Ecological studies on the timberline of Mt. Fuji
Journal of Plant Research - Tập 100 - Trang 349-363 - 1987
An ecological study of dry matter production was made in a dwarf forest dominated byAlnus maximowiczii at the timberline of Mt. Fuji. Annual gross production was estimated by two methods, namely the summation method using stem analysis and total photosynthesis calculated from leaf area and photosynthetic rate per leaf area. Seasonal changes in relative light intensity and in leaf area were measure...... hiện toàn bộ
Embryology of Cardiopteris (Cardiopteridaceae, Aquifoliales), with emphasis on unusual ovule and seed development
Journal of Plant Research - Tập 129 - Trang 883-897 - 2016
Cardiopteris (Cardiopteridaceae), a twining herb of two or three species distributed from Southeast Asia to Northern Australia, requires an embryological study for better understanding of its reproductive features. The present study of C. quinqueloba showed that the ovule and seed development involves a number of unusual structures, most of which are unknown elsewhere in angiosper...... hiện toàn bộ
Increase in activity of IAA-synthesizing enzymes prior to cell division
Journal of Plant Research - Tập 91 - Trang 93-95 - 1978
During the course of cell division in synchronously dividing cultured tobacco cells, the activity of IAA-synthesizing enzymes increased first, then the amount of endogenous IAA, and finally, the number of dividing cells. Based on the results obtained, we discussed the role of endogenous IAA in cell division.
Biosystematic studies inErythronium (liliaceae-tulipeae)
Journal of Plant Research - Tập 88 - Trang 163-176 - 1975
The floral biology ofErythronium japonicum has been studied from two approaches: a reinvestigation of its floral morphology and a pollinator case history. The perianth, differentiated into a sepal and petal cycle, has a tubular, but free arrangement basally around a slightly stipitate ovary. The two cycles of stamens with dimorphic filaments are positioned by the differently lobed auricles of the ...... hiện toàn bộ
Cellular localization and detergent dependent oligomerization of rice allene oxide synthase-1
Journal of Plant Research - Tập 128 - Trang 201-209 - 2014
Allene oxide synthase-1 from Oryza sativa (OsAOS1) localizes to the chloroplast, but lacks a putative chloroplast targeting sequence typically found in dicot AOS. Here, kinetic parameters and the oligomerization state/subunit composition of OsAOS1 were characterized in vitro in the absence or presence of detergent micelles. The catalytic efficiency (k

Mating types and reproductive isolation inClosterium ehrenbergii meneghini
Journal of Plant Research - Tập 94 - Trang 325-334 - 1981
Numerous clones ofClosterium ehrenbergii Meneghini were isolated from soil or liquid samples from various localities and clonal uni-algal or axenic cultures were established. Mating types of these clones were determined by crossing with tester clones. No homothallic clone has been encountered, even in such an extensively surveyed area as that in Japan. By some unknown factors, mating type ratios h...... hiện toàn bộ
Competition between two naturalized dandelions,Taraxacum officinale weber andTaraxacum laevigatum DC., in mixed cultures with different levels of soil moisture
Journal of Plant Research - Tập 99 - Trang 1-14 - 1986
Taraxacum officinala andTaraxacum laevigatum were grown in mixed stands at various plant densities and mixing ratios with various levels of soil moisture to formulate the effect of soil moisture on the competitive relationship between the species. In pure stands, the mean plant weight—plant density relation for each level of soil moisture could be described by the reciprocal equat...... hiện toàn bộ
Growth strategies differentiate the spatial patterns of 11 dipterocarp species coexisting in a Malaysian tropical rain forest
Journal of Plant Research - Tập 122 - Trang 81-93 - 2008
We examined relationships between mortality rate, relative growth rate (RGR), and spatial patterns of three growth stages (small, medium, and large trees) for 11 dipterocarp species in the Pasoh 50-ha plot. Mortality rates for these species tended to be positively correlated with RGRs, although the correlation was significant only at the small-tree stage. Seven species with high growth and mortali...... hiện toàn bộ
Callose and cellulose synthase gene expression analysis from the tight cluster to the full bloom stage and during early fruit development in Malus × domestica

Consistent scaling of whole-shoot respiration between Moso bamboo (Phyllostachys pubescens) and trees
Journal of Plant Research - Tập 134 - Trang 989-997 - 2021
Both Moso bamboo (Phyllostachys pubescens) and tree forests have a large biomass; they are considered to play an important role in ecosystem carbon budgets. The scaling relationship between individual whole-shoot (i.e., aboveground parts) respiration and whole-shoot mass provides a clue for comparing the carbon budgets of Moso bamboo and tree forests. However, nobody has empirically demonstrated w...... hiện toàn bộ
