    Glue adhesive properties of arecanut leaf sheath boards
    (2007-02) Annamalai, S.J.K.; Menon, S.R.K.; Nayar, N.M.
    3-ply arecanut leaf sheath boards were made at the laboratory with two veneers of arecanut leaf sheath and one veneer of wood under various combinations and with different glues namely starch glue (cold pressing), animal glue (cold pressing) poly vinyl acetate (Fevicol-Pidilite -cold pressing), Epoxy resin adhesive (Araldite-Ciba Geigy-cold processing) and urea formaldehyde (hot pressing). The boards were tested for their glue shear strength and water resistance in accordance with the IS specifications for tea-chest grade plywood. Areca sheath boards made with UF resin adhesive and wood veneer as core were found to have 50% more wet glue shear strength than the other areca sheath boards. Use of extenders like tamarind seed powder and deoiled sal meal up to 15 % to the UF resin adhesive and the type of wood used were found to have no adverse effect on the glue shear strength of the boards. Though the areca sheath boards satisfied only 50% of the IS requirements for tea chest grade plywood, they were found to have better wet glue shear strength over the locally purchased non-ISI grade tea chest plywood.

    Some Observations on the Growth of the Coconut Fruit With Special Reference to Some of the Changes Undergone by the Fibrous Constituent of its Mesocarp
    (2007) Menon, S.R.K.
    In view of the facts that the coconut, unlike many other fruits, in composed of several physically and chemically distinct components, that each of these components has unique economic value, and that the fruit takes normally more than a year to ripen and fall down, it was thought expedient to tract the growth of the fruit with particular reference to the changes occurring in its several components. It is true that fairly detailed descriptions of the growth of the fruit are found in snob classical treatises on the coconut palm as those of Copeland [1931], Sampson [1923] and others, but those studies have not been of the strictly scientific type involving due insistence on all possible measurements and analyses. The present study is an attempt to exclude that serious defect and indicate a possible line of successful attack of several problems relating to the growth of this important agricultural product.
