deer-proof fence dwarf-bamboo Mt.Ohdaigahara sika deer small rodent
2009/8/28
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...
Dynamics of Undergrowth and Its Application to Vegetation Control of Planted Chamaecyparis obtusa Endl.Forests with Special Reference to Mitigation of Surface Soil Loss
Chamaecyparis obtusa plantation dynamics of undergrowth soil erosion control stand density control vegetation control
2009/8/28
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...
Varietal Difference in Nitrogen Response of Rice Plants with Special Reference to Growth Duration
Growth duration Nitrogen response Rice variety
2009/8/6
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 ...
Heterosis in Japonica/Indica F1 Rice Hybrids with Special Reference to Nodal Root Function
Dry matter partitioning Heterosis Japonica/indica F1 hybrid Nitrogen uptake
2009/8/6
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...
Relation between the Leaf Color of Rice and the Stomatal Aperture Shown by the Infiltration Method with Special Reference to the Climatic Conditions
Infiltration method Leaf color Rice Saturation deficit Solar radiation Stomatal aperture
2009/8/6
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...
Comparative Root Anatomy of Seminal and Nodal Root Axes of Summer Cereals with Special Reference to the Development of Hypodermis and Cortical Sclerenchyma
Cereal Cortical disintegration Cortical sclerenchynla Heterorhizy Hypodermis Nodal root
2009/8/5
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...
Influence of Planting Density to Podding of Soybean Plants with Special Reference to Raceme Order
Flowering Planting density Podding Podding efficiency
2009/8/5
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...
