Japanese cypress

For every point on the curve in figure 1 characterizing rain and snow, there is a corresponding average air temperature, as may be seen in figure 25. Consequently we looked for a similar dependence and the slope of 8 to occur in trees which ingest rain. We found the slope of 8 in a Japanese cypress [25] measured for the years 150 - 1970 A.D. But in the sequence of. German oaks which we measured [28-31] we reported that we did not find a slope of 8, and we listed our measurements.

As the cultivation of cotton in Japan is declining there is a shortage of cotton seeds on the market, but of.course a large amount of cotton is produced in the USA, India and China. At present, in place of the.cotton seeds many of the fireworkers use rice chaff for small or medium shells and Japanese cypress seeds for large shells. 

Cotton seeds are most popular as cores because the surface of the grain is downy so that it holds the composition very well. Rice chaff is also popularly used for smaller class shells. For larger shells seeds of Japanese cypress are used in mountainous districts and pieces of cork j are also used for the largest shells. In any case core material must be roughly spherical, must hold the composition well, and should not allow the fire to remain in it after the explosion and if possible it should be ultimately biologically degradable. 

The exothermic onset temperature or EOT of the sawdust of each wood species is determined by comparing the TG-DTA curve recorded in air with the curve recorded in nitrogen gas. The EOT of the sawdust of every wood species is, however, one of the data of poor reproducibility, so that it is rather difficult to determine distinctly the value by means of TG-DTA. As an example, when DTA is performed for the sawdust of Japanese cypress, which is one of wood species relatively hard to heat oxidatively, in air and in nitrogen gas, respectively, it is almost impossible to distinguish the enthalpy change of the sawdust recorded in air from the change recorded in nitrogen gas at... 

Comparison of the oxidatively-heating property of the sawdust of a fresh lumber of Japanese cypress with that of the sawdust of an old lumber of the same wood species... 

As lo Japanese cypress, it is seen that the calorific value of the sawdust of the old lumber is a little larger than that of the sawdust of the fresh lumber. 

Comparison of the oxidatively-heating curve, of the sawdust of a fresh lumber of Japanese cypress charged in the draft cell, into which air is supplied, and subjected to the adiabatic oxidafively-heating test started from a Tg near 150 "C, recorded in temperature increments of 3 K from the corresponding standard temperature, with, the oxidatively-heating curve of the sawdust of an old lumber of the same wood species placed under the same conditions as the former, is given in Fig. 94.

The physical properties of wood-chip of used timber crushed by a hammer-type crusher were investigated. The samples of wood-chip were taken from five by-product treatment plants in Kanto area. Table 1 shows the physical properties of the wood-chip mentioned above. In the table, the sorts of timber for the industrial raw materials were conifer trees e.g. Japanese cedar, Japanese cypress, pine and Japanese beech. The wood-chip for fuel were mixed of conifer trees and broad-leafed trees. Photo. 1 shows the sample of wood-chip used for this experiment. 

Assembling a pagoda expresses to assemble the unique natural character of Japanese cypress wood". This means that every tree has its own unique characteristic and the individual nature of trees should be taken into account when assembling them. 

Somatic Embryogenesis and Efficient Plant Regeneration in Japanese Cypresses... 

Although the initiation of ET was also possible without any additional auxin and cytokinin supplements required, exogenous PGR were found to be essential for the continuous maintenance and proliferation of ET (Fig. 2B). Conversely, the maintenance and proliferation of EC on media with no PGR was reported for Pinus radiata (Smith, 1996). He indicated that the use of PGR is not necessary, and that some cell lines maintained on a medium with 2,4-D and BAP lose their plant-forming potential much sooner than others, which have been maintained on a medium without PGR. However, in our experiments, the EC of Japanese cypresses maintained in the absence of PGR showed a tendency to embryo development and a decline in proliferation over time. This result was consistent with the results reported for other Japanese conifers (Maruyama et al, 2000 Maruyama et ah, 2005 Maruyama et ah, 2007).
