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...
Analysis on Root System Morphology in Rice with Reference to Varietal Differences at Ripening Stage
Nodal roots 0ryza sativa L Root depth index Root distribution Root length Root weight
2009/7/28
The morphology of the rice root system was established by analyzing varietal differences. Four rice varieties, Koshihikari, Dobashi 1, IR36 and Lemont, were grown in an experimental paddy under ordina...
Varietal Differences in Germination Rate, Storability, and Flooding Tolerance of Soybean Seeds Produced from Different Cultural Seasons and Locations
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...
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
2009/7/15
Varietal differences in the number and cross area of large vascular bundles (LVs) at the neck internode were investigated in 18 rice cultivars. There were two kinds of LVs in Chinese japonica (CJ), Ja...
