The photosynthetic rate in the flag leaf of rice at the full heading stage was examined in three japonica varieties, Koshihikari, Aikoku and Asanohikari, and the indica high-yielding variety Takanari ...
We examined the relationship between dwarf-bamboo growth and small rodents on Mt. Ohdaigahara where the population density of sika deer (Cervus nippon) has been increasing and trunk debarking by the d...
Viewed from the erosion control in Hinoki cypress plantations, the dynamics of undergrowth was studied in order to apply the stand density control to vegetation control. Seventeen study plots were set...
Potential sink size was correlated with plant nitrogen (N) at late stage of spikelet initiation and flowering, and with growth duration (GD) in DS and WS. The amount of N in plant at critical growth ...
Although root system of japonica/indica F1 hybrids of rice (Oryza sativa L.) must play an important role for expression of heterosis, few studies have been conducted. This study was carried out to eva...
Rice plants (cv. Yamabiko) were cultivated in paddy field with different manure levels and were tested for variation in stomatal aperture by the infiltration method using a mixed solution of ethylene...
Seminal and nodal root axes play an important role as conducting pathways for transporting substances into and out of roots. The anatomical feature of the tissue at the basal portion of these axes in...
To clarify the influence of planting density on podding of soybeans, field experiment was conducted in terms of the identification of the raceme order (RO). Soybean cultivars 'Tatisuzunari' and 'Tamah...
This study was conducted to investigate the characteristics in terms of the identification of the raceme order (RO) for flower and pod shedding in soybean plants (c.v. Tatisuzunari). The control plot ...
Effects of soil water stress on root development of winter wheat seedling was studied with special reference to elongation and branching of seminal roots. Japanese wheat variety Norin 61 was planted ...
Winter-depression of photosynthesis in overwintering leaves of tea (Camellia sinensis (L.) O. Kuntze) plants was investigated with special reference to cultivar and leaf age. Photosynthetic activity o...
The deveropmental direction of the crop production in the mountain area with special reference to small:scale farming in Chugoku district.
The 15N natural abundance method has been widely used for evaluation of symbiotic N2-fixation. The method inevitably requires a reference plant that reflects soil derived δ15N similar to that in a N2-...
The effect of time and rate of nitrogen application on root growth and their relations with constituents of top per hill were investigated using Chinese F1 hybrid rice (cv. Shanyou 63) under water cul...
Before anthesis, rice antipodal cells are located between nucellar cells and a central cell, and have a large-sized lobed nucleus and many cell-wall ingrowths abutting the nucellar cells. An outstandi...
