The influence of planting density on root growth and its relationship to leaf and tuber growth were investigated with two maincrop varieties in the potato. Three levels of planting density were exami...
The effect of photoperiod on the distributing pattern of flower buds along a stem and the growth of leaves in Trapa bispinosa Roxb. was examined by the photoperiodic treatments of seven artificially c...
To clarify the effect of seed-rhizome weight at planting on the vegetative growth and yield of new-rhizomes in edible canna, seed-rhizomes weighing 20-500g (fresh weight) were planted at 1.0m×0.5m spa...
The purpose of this study was to clarify the effects of triacontanol (TRIA) on the roots growth and the appearance stage of the effects, and to clarify the relationship between root development and hu...
Most of the supernodulating soybean lines were agronomically inferior to conventional genotypes. Our previous tests with ‘En6500’, a supernodulating mutant derived from a variety ‘Enrei’, revealed tha...
For improving the yield of drilled sugar beet (Beta vulgaris L. ssp. vulgaris), it is important to promote germination and early growth. In this study, the priming of sugar beet seeds was examined in ...

The objective of this study was to obtain physiological information for the increasing yield of soybeans at drained paddy fields by controlling the water table level. We studied the effects of variou...
Yield and its component organs of rice (cv. Akihikari) were examined for populations grown under two different CO2 concentrations (350 and 690μLL-1)×four temperature regimes in temperature gradient ch...
Phenological development, biomass production and the related growth characteristics of rice (cv Akihikari) in canopy were measured over the entire growth period under different CO2 concentrations and...
The effects of foliar application of triacontanol (TRIA; 10ppb) on the ripening of rice were investigated under the condition of shading after heading and of low temperature before heading. The shadin...
Response of potato genotypes (Solanum tuberosum L.) to increase in planting density was examined. Three potato cultivars (Irish Cobbler, May Queen and Dejima) and two planting densities (5 and 10 pla...
Effects of combined treatments of CO2 (400, 660, 1200 ppm) and air temperature (outdoor tracking, outdoor +2°C) on growth and yield of rice (Oryza sativa L. cv. Nipponbare) grown in growth chambers un...
The effects of planting pattern and planting distance on the growth and yield of turmeric (Curcuma longa L.) were examined in Okinawa Prefecture situated in southern Japan. The dry weights of shoot an...
Turmeric (Curcuma longa L ) plant species produces different sizes of daughter rhizomes (R) and mother rhizomes (MR), which are the only propagules (seed) for its cultivation. Here, we evaluated the e...
