        what are the timber and wood characteristics of kattu punna?


        • #5

          Blooms from January to May and natural items experienced in the midst of June to August,

          generally connecting till November.

          Timber, wood qualities and businesses

          Log quality

          Logs broad measured, straight and clean, up to 20 m length and 4 m bigness. The

          timber heater season truly well at low temperatures, with irrelevant surface


          Wood properties and vocations

          The wood is reddish white to pale ruddy chestnut with dull streaks and is

          interlocked or straight-grained, medium textured, strong, adaptable and

          humbly strong. Specific gravity of the wood is around 0.51 and weight is

          around 655 kg/m3 (Nazma et al., 1981). The wood is used basically for railroad

          sleepers, rafters, planking, straightforwardness furniture, shafts, posts, midsections,

          numerical instruments, compasses and overall improvement work. It is a

          class-one plywood and Rama Rao (1914) had also reported the pulping quality

          of the wood.

          From the bark of the tree, an astringent gum, dissolvable in chilly water, is

          removed (Chandrasena, 1935). The seed parts contain around 70 for every penny

          rosy cocoa oil with a hostile aroma, which solidifies at a temperature

          of around 25 0C. The oil is used as an illuminant.

            hey how is seed collection, processing and storage of kattu punna carried out?

              Seed gathering

              Regardless of the way that, seeds age and fall on the timberland floor in the midst of the first rainstorm

              season in July-August, they will be routinely impacted by borers or devoured by

              monkeys, as the seeds are smooth. Consequently, characteristic items can be amassed from the

              mother trees by trimming the terminal branchlets, when they age and get the opportunity to be

              yellowish or faint purple in shading. The natural items consequently accumulated are to be depulped

              besides, dried under shade before sowing. Results of light weight and minimal size are

              to be discarded in the midst of the get ready period.

              Seed traits

              Full developed natural items are drupaceous and ovoid or subovoid alive and well, with an ordinary

              size of 3.5 cm x 2.7 cm ). Around 166-175 new sustenances developed from the beginning

              dried natural items measure one kilogram. On an

              ordinary, the seeds are 2.4 cm x 1.6 cm in

              size, elliptic alive and well and cocoa in shading

              ). Around 800-850 dried seeds weigh

              one kilogram


              • #8
                The dried seeds can be set away for not precisely

                six months without loosing much sensibility (Rai, 1999). In any case, in the midst of the

                present study, they were sown within a month subsequent to assembling to get most prominent

                Seeds Brown Elliptic 2.4 x 1.6 800-850

                Seed vermin and control

                The seeds fallen on ground were found to be swarmed by bug disturbances (shot-crevice

                borers) and oftentimes monkeys moreover expend them. Most damage was brought on by

                shot-crevice borers. The scolytidis Coccotrypes species and Thamnurgides species

                are known not the results of a blend of woods trees (Beeson, 1941). These

                bugs generally start to ambush while the natural items are on the mother trees.

                Standard social event and annihilation of impacted normal items have been suggested for

                managing the aggravation in seed stands. Thought must be taken to pick common items free from

                bug attack by checking and discarding the hurt ones.

                    Seeds of C. polyanthum accumulated from Vazhachal, Vazhachal Forest Range and

                    attempted by smudging surface methodology exhibited five sorts of limit developments, microorganisms and

                    actinomycetes (Table 4.1.2). Sorts of Trichoderma, Aspergillus and

                    Penicillium were the most otherworldly developments in non-surface sterilized seeds.

                      Seeds were sown in standard nursery beds at a separation of around 10 cm, in

                      23 cm x 17 cm size, loaded with preparing blend, amid September, 2000. About

                      one kilogram of seeds is adequate to sow in one standard nursery bed, and in

                      the instance of polypots, one and only seed each was sown, in light of the huge size of

                      seeds. A dried specimen of organic products all things considered was likewise sown in ploypots, to record the

                      variety in germination rate. The seeds and natural products sown were secured

                      with a slender layer of soil and sand blend (1:3) and the shaded informal lodging

                          in the wake of sowing. Seedlings stayed in the cotyledonary stage for 10-20 days taking all things together

                          the diverse specimens strove for germination.
