STATE FOREST RESEARCH INSTITUTE Forest research in Tamil Nadu commenced in 1918 and the first Annual Research Report was published in 1919. Since then research activities are mainly focused on various thrust areas based on field requirements from time to time. Research Unit in Chennai formed much before Independence had carried out Research in the cultivation of important trees like Teak, Jack, Terminalia tomentosa, Terminalia paniculata, Dalbergia latifolia, Gmelina arborea, etc. The thrust of current forestry research activities is on reducing pressure on natural resource by increasing productivity through genetic and silvicultural improvement, making available technical know-how for agro forestry, wasteland development, eco-restoration and conservation of forest eco- system. With a view to increase availability of high quality planting material of economically important tree species for afforestation and reforestation of degraded forest and take up large scale tree cultivation in private lands, the research wing has established seed production areas, clonal seed orchards, seedling seed orchards and hedge stool in various research centres in Tamil Nadu. Micro and macro propagation for economically important and fast growing species like teak, sandalwood, silver oak, Melia dubia, Ailanthus excelsa, Eucalyptus, Casuarina has been standardized and propagules are being given RESEARCH THRUST AREAS I.TREE IMPROVEMENT - Genetic Combing - Progeny Trial - Clonal Evaluation Trial - Seed Orchard II.BIO-DIVERSITY CONSERVATION - Monoculture to Polyculture - Sandal Nucleus Plot - Population Dynamics Study - Species Recovery Programme III.MEDICINAL PLANT CONSERVATION - Assemblage of Germplasm - Creation of Plant Seed Centre - Research on Seed Handling - Package of Practice IV.AFFORESTATION PROGRAMMES - Wasteland Development and Agro forestry - Coastal Afforestation with Shelterbelt and Mangroves - Assemblage of Native Fodder Species - Energy Plantation V.SOIL NUTRIENT MANAGEMENT - Analysis of Forest soil - Organic Farming - Integrated Nutrient Management VI.SILVICULTURE - Introduction trial - Pre- Sowing Seed Management - Nursery Technology - Vegetative Propagation - Ideal Planting Techniques - Espacement Trial - Tree Architecture - Research on Bamboo VII.NTFP RESEARCH - Sustainable Harvest Studies on Medicinal Plants - Tree Borne Oil Seeds VIII.FOREST UTILISATION - Post Harvest Timber Management - Economic Appraisal of NTFP - Forest Produce.

TREE IMPROVEMENT Genetic combing It is essential to select different candidate plus tree species for different characteristics. Seedlings raised from these species will have superior genetic characteristics. Seeds are being collected from the plus trees to raise high quality seedlings. Work of marking GPS location of each CPT was continued and about 500 CP trees thus identified with reference to different species. GENETIC COMBING: -Candidate Plus Trees (CPT’s) of the following species have been identified for collection of good quality seeds. 1 Acacia ferruginea 8 Albizzia lebbeck 15 Calophyllum inophyllum 2 Acacia leucophloea 9 Alstonia s cholaris 16 Canarium strictum 3 Acacia mearnsii 10 Artocarpus hirsutus 17 Cassia fistula 4 Acacia nilotica 11 Azadirachta indica 18 Casuarina junghuhniana 5 Aegle marmelos 12 Bassia latifolia 19 Couroupita guianensis 6 Ailanthus excelsa 13 Boswellia serrata 20 Crataeva magna 7 Ailanthus malabaricum 14 Bridelia retusa 21 Dalbergialatifolia 22 Derris indica 34 Lagerstroemia 46 Sapindus lanceolata emarginatus 23 Dillenia pentagyna 35 Melia dubia 47 Shorea talura 24 Eucalyptus globulus 36 Millingtonia hortensis 48 Sterculia urens 25 Eucalyptus grandis 37 Mimusops elengi 49 Strychnosnux- vomica 26 Feronia elephantum 38 Mitragyna parviflora 50 Tamrindu sindica 27 Gmelina arborea 39 Phyllanthus emblica 51 Tectona grandis 28 Gmelina arborea 40 Pithecellobium dulce 52 Terminalia arjuna 29 Hardwickia binata 41 Populus deltoides 53 Terminalia bellarica 30 Holoptelea integrifolia 42 Premna tomentosa 54 Terminalia catappa 31 Hydnocarpu 43 Pterocarpus 55 Terminalia chebula spentandra marsupium 32 Jatrophacurcas 44 Pterocarpus 56 Toona ciliata santalinus 33 Khaya senegalensis 45 Santalum album 57 Ziziphus jujuba Red Sander at Seshanchavady Meliadubia Teak – Trichy SEEDLING SEED ORCHARDS FOR THE FOLLOWING SPECIES ARE BEING ESTABLISHED. 1 Acacia chundra 12 Chloroxylon 23 Pterocarpussantalinus swietenia 2 Acacia mearnsii 13 Derris indica 24 Santalum album 3 Aegle marmelos 14 Eucalyptus citriodora 25 Sapindus emarginatus 4 Ailanthus excelsa 15 Eucalyptus globulus 26 Simarouba glauca 5 Albizia amara 16 Eucalyptus grandis 27 Swietenia macrophylla 6 Albizia lebbeck 17 Eucalyptus 28 Swietenia mahagony tereticornis 7 Artocarpus integrifolia 18 Feronia elephantum 29 Syzygium cuminii 8 Azadirachta indica 19 Gmelina arborea 30 Tamarindus indica 9 Bassia latifolia 20 Holoptelea 31 Tectona grandis integrifolia 10 Casuarina 21 Melaleucaalternifolia 32 Terminalia chebula junghuhniana 11 Casuarina 22 Meliadubia kapankuppang CLONAL SEED ORCHARDS FOR THE FOLLOWING SPECIES ARE BEING ESTABLISHED 1 Acacia mangium hybrid 5 Derris indica 9 Santalum album 2 Ailanthus excelsa 6 Eucalyptus globulus 10 Sapindusemarginatus 3 Casuarinaequisetifolia 7 Meliadubia 11 Simaroubaglauca 4 Casuarinajunghuhniana 8 Pterocarpussantalinus 12 Tectonagrandis GERMPLASM BANK FOR
