“…Both values are lower than their corresponding values from gmelina handsheet. But the tensile index is comparable with 59,3 kN.m/kg and 51,8 kN.m/ kg values earlier reported for switchgrass and Miscanthus x giganteus, both non-woody biomasses (Cappelletto et al 2000, Law et al 2001, Ai and Tschirner 2010. Better still; the tear index of bamboo handsheets is three times higher than those of the aforementioned pulps of hardwood and softwood.…”

Two common Nigerian-grown biomasses, gmelina (Gmelina arborea) and bamboo (Bambusaa vulgaris) have been pulped and their fibre characteristics and paper properties examined. The results of their chemical compositions showed some fair similarities. The amount of glucose in the pulps of both biomasses indicated their suitability as lignocellulosic materials for pulping. Their pulp yield ranged between 48,0-54,1%, which fell within the acceptable range for good pulpwoods. The analysis of their fibre dimensions revealed that bamboo fibre has a wider fibre length distribution and higher fine length content. Gmelina and bamboo had weighted mean fibre lengths of 0,93 and 2,07 mm and mean fibre widths of 24,1 and 16,9 µm, respectively. The Runkel ratios of the samples were 0,4 (gmelina) and 0,9 (bamboo): this is indicative of their suitability for paper making. Mechanical properties of handsheets obtained from gmelina compared fairly well with South African pulpwoods (Eucalyptus grandis and Pinus paluta). Bamboo exhibited better tear index values than these woods but with lower sheet density and tensile index. These properties were significantly improved in handsheets obtained from blends of gmelina and bamboo, raising the prospect of producing paper from blends of both raw materials in Nigeria.

“…M × giganteus is a perennial C4 grass that is sterile due to its hybrid genotype, but can be propagated by rhizome division or by micropropagation. The hybrid grows rapidly and develops a high biomass under relatively low input levels (Schwarz et al, 1994;Lewandowski, 1998;Cappelletto et al, 2000;Kaack et al, 2003;Clifton-Brown et al, 2004;Cosentino et al, 2007). In addition, the hybrid makes highly efficient use of water and nutrient resources, and is of value for carbon sequestration and high biomass yields in a range of different climates and environmental conditions such as shallow, dry, cold, and waterlogged soils (Clifton-Brown and Jones, 2001;Clifton-Brown et al, 2002, 2007Naidu et al, 2003).…”

“…This is because of its high yield potential at low inputs (Beale & Long, 1995 ;Lewandowski et al, 2000), easy harvesting and handling (Venturi, 1998) and good combustion quality (Jørgensen, 1997). Miscanthus fibres can be used for papermaking (Cappelletto et al, 2000), and the whole stems can be used for Light Natural Sandwich materials (Schwarz et al, 1998a) or for thatching, for which they are also used in Japan (Walsh & Jones, 2000).…”

Resurrection plants are a perennial fascination to botanists. The transformation, within a few hours (or even minutes) of supplying them with water, from a plant that has all the appearances of being dead -dry, brown, crisp and shrivelled -to a plant that is obviously living and functioning -turgid, green, pliable and growing -suggests the miraculous. Studies of the complex processes of restoration and repair have been made on a number of resurrection plants, and at many levels of organization from molecules through membranes, organelles and cells to the whole plant (Gaff, 1989). The woody South African shrub Myrothamnus is the most extreme example of such plants, in that it has the highest level of organization to be repaired. It is transformed from lifeless-looking sticks with a water content below 5 % to a flourishing bush in a day after its roots receive water. Two papers in this issue from Ulrich Zimmermann's group in Wu$ rzburg concentrate on the restoration of the functioning hydraulic systems of the stems (see pp. 221-238, and 239-255 Before the rehydration of the still-viable cells and tissues of the shoot, water has to be delivered to them through the non-living xylem pipelines, which have been emptied of water. The tracheary elements must be refilled and the water flow through them re-established. Two studies of these processes have already been published by a group in South Africa (Sherwin & Farrant, 1996 ; Sherwin et al., 1998). The present papers concentrate on the following questions :$ What is the spatial and temporal scale of the rise of water in the stems ? $ What forces, capillary or root pressure, are driving water movement ? $ Does the hydraulic system of Myrothamnus have special features or properties that distinguish it from plants that cannot rehydrate from dryness ?The text is less ' innocent ' than it appears. Contained within it is a subtext with linkages to several very contentious issues in current work on plant water relations. Capillary forcesThe advance of water through dry stems was followed with dye tracers, by the changes in refraction shown by wet tissue, and by the recurving of dry appressed leaves. The measured rates were fitted to an elaborate model of the kinetics of capillary advance through narrow tubes. The important variables in the model are the tube diameter and the contact angle formed at the water-air-vessel-wall interface. The data point to an advance of the water through very narrow tubes (c. 1 µm) with large contact angles (c. 70 %) (i.e. hydrophobic walls). Rate of water advance decreased with time (distance) and the walls became less hydrophobic. Capillarity did not provide sufficient force to account for the rise of water to the height of the stems in a day. Root pressureTo drive water up the dry 80-cm stems at the necessary rate required the application of pressures greater than 8 kPa. Although the South African group measured root pressures no higher than 2n4 kPa (which would not be enough to refill the stems completely), the Wu$ rzburg group found pressur...
