plant dry weight and can be collectively used as selection criteria for improvement of Casuarina for increasing biomass.
