2009/9/10
Distribution of the moisture content across stem wood at breast height in Acacia mangium, A. auriculiformis,and hybrid Acacia trees grown in 3 Asian countries was evaluated. Moisture contents of the s...
Natural Drying of Logging Residue Stems along a Forest Road and on a Paved Landing
drying location logging residue moisture content natural drying woody biomass
2009/8/28
An experiment on the natural drying of Chamaecyparis obtusa logging residue stems was carried out to determine the potential for use of this material as woody biomass (e.g. wood chip bio-fuel). The ex...
Sterile Spikelets of Rice Plants Induced by Low Temperature in 1988:Difference in heading date among stems and spikelet locations on the panicle
Heading date Main stem Rice plants Spikelet locations on the panicle Sterility Susceptibility to low temperature
2009/8/6
A large number of sterile spikelets were induced by low-temperature at the booting stage of rice plants during the middle to the end of July in 1988. The authors investigated various aspects of occur...
Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-leaf Blades by Leaf Position on the Stems of Rice Plants:I. Variation of chlorophyll meter values and mechanism of leaf formation
Chlorophyll meter Concordance Cultivar Half-leaf blade Leaf blade width Leaf color
2009/7/29
We clarified that the degrees of the difference in color between outside and inside half-leaves were unexpectedly large, which ranged from 1.3 to 5.4 values by the Minolta chlorophyll meter SPAD-502 (...
Analysis of the Number of Spikelets per Panicle on the Main Stems, Primary and Secondary Tillers of Different Rice Genotypes Grown under the Conventional and Nitrogen-Free Basal Dressing Accompanied with Sparse Planting Density Practices
Cultivation practices Main stems Number of Spikelets Primary tillers Rice cultivars Secondary tillers
2009/7/29
The number and development of spikelets on a panicle directly affect the grain yield. In this study, we examined the differences among various rice cultivars in the number of spikelets per panicle (NS...
Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-Leaf Blades by Leaf Position on the Stems of Rice Plants:II. Uneven translocation of nitrogen between outside and inside half-leaves
Chlorophyll meter value Distribution Half-leaf blade Leaf blade width Nodal root Translocation
2009/7/27
We have reported in a previous paper that the outside half-leaf had a smaller volume and deeper leaf color than the inside half-leaf. The half-leaf color was not dependent only on the difference in le...
