Varietal Difference on Morphological Change of Leaf Blade by Different Nutrient Concentration of Culture Solution in Rice Seedlings
Concentration of culture solution Leaf blade Leaf position Morphogenesis Rice Seedling stage
<
2009/8/4
To make clear the internal leaf morphology concerned with varietal difference in specific leaf area (SLA) response to concentration of culture solution at the seedling stage, varietal differences in ...
Varietal Difference and Temperature Response of Local Soil-Reduction around Germinating Rice Seed
Direct sowing Germination Rice Seedling emergence Soil reduction Varietal difference
<
2009/7/31
Local soil-reduction occurs around rice seed when it is sown into flooded soil, and the reduction inhibits seedling emergence. Seedling emergence is more inhibited when the reduced soil area is forme...
Varietal Differences of Root Systems in Winter Wheat Seedlings
Root length Root system Spread of root system Triticum aestivum L Varietal differences Winter wheat
<
2009/7/30
Varietal differences in root system morphology in winter wheat (Triticum aestivum L.) were investigated using seed pack growth pouches in a greenhouse. Different genotypic cultivars, shorter B-288 D f...
Varietal Differences and Geographical Distributions in the Growth of Mesocotyl and Internodes of Rice (0ryza sativa L.) Seedlings
Core collection First internode Internode elongation Mesocotyl Rice
<
2009/7/28
The characteristics of internode elongation were investigated using 262 rice cultivars including 260 from IRRI's core collection and two recommended Japanese cultivars, Sasanishiki and Koshihikari. St...

Cultural season Germination Locality Seed flooding tolerance Soybean Storability Varietal difference
<
2009/7/27
Seed germination rate, storability, and flooding tolerance are important factors involved in soybean production in high-temperature and excessive-moisture areas. To evaluate the effects of environment...
Seedling Establishment of Rice Sown on Soil Surface in Flooded Paddy Field : I. Varietal difference in seedling establishment
Direct seeding Establishment Floating seedling Flooded paddy field Rice Seedling establishment
<
2009/7/23
Field experiments were carried out to clarify the differences and key factors in the rate of seedling establishment among rice varieties sown on the soil surface in flooded paddy fields. The percentag...
Varietal Differences of Rice in Differentiation and Degeneration of Secondary Rachis-branches and Spikelets in Terms of Their Nodal Distribution on a Rachis
Degenerated spikelet Differentiated spikelet Ear type Primary tiller Rice Secondary rachis-branch Spikelet number
<
2009/7/23
The higher number of spikelets in modern rice varieties with higher yielding ability (MVs) results from the higher number of secondary rachis branches (SBs). It is conjectured that rice cultivar Takan...
Varietal Differences in the Number and Cross Area of Large Vascular Bundles at the Neck Internode of Rice
Area of vascular bundle Neck internode Oryza sativa L Primary rachis branch Rice Ripening
