Morphological Studies on the Regularity of Shoots Development in Rice Plants:IV. Structural regularity in the growth types of tillers and their mother shoots
Growth Growth type Leaf Morphogenesis Oryza sativa Rice plant Shoot development Tiller
2009/7/30
It has already shown that the main shoots of two different growth types coexist even in a precisely cultured plot. These types are : (i) N type with n leaves, (ii) N-1 type with n-1 leaves ; these typ...
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 (...
Morphological Studies on the Regularity of Shoot Development in Rice Plants : VI. The regular relationship between leaf primordia developments in the main shoot and primary tiller buds
Anatomy Differentiation Leaf primordium Oryza sativa L Plastochron Rice plant Shoot apex
2009/7/28
Rice cv. Koshihikari was seeded and grown for three years. Seedlings were dissected under a stereoscopic microscope for anatomical studies at the following stages; in n.1 age when the (n+1)-th lamina...
Morphological Studies on the Regularity of Shoot Development in Rice Plant : V. The regular modification in changes of organ length on main shoot with the same total leaf number
Growth Growth type Internode Leaf Oryza sativa L Rice plant Shoot development
2009/7/27
In a field plot where rice seedlings were planted as a single per hill, a difference of one leaf appeared in the total leaf number of the main shoot. Therefore, the main shoot with 'n' leaves and thos...
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...
Morphological Studies on the Regularity of Shoot Development in Rice Plants:VII. The mechanism to control the start of internodal elongation and the regular distribution of elongated internodes on stems
Anatomy Elongation Internode Mechanism Morphogenesis Oryza sativa L
2009/7/22
The distribution of elongated internodes on stems in each plant was compared among the main shoots and tillers, and GA3 was applied to the plant to determine the primordial internodes which are sensit...
Method of Estimating the Variation of Growth Stages on the Basis of the Regularity of Morphogenesis in Rice Plants
Critical stages of cool temperature Development model Developmental stage Flowering date Glumous flowers Growth variation Mature stage
2009/7/8
We modified the development model established for early warning of cool-weather damage to estimate the percentage of productive panicles and glumous flowers at a specific stage such as meiosis, in th...
The Influence of Phosphate Treatment on Chromosome Segregations and Tetrad Regularity and Using Tetrads in Determination of Regular Meiosis Diploid and Autotetraploid Meadow Fescue（Festuca pratensis Huds）
Phosphate Treatment Chromosome Segregations Tetrad Regularity Regular Meiosis Diploid
2009/1/23
This study was carried out under greenhouse conditions in 1994-1995. The influence of phosphate treatments (0, 1, 2, 3 and 4g P 2 O 5 /pot) on chromosome segregaiton at the first anaphase (AI) and tet...
