A new anthraquinone (3,8-dihydroxy-2-methyl anthraquinone), named tectone (1), along with fourteen known compounds (2-15) comprised of five terpenoids (2-5, 15), four flavonoids (6-9), three flavone glycosides (10-12), and two phenolic glycosides (13-14) were isolated from the chloroform and n-butanol fractions of the ethanol extract of Tectona grandis leaves. Attempts were made to synthesize compound 1. This resulted in the synthesis of three additional anthraquinones (16-18), out of which compound 16 is new. The structures of all compounds were established by spectral analysis. The isolated

Abstract:

Tectona grandis (teak) is an increasingly important timber resource globally. It is native to Asia, including Thailand. In this paper a new species of Barriopsis, B. tectonae sp. nov., is described from a dead T. grandis branch collected in Thailand. Barriopsis tectonae can be differentiated from the two previously described species of Barriopsis; B. fusca and B. iraniana, by its ascospore and conidial dimensions. Phylogenetic evaluation of the ITS, TEF1-α and BT genomic regions provide further evidence that B. tectonae is a novel species.

Tectona grandis (teak) is one of the most important economic timbers worldwide. Limited studies exist on the potential pathogens of these trees. Fungi in the Botryosphaeriaceae are cosmopolitan opportunistic pathogens, endophytes and saprobes of numerous hosts. Both symptomatic and asymptomatic branch and stem sections, as well as leaves were collected from T. grandis in plantations and forests in four provinces of northern Thailand with the aim of identifying species of Botryosphaeriaceae associated with these trees.

Abstract:

Fungal diseases cause serious seedling mortality in nurseries and threaten future seedling production for forest regeneration. To abate this menace, knowledge about them is key. Therefore, this study aimed at determining the incidence and severity of fungal diseases of forest seedlings in the Central Forest Nursery of Tamale, Ghana. Khaya senegalensis, Tectona grandis and Polyalthia longifolia in the nursery were infected with eight fungal pathogens and an unidentified fungus causing leaf blight, wilt, and dumping-off diseases. The pathogens included Rhizoctonia sp., Fusarium sp., Corrynespora

Abstract:

The international market has recognized the high value of Tectona grandis L.f. plantations, requiring the development of reliable and accurate tools and techniques to quantify forest stocks accurately. In this study, we developed suitable equations to estimate the stem diameters and volume of Tectona grandis trees in the central-western region of Brazil, evaluating the stem form change points (FCPs) and testing the stratification of data as a measure to control their variation. The Schöepfer model was tested in the study of the FCPs of the stem, and single equation, segmented and variable-expo

Two sizes selected were 16cm and 38 cm in diameter at breast height (dbh). Sapflow meter used to assess the sap velocityrates within 24 hours. Diurnal sapflow of Tect ona grandis shows that mean velocity ishigh during day time compared night time. Small diameter has high sapflow comparedto that of bigger diameter. A flow rates was high at the inner layer and less at outer layerfor smaller tree. The variation was vice versa when the tree getting bigger.
