    Springer
    Cellular and molecular life sciences 34 (1978), S. 1015-1015 
    Details
    ISSN: 1420-9071
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The fine structure of the sieve element plastids ofBambusa vulgaris andSchizostachyum lumampao revealed the typical monocotyledonous type (P-type) with the cuneate proteinaceous bodies and lattice-like crystalloids; in addition, characteristically formed vesicles and tubulae could be observed. The diagnostic value of these plastids is also discussed.

    Occurrence of warts in bamboo species (1977)
    Springer
    Wood science and technology 11 (1977), S. 313-318

    Notes: Summary Warts have been observed in several bamboo species; they are present not only in vessel members and fibres, but also in the highly lignified parenchyma cells, especially in those of the elongated type. Among the 34 species studies only a few possess warts in all three cell types. The sizes of warts lie within the range observed for dicots and gymnosperms. There is no recognizable correlation between the occurrence of warts and the taxonomic grouping of bamboos. It has been suggested that the development of warts is associated with the lignification of the cell wall.

    On the fine structure of bamboo fibres (1976)
    Springer
    Wood science and technology 10 (1976), S. 231-246 
    Details
    ISSN: 1432-5225

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Summary The thick-walled bamboo fibres exhibit a polylamellate structure with alternating broad and narrow lamellae. Characteristically the cellulose fibrils in the broad lamellae are oriented almost parallel to the longitudinal axis of the fibre (2–20°), whereby there is a gradual but only slight increase in the angle from middle lamella to lumen. The narrow lamellae consist of fibrils oriented almost perpendicular to the cell axis (85–90°); this angle remains constant in all the successive narrow lamellae. The concentration of lignin is higher in the narrow lamellae than in the broad ones. Xylan seems to occur in a higher concentration in the narrow lamellae. The pits between the fibres are bordered. The results are discussed in relation to earlier data on wall structure and development. A model for the thick-walled bamboo fibre is presented with a new terminology for the various lamellae.

    On the origin of cotyledon and epicotyl inPotamogeton indicus (1962)
    Springer
    Plant systematics and evolution 109 (1962), S. 344-349 
    Details
    ISSN: 1615-6110
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The appearance of the first vertical wall in the terminal hemispherical cell of the proembryo ofPotamogeton indicus is indicative of the origin of the cotyledonary and epicotylary loci. The cotyledonary locus grows at a faster rate while the epicotylary region conspicuously lags behind. Topographically the cotyledonary and epicotylary loci are adjacent to each other, both being derived from the terminal tier of the proembryo. The subjacent tiers, including them tier, do not take part in the organization of the shoot apex but only contribute to the formation of the hypocotyl and root regions.

    Topochemical studies on the wall of beech bark sclereids by enzymatic and acidic degradation (1979)
    Springer
    Protoplasma 101 (1979), S. 197-215 
    Details
    ISSN: 1615-6102
    Keywords: Bark ; Enzymatic hydrolysis ; Vagus sylvatica ; Wall components ; Sclereids

    Topics: Biology
    Notes: Summary Sclereids isolated from the bark of beech (Fagus sylvatica L.) were delignified and treated with 1.3% sulfuric acid or with purified enzymes, viz., avicelase, carboxymethylcellulase, xylanase as well as combinations of xylanase and avicelase. Monitoring of the degradation was performed by quantitative liquid chromatography. Sulfuric acid dissolves about 30% sugars, especially hemicelluloses after 12 hours treatment. The avicelase (cellulase) and carboxymethylcellulase treatment degraded cellulose only to a very small extent. The xylanase degraded xylan selectively from the delignified sclereids amounting to about 60% after 51 hours incubation. The combined action of xylanase and avicelase brought about a xylan degradation of about 70%. Addition of avicelase to the initially xylanase-treated material resulted in the degradation of cellulase up to 25%. Electron microscopy of the variously treated samples showed the micromorphological changes effected and gave an indication of the topochemical distribution of xylan and cellulose. Sulfuric acid treatment removed wall components from all the lamellae of the sclereid wall, showing no definite pattern. Xylanase effects an intense decrustation of wall material both at the lumen boundary as well as near to the middle lamella, whereby the pattern of degradation is irregular; the cellulose fibrils also become well exposed. The addition of avicelase to xylanase-treated sclereid holocellulose creates an increase in the degradation, which is especially localized in the lamellated wall near to the middle lamella/primary wall region and at the lumen boundary. There appears to be a total hydrolysis of both matrix and fibrillar substances, characteristically more in the lamellae with longitudinal bow-shaped fibrils. Based on these results it is concluded that there appears to be no definite differential distribution pattern of xylan in the two lamellae. The higher contrast in the lamellae with transversely oriented fibrils is interpreted as resulting from the packing density of cellulose fibrils.
